Welcome As Chris Packham points out in his column this issue, whether it’s badgers, sharks, “killer” hornets, “huge” spiders or “dangerous” ragwort, the British media rarely let environmental understanding get in the way of a story. And that journalistic nose for news really starts twitching when city foxes stray into people’s homes, which puts our leopard cover story into real perspective (p36). In Mumbai, one of the world’s most populous cities, there have been increasing reports of conflict between people and the leopards who live there, though they are seldom seen. Just imagine the flurry of outraged alliterative headlines they would provoke in our own tabloids! But it turns out that the tension has partly been caused by leopard-translocation policies, which can now be reformed. As our writer Janaki Lenin explains, the good news from India’s cities is that by adapting we can co-exist with these incredible cats. In the UK, we could learn a great deal from that kind of attitude to wildlife. Matt Swaine Editor matt.swaine@immediate.co.uk December 2014

WILD DECEMBER WHAT TO SEE O NATURALIST SKILLS O DISCOVERIES 4 RED SQUIRREL
Survival skills Like their burlier grey relatives from North America, our native red squirrels don’t hibernate. “Reds are amazingly tough,” says Mel Tonkin of the Scottish Wildlife Trust. “They grow thick winter coats and will be out and about in all but the harshest weather, searching for the lifesaving caches of tree seeds and fungi that they hoarded in autumn. You can still spot their tracks even when there’s heavy snow cover.” This Cairngorms individual eyeballed photographer Jules Cox during a December blizzard so fierce that his camera kept refocusing on the driving snow. Your best chance of spotting a red squirrel in the Highlands this month is to check one of the feeding stations stocked all winter – try the visitor centres at RSPB Abernethy (there’s also a webcam) or the Scottish Wildlife Trust’s Loch of the Lowes reserve.

4 MOON JELLYFISH
Bloom boom Blooms of moon jellyfish, pictured here in a sea loch on Scotland’s Isle of Mull, are a reliable indicator of distressed oceans, says marine biologist Lisa Gershwin. “These jellyfish love disturbed ecosystems. They like warm water, as it makes them grow faster, breed more and live longer; they like having no predators and competitors; and they really like coastal construction, as it gives their polyp stages somewhere to settle and grow.” Figures for jellyfish populations around the globe tell a worrying story. “In Korea, researchers tracked small jellyfish for 20 years, recording a five-fold increase. In Japan, the massive Nomura’s jellyfish used to bloom every few decades, but now does so almost every year, with 500 million per day drifting into the Sea of Japan from China. And the infamous Mnemiopsis leidyi now makes up 95 per cent of all of the biomass in the Black Sea, having been inadvertently introduced in the late 1980s.” O Help out by reporting any jellyfish blooms you see to the Marine Conservation Society at http://bit.ly/1iYBeqn Photograph by Alex Hyde

4 PAINTED GHOST CRAB
Crab meet Painted ghost crabs feast on a dead sealion at Cerro Brujo Beach, on San Cristóbal island in the Galápagos archipelago. Enrique del Campo had just 30 minutes to approach and photograph the behaviour without scaring the crustaceans away. Most ghost crabs are solitary and aggressive, but painteds are highly social, assembling in pods that move in co-ordinated ranks across sandy beaches. “They will commonly scavenge when the opportunity arises, tracking down a carcass using chemoreceptors on the tips of their legs that ‘taste’ the sand,” says Thomas Trott, associate professor of biology at Suffolk University, Boston, USA. “However, their primary method of eating is ‘deposit feeding’, in which they use specially adapted mouthparts to sift micro-organisms from grains of sand scooped up on the beach.” Photograph by Enrique del Campo

5 EIDER
m TWEET OF THE DAY
T A few-score metres offshore, a flock of eider bobs in the swell. Like all British ducks the sexes look very different. The female is brown with dark stripes, while the male is white and black with a powdery green hindneck and rosy flush to his breast. This strictly coastal species favours rocky shores, where it dives for crustaceans such as molluscs. The bird is known as ‘Cuddy’s duck’ in Northumberland after St Cuthbert, a local saint. BEST SPOT Bamburgh

4 RAVEN
S The winter roosts of rooks and jackdaws have become established destinations for wildlife watchers, but those of the raven are less readily visited. Britain’s largest congregation assembles in a forest on the Welsh coast. Though numbers have dwindled to less than half their former peak of 2,000 birds, the sight and sound of hundreds of these hulking black forms gathering in the gloom remain impressive. Ravens may use their nightly roost to exchange news of animal carcasses to scavenge. BEST SPOT Newborough Forest Anglesey
7 MOUNTAIN HARE
X By December mountain hares have undergone a transformation that is unique across our three lagomorph species – moulting from brown summer fur to winter white. The intention is clear: to continue a camouflaged existence on moors and fells that, by rights, should be snowbound this month. However, our ever-milder climate means that much of the mountain hare’s patchy distribution may still lack a white blanket. Either way, December is a great month to spot hares on a rugged ramble across favoured hills. BEST SPOT Crowden Derbyshire
6 CHINESE WATER DEER
S For much of the day the rarest deer in Britain skulks and slumbers in dense waterlogged vegetation such as Norfolk’s coastal marshes and Cambridgeshire’s Fens. But as daylight evaporates this teddy-bear-faced cervid stumbles onto neighbouring fields for a night of browsing. If alarmed the deer typically freezes, utters a throaty cough then lopes towards safety. First introduced to Britain during World War II, our population has reached 4,000 individuals, one-fifth of the world’s meagre total. BEST SPOT Woodwalton Fen Cambridgeshire

UNDERSTAND MALE AND FEMALE PLANTS
C
hristmas is a time for gifts, wine and song… and also for discovering the rather special reproductive strategy of dioecious plants. While most flora have both male and female organs on the same plant, these species have either male or female individuals. “We have just 20 or so species like this in Britain, plus the willows and docks,” says botanist Trevor Dines of Plantlife. “Coincidentally, they include the three we associate with Christmas – holly, ivy and mistletoe.” Other dioecious species are red and white campion, dog’s mercury, stinging nettle, yew and juniper. Ash trees are often polygamodioecious – that is, there are a few male flowers on otherwise female trees, and vice versa; sometimes their branches are either all-male or all-female. Dioecy is important to the conservation of juniper. “Many relict juniper populations in northern England and on islands are single plants, so as lone males or females they are doomed,” says Trevor. “Plantlife is introducing specimens from the other sex to help them start setting seed again.”
Dispersal All five thrush species found in Britain in winter love holly berries, dispersing the stone fruit through their droppings. Mistle thrushes are often highly protective of their tree, noisily guarding its berries against other birds.
FEMALE HOLLY Ilex aquifolium
Male flower Has four prominent, pollenbearing stamens that splay out in an ‘X’ shape. Seen in spring and summer, from May.
Berries Only female holly produces berries, known as drupes. Botanically speaking, the fruit is the hard ‘stone’ at the centre, the exocarp is the red outer skin and the mesocarp is the fleshy orange layer in between.
Female flower A fat green ‘boss’ in the middle is the ovary, which forms the base of the yellowish stigma. There are also four stamens, but these don’t produce pollen. Flowering season as male flowers.
Leaves Evergreen. New low growth has more spines as it is within the browsing zone of deer; above 2–3m, leaves are smoother-edged. Fallen leaves decay slowly – look for their paper-thin skeletons on the ground.
Foodplant Holly is a key food for about 30 species of invertebrate, including the caterpillars of lovely insects such as the holly blue butterfly and privet hawkmoth.

A CLOSER LOOK AT DIOECIOUS PLANTS Dog’s mercury Forms carpets in shady ancient woodland; flowers February–April. Flowers on male plants resemble yellow catkins, and on female plants develop into paired fleshy fruits. But spreads mostly by rhizomes, creating single-sex patches on woodland floors.

Red campion
Abundant plant of woodland, hedgerows and verges, with a long April–August flowering period. Female flower has five tall white styles (the structures that bear the stigmas) at the centre; the male flower has a cluster of 10 yellowish stamens.

Bat hibernation PHILIP BRIGGS
When do bats enter hibernation? It’s triggered by shorter days and hormonal changes, typically starting from mid-October. But in mild weather bats may remain active into November or December, particularly in the warmer south and west and cities.
How do bats choose winter roosts? They need undisturbed places with a cool, constant temperature and high humidity, such as caves, mines, tunnels and cellars. Six UK bats may hibernate in trees: the brown long-eared, noctule, Nathusius’ pipistrelle, barbastelle, Leisler’s and Bechstein’s.
Which species hibernate in houses?
O Centipedes such as the abundant species Lithobius forficatus stay active all winter in leaf litter and compost heaps.
O Bullfinch numbers are down 39 per cent since 1967, but garden visits are up. Offer sunflower hearts to attract them.
Pipistrelles often roost in houses in summer, but in winter are much less conspicuous, though you may find them in outbuildings or tucked away in gaps. Callers to the Bat Conservation Trust helpline have seen bats in log piles and even behind a picture on a wall!
What changes do they go through? Bats enter an extended torpor to conserve energy stores, by reducing their metabolic rate. Their heartbeat slows, they may breathe just once an hour and their body cools, usually to within 1–2°C of ambient air temperature. Clockwise spiral from top: Chris Gomersall; Rupert Soskin; Steffen Hauser/Alamy; David Whitaker; Alex Hyde; Steve Round
Do bats wake up mid-hibernation? Bats wake frequently to drink and may also mate in winter. On warm days they emerge to feed – especially long-eared bats, which pick crawling invertebrates off surfaces and so are less reliant on air temperatures being high enough to sustain flying insects. O Goldcrests can be amazingly tame – look for them flitting around garden conifers. They may even visit fat balls.
December 2014
O Mahonia flowers are a lifeline for any drowsy queen bumblebees that awake on unseasonally mild midwinter days.

ROBERT FULLER NORTH YORKSHIRE “I was surprised to discover that a pair of kestrels, two jackdaws and a tawny owl had been inspecting a nestbox in my garden. I put the nestbox up to attract the kestrel pair, and in spring rigged a camera so I could watch them. After the falcon chicks fledged, it was occupied by stock doves that abandoned two eggs. A video I took shows a kestrel taking an interest in the eggs. I’m hoping the kestrels will use the nestbox again, as a chick would make a good model for next year’s paintings!”

ichens are symbiotic entities, each made up of a fungus and a photosynthetic alga. The fungal structure, or thallus, provides shelter and protection for the algae, which pay rent by leaking nutrients. Lichens generally favour clean air and humidity, so are found in greater abundance and diversity in western Britain. But wherever you live, there will be lichens nearby. There are three main forms: leaf-like foliose lichens; encrusting or crustose types; and tufted or fruiticose forms. Look for swollen spore-producing bodies called apothecia, which can be highly distinctive and intricate. Lichens are informative, too. Ecologists use pollutionsensitive lichens as indicators of air quality, ‘natural navigators’ refer to growth patterns to gauge direction, and historians can use the spread of lichens to estimate the age of buildings, gravestones and ancient monuments.

Hunting raptors O Starling roosts are often targeted by peregrines (left) and sparrowhawks, triggering dramatic evasive action as the flocks split and reform. Visit http://bit.ly/1wvt9CL to see a simulation from the University of Warwick.
Assembly flocks
Main: Laurie Campbell; clockwise from left: Laurie Campbell: Sam Hobson; Colin Varndell; Drew Buckley; David Tipling; John Waters/NPL (captive)
O In late afternoon starlings fly to the roost site from their feeding areas up to 50km away. As dusk approaches they gather nearby on wires, trees and aerials, from where ever-larger flocks head off to join the main murmuration.
Peak murmurations occur during cold snaps from December to February. Aerial displays last longer in clear, calm conditions.
DISCOVER starling roosts New research shows how huge winter starling flocks co-ordinate their massed aerobatics. hape-shifting congregations of thousands of starlings at dusk, called murmurations, have an almost volcanic energy. “Carousels of birds chimed and merged, like iron filings made to bend to a magnet,” writes Tim Dee in The Running Sky. But explaining how starlings gather in such numbers and mostly avoid mid-air collisions (fatalities are

known in some flocking species) has long provoked much debate. Now a multi-disciplinary study by the University of Warwick has found that flock density is key. “A bird is safer from predation if it joins a big, dense flock,” says researcher Dan Pearce. “So in theory large flocks would eventually be totally opaque. But we discovered that birds select
the optimum density so they never quite get that packed. If you look at photos of flocks, there will always be gaps where you can see the sky. “Each starling constantly monitors the trajectories of about six or seven of its nearest neighbours, while also making adjustments so that it can still see light areas – that is, patches of sky. It must always be able to gather vital information about its surroundings.” Amazingly, this process is entirely instinctive. “The birds do it almost without thinking,” says Dan. December 2014
WILD DECEMBER BEST LOCATIONS Starling roosts vary in size and shift location from year to year – here are some of the most reliable.
European arrivals O Many British starlings remain here all year but move to milder coastal, western and southern areas in winter. Their numbers are swelled by migrants from the Baltic, Scandinavia and Russia that may double the population to about 16 million birds.
NEAR GRETNA, DUMFRIES & GALLOWAY Roost site is mobile; recently it has been to the west of Gretna, over the village of Rigg.
ALBERT BRIDGE, RIVER LAGAN, BELFAST Big city-centre starling roosts like this are sadly uncommon today.
RSPB SALTHOLME, NEAR MIDDLESBROUGH Flocks gather against a dramatic backdrop of heavy industry.
Safe roost sites O For protection from terrestrial predators such as foxes, starlings often roost in Phragmites reeds growing in water. Dense conifers and ledges on bridges, seaside piers and buildings are also used.
RSPB LEIGHTON MOSS, LANCASHIRE A medium-sized reedbed roost, featured on Autumnwatch.
ROYAL PIER, ABERYSTWYTH Watch from on the pier itself or along the seafront parade.
RSPB FEN DRAYTON LAKES, CAMBRIDGESHIRE Perhaps the most accessible of several roosts in the Fens.
RSPB NEWPORT WETLANDS Large reedbed roost that attracts local pylon-nesting peregrines.
SHAPWICK HEATH/RSPB HAM WALL, SOMERSET Probably Britain’s largest roost. Very popular, so avoid weekends. For more great locations, visit www.discoverwildlife.com
Warmth and chatter O Roosting starlings perch close to one another for communal warmth. Before sleeping, they often preen en masse, and there is a theory that they also exchange information about good feeding sites, though this is difficult to prove. Roosts are certainly very noisy, with thousands of birds calling in a tumult of sound.
December 2014
UK STARLING ROOST SURVEY The Society of Biology and the University of Gloucestershire are organising a national starling murmuration survey this winter. To join in, you need to estimate the size and duration of flocks, and record the time, weather, air
temperature and if any birds of prey were in the vicinity. O www.societyofbiology.org

Seasonably sustainable Enjoy the warm glow of a sustainable Christmas. Environmentalist Julie Hill explains how to reduce your footprint and help wildlife in the process. 1
GET CREATIVE
Use greenery to brighten your home, such as holly and ivy from your back yard – and when you take the decorations down in the New Year, they can be added to an eco-pile in your garden. A birdfeeding wreath is easy to create, and has the added value of supporting your garden visitors in the coldest season. Make the circular base from twisted twigs, wind holly and ivy round the wreath, and stuff fat and seeds into the scales of pine cones.

WRAP IT UP
Encourage your children or grandchildren to potato-print brown paper to wrap your presents in, and, once gifts have been exchanged, try to keep the paper to use again. Or give presents in reusable, personalised fabric bags. You can make your own tree decorations or garlands out of recycled cards or wrapping paper kept from previous years.
2
WILDLIFE PRESENTS 3
Many wildlife charities offer the chance to adopt a species on behalf of someone else, or to purchase annual membership as a gift. Alternative ideas include buying seeds for your relative or friend to start their very own mini-meadow, or a wildlife home for them to put in their garden, such as a birdbox, insect hotel or hedgehog house.
4
THINK LIGHTING
According to the Carbon Trust, LED Christmas lights on average consume between one-fifth and oneeighth of the electricity of non-LED equivalents. When you leave the house remember to turn the lights off – make sure that the switch is easily accessible. Or you could put them on a timer.
LOCAL FOOD
When sourcing your Christmas meal, do your best to support local businesses and buy organic. Try to buy ethically produced meat that hasn’t been reared on a factory farm, and vegetables that haven’t travelled thousands of kilometres in order to reduce your carbon footprint. Any raw food waste (such as potato peelings) can be added to the compost pile in your garden – visit www. lovefoodhatewaste.com for more advice on cutting down the amount you throw out.

TREE RECYCLING
According to recycling body WRAP (the Waste & Resources Action Programme), in 2007 about 250 tonnes of Christmas trees that could have been recycled for composting and wood chippings were thrown out after Christmas. Fortunately many councils now set up tree-recycling points. Another option is to add the tree to an eco-pile in your garden and allow it to rot down – such areas make brilliant habitats for insects, which in turn attract birds to your back yard. Visit www.recyclenow.com/ what-to-do-with/christmas-trees to find out more.

SOURCE YOUR TREE
There are arguments for artificial trees that can be used again and again. But if you prefer a real one, consider getting a living tree that can be kept in a pot and brought out each year. Some plantations use herbicides to control weeds, so do check when you buy your tree – and try to source it locally. + FIND OUT MORE The Secret Life of Stuff: A Manual for a New Material World by Julie Hill is available now (RRP £8.99, Vintage Books).

Not seeing the wood for the wind farm What? Tree-roosting bats are attracted to turbines. It is tree-roosting species that are mostly likely to be killed in close encounters with the turbine blades of wind farms, and new research shows why. Tree roosters, such as the hoary bat in the USA (left), are attracted to turbines from downwind, especially at relatively low turbine speeds when the air currents they generate are similar to those around the tall trees that the bats hunt around and roost in.

Orcas that are housed with bottlenose dolphins utter clicks and whistles that are intermediate between both species, according to a new study. It’s not that the whales have learned to speak dolphin as such – it’s more akin to speaking English with a French accent when in France. But their ability to adjust their vocalisations to whoever is around them may facilitate social cohesion between different groups of whales.

Gang welfare What? Male-bonding monkeys may have set the scene for human civilisation. Not all male primates are violently competitive (see the chimp story on p25). New research shows that male Guinea baboons park their differences and form co-operative bonds, even with unrelated individuals. The result is that the species can form large, cohesive social groups. It also raises the intriguing possibility that a similar development in human ancestors paved the way for our own remarkably co-operative societies. SOURCE PNAS LINK http://bit.ly/1wb56rP

Vive la change! What? Metamorphosis could explain the wide diversity of insects. The evolution of distinct larval, pupal and adult stages may be behind the staggering diversity of insects alive today. A new analysis of the insect fossil record reveals that groups such as butterflies and beetles, which undergo complete metamorphosis, have diversified faster and been less prone to extinction than others, such as grasshoppers and cockroaches, that start life as miniature versions of the adults. The advantage of complete metamorphosis may be that it reduces competition between adults and young. SOURCE Proc. Roy. Soc. B LINK http://bit.ly/1wlREkR

Predatory personalities What? Sharks can be introverts and extroverts, too. It’s hard to tell from their cold, unblinking stares, but individual sharks have rudimentary personalities.

Natural born killers What? Humans not to blame for chimp violence, say researchers. Male chimps have a ruthlessly violent side – even ‘murders’ of other chimps are not uncommon. But is this behaviour entirely natural, or has it been exacerbated by habitat loss and other human impacts? An analysis of the circumstances surrounding 152 documented killings shows that ‘murder’ rates don’t increase with human disturbance, but do increase with population size and the number of males in a group. It’s better seen as an effective way of monopolising food or mates, argue the scientists. SOURCE Nature LINK http://bit.ly/XiEoRY

Film local wildlife New camera technology gives you amazing insights into natural history. o matter how big your garden, there’s a fair chance you have wildlife coming close enough to film according to Kate MacRae, a self-taught remote-camera expert. “Cameras in nestboxes and at garden feeders are the best way to start filming wildlife,” she explains. “Everyone can attract birds to their garden, even if all they’ve got is a balcony.” “I’ve just started a project at a house with seven acres of land. The owners knew they had plenty of wildlife, but wanted to see more of it. Almost immediately we captured footage of a kingfisher by their pond, and the next thing we want to see are their local otters.” While you know that birds are likely to appear at a feeder, capturing images of mammals may require tracking skills. “I use a lot

We’ve managed to get images of a roe deer, a badger and a fox with a pheasant in its mouth. Trailcams and cameratraps are really exciting for the kids, and they love looking for places where animals may be visiting to decide where to set up next.” BBC Wildlife Local Patch Reporter Duncan Richardson uses small computers to record wildlife in his garden: “I’ve got one to record the weather, another controlling a nestbox camera and a third for filming hedgehogs that come into my garden.” Turn over to see how easy it is to get started…

WANDA’S TIPS Using a Bushnell NatureView Cam HD Max I’ve been experimenting with this top-of-the-range trailcam, which is so mobile I take it on holiday. It’s superb for close-up details of birds and insects, but it’s best to position it away from swaying bushes that trigger the sensors. Try a few angles and adjust the sensitivity to get good images. My favourite shots include tawny owls (see p31), swallows and foxes (above). Wanda is the picture editor of BBC Wildlife. BBC Wildlife

POCKETWIZARD PLUS II USED BY ROBERT FULLER PRICE £249
This device allows you to fire your DSLR camera remotely, letting you place your camera very close to the subject while you are some distance away. Telephoto lenses produce a short depth of field, but by deploying the PocketWizard I can use a wideangle or short lens and get all the information of the background too. This gives a totally different point of view, with the wildlife in context with its environment. It works particularly well over long distances, in buildings and through glass, and is especially handy if you don’t have an expensive telephoto lens. I have had fantastic results photographing kestrels, curlews (right), tawny owl chicks, lapwings, pheasants and great spotted woodpeckers. www.pocketwizard.com

USED BY ANNABEL HARRIS PRICE $149.95
I’ve been using the Outback for around six months and it’s remarkably good at surviving everything that the Cornish weather can throw at it. It is light, easy to program, can be left in situ for ages and is great value for money. The batteries last a long time and you have the choice of stills, video or time-lapse. The highlight for me was capturing a fox right outside our conservatory door when we were expecting to find frogs or maybe a hedgehog. The fox was making a beeline for the beer trap in the flowerbed – I’m not sure if it was after the beer or the slugs. The trailcam has also revealed how many toads we have in the garden. It does fog up during damp nights, which interferes with its sensors, but this issue affects most trailcams. www.swann.com
USED BY SARA FROST PRICE $449.95
I’ve been using my Spypoint for two years – it’s simple to operate, with options to record video and take still photographs. With a little practice you can capture great footage using this trailcam, but it can take a bit of experimenting to learn the most suitable settings and what position is best for the lens – I’ve had many clips where the lens has been tilted too high and only caught the top of an otter’s head! The device is well waterproofed and works with both Macs and PCs, and the black LED is good for covert filming at night. The ed Sara has film sensitivity settings can be e of illiant footag br tricky to figure out – you need rs with her local otte ailcam. to make it sensitive enough to a Spypoint tr be triggered by moving wildlife, but not so sensitive that it takes a photograph every time a leaf moves. However, it would be nice to have a closer focusing lens (which some Bushnell NatureViews offer; see p27), because I have lost potentially great clips when otters have come to investigate the trailcam, but are out of focus and overexposed.

LYD MINI�CAMERA & SPY�CAMERA ADAPTED HOME�SECURITY UNITS
IN BRIEF THE BEST OF THE REST
USED BY GENEVIEVE LEAPER PRICE From £15 (depends on the model)
These infra-red day and night cameras with a four-channel receiver aren’t actually sold with nestbox use in mind, but for home security or baby monitoring. I’ve been using them since 2012 to film tree sparrows, stock doves, red squirrels and blue tit nests. The system is good for monitoring a number of boxes at once, and you can display footage from several cameras on the same screen. Higher resolution would always be good; likewise a stronger wireless signal. But these devices are great if you plan to monitor a range of nestboxes or locations in one particular area, or if you want to make your own nestboxes for a variety of species. That obviously requires certain DIY skills and significant time to set up.
It was very exciting when red squirrels started using one of my boxes. Two females visited for grooming sessions and occasional daytime naps, though they preferred the large nestboxes for overnight sleeping. Sadly the pair don’t visit any more, but we hope they’ll come back soon. It is very important to realise that these wireless cameras still need power and therefore cables. Many do offer the option to run on batteries, but they only last a few hours – and you can’t keep changing batteries in a nestbox.
Even security cameras can be adapted to record wildlife.

NESTBOX WITH HD CAMERA USED BY SARAH HOOKWAY PRICE £170
This was easy to set up and a pair of blue tits were popping inside after a few weeks. The camera’s resolution is good and it works at night, too. I have my nestbox at the school where I work, so my class could watch the daily dramas. At first we observed moss and grass build up, then to our dismay the parent birds got rid of it all. But finally they completed the nest and we had our first view of the eggs. They all hatched and we watched the young fledge just outside my classroom. It was a great experience for all of us. www.rspb.org.uk (an ultra-high-resolution model is pictured above)
GOPRO HERO3 SILVER 5
BRINNO TLC200 PRO TIME LAPSE CAMERA USED BY ALEX PRICE £209
This Brinno unit is so easy to use and you can decide whether you want it to shoot once every five minutes or once every 24 hours for really long projects. It is a great way to watch things that happen over a long period of time, such as leaves falling off trees or bluebells growing. We have used it to film sunsets, the moon rising, stars moving across the sky and the tide coming in. I have also filmed a ladybird walking up and down a plant, which was funny. The unit has a nice wide-angle lens, but handles close-up, too. The downsides are that I had to buy a waterproof case separately, and when it’s in the case you can’t shift the lens to different angles. I’d also like a way of securely attaching the camera (like I have for my trailcam) so that it’s at less risk of being stolen. www.brinno.com

RASPBERRY PI USED BY DUNCAN
RICHARDSON PRICE £30 (Model B)
The Rasberry Pi is a small computer designed to get kids into programming and it can do some amazing things. I’ve got one mounted on a wall, attached to an HD camera, taking a picture every 10 minutes to create a time-lapse of a year in the life of my garden. It’s wonderful to watch the branches and leaves on the trees reach up to the sun each day. I’ve been using another Rasberry Pi triggered by motion sensors to take HD video inside my blue tit nestbox. The camera costs £20, and the quality is exceptional. I’m planning to also link this to a sensor that can monitor temperature inside the nest and register when parents return to feed the chicks. I’d like to use this data to look at what factors contribute to chick survival. www.raspberrypi.org
USED BY JACK PERKS PRICE £220
I’ve been using GoPros for a few years and have recently started using them in the garden to monitor wildlife. This model shoots in high definition and its fisheye perspective gives a wide-angle view that means you rarely miss the action. It’s much smaller than a trailcam, and more flexible so you can put it in places where you might struggle with other cameras. My main gripe is the lack of battery life – just a couple of hours or even less in cold weather conditions. www.gopro.com

1 TRAILCAM Trailcams can be set up anywhere and then moved easily from one location to another. Unlike nestbox cameras, they don’t require wiring up and work right out of the box. They are triggered by motion sensors and record to an SD card, so that you can easily see the results. There are a host of budget systems on offer for around £50–100, but spend over £150 and you get higher-quality images.

2 NESTBOX CAMERA By installing a simple nestbox camera you can get an intimate view inside the nest and an immediate idea of how successful each brood has been. You need to connect this type of camera to a TV or computer by feeding cables l Nestbox cameras wil through an airbrick or windowthis kind of you e giv frame air vent. Some even view as a live TV feed. come with small microphones, so that you can hear as well as see what is going on. In winter cameras can be converted to a range of other uses.
3 BIRDFEEDER CAM Even a balcony or smaller garden will attract birds, and investing in a specialist feeder camera gives you a ringside seat to observe behaviour up close. Plenty of ready-made models are available, but you can also adapt nestbox cameras for this purpose – just make sure they are in a weatherproof housing. This can easily be adapted from plastic food containers.

4 POND CAM CCTV technology, converted nestbox cameras and trailcams can all be used to capture wildlife around your garden pond. Frogs, toads, birds and small mammals are all possibilities here, and you could use GoPros or similar systems to get photos underwater.
5 BURROW CAM It’s easy to start experimenting with cameras in places other than nestboxes. “Things really started for me when I began to create my own ‘burrow cam’ using an upturned wicker basket with an adapted nestbox camera attached on the inside,” says Kate MacRae. “It took a few days for mice and voles to find the food I’d left inside. In the daytime there was enough light for colour images, and at night the infra-red continued the live feed to my TV.” 30
BBC Wildlife
6 MARTIN CAM There are a range of specialist nestboxes for birds, from tawny owls to house martins, as well as for mammals such as squirrels and hedgehogs. The technology used in the cameras is the same, but the nature of the nestbox and the location in which you put it obviously changes. Choose boxes appropriate to the wildlife in your area and position them carefully.

There are a number of cameras that enable timelapse photography. You can buy cheap apps for your smartphone that allow you to create simple time-lapse sequences, and you can also program computers like a Raspberry Pi or buy a dedicated unit (see p29). The joy of this form of photography is the ability to reveal processes in nature that are often hidden, such as plants growing.
Being able to track wildlife behaviour against the weather starts to deliver some really powerful data. BBC Wildlife Local Patch Reporter Duncan Richardson has set his Rasberry Pi to record the weather every five minutes, and is hoping to use this to look for a correlation between weather, breeding times and blue tit chick survival rates, while also monitoring how often chicks are fed.

I
was knee-high to a grasshopper when I lost my heart to a ladybird. I was in awe of that beetle as it posed, ruby red and glistening, like a blob of polka-dotted blood on the tip of my little finger. And I fell hopelessly in love. Though, to be honest, that ladybird could just have easily have been a maggot or a flea, because I am a lover of life. All life. So the scaremongering, anthropocentric propaganda that adorns our TV screens, radio and newspapers is frankly appalling. Take the exploitation of animals in I’m A Celebrity… Get Me Out Of Here. We have grown out of bear baiting, so why tolerate this barbarism in our living rooms? Exposing children to such carnage can only be confusing: why is one species of animal valued over another? Who gets to decide the hierarchy, anyway? As a society we need to move faster towards a more biocentric culture: there’s simply no time to be making a mockery of the very wildlife that sustains all life on Earth. I have nothing against Ant or Dec, but they’ve hardly helped their audience of millions to value the species that mesh our world together. I’m A Celebrity is an easy target – but it gets worse. It’s a crying shame how few journalists (and, for that matter, politicians) who talk about wildlife with such confidence understand basic ecology. Much reporting about the environment is a national embarrassment. Our terrormongering hacks characterise us as a spineless society of wildlife ‘wets’ by publicising nonsense about killer creatures in our midst. I am sadly spoilt for choice here, for any number of species have been unjustly demonised. In March this year, tabloids reported that Lydia the “killer
fish” had been spotted 1,000 miles off Cornwall; Lydia, an underwater weapon of mass destruction en route to terrorise our green and pleasant land. Except that her species, the great white shark, kills under 15 humans a year, whereas we slaughter tens of millions of sharks annually. We are 1,000 times more likely to be killed by lightning and 1.3 times more likely to have our life terminated by a falling vending machine than to be taken out by a shark. We also have a 100 per cent chance of not being a victim of shark
attack if we stay on dry land where we belong. A perfect opportunity to celebrate the potential arrival of a 16-millionyear-old superstar off Blighty was thwarted by prejudice and ignorance. Top work. Vespa velutina, the Asian hornet, was also in the dock this summer, for conspiracy to sting vast numbers of Britons to death. Trial by tabloid media found this beauty guilty, yet the “deadly invaders” never actually crossed from northern France. Their stings killed precisely one man in France and a handful in their native homeland. Even common wasps are not exempt from hysteria caused by media hype. I am mightily sick of people asking: “But what are wasps for?” I reply: “What are you for?” If only the media used their powers of communication more responsibly, maybe these people would know that wasps perform vital ecological roles of pollination, predation and parasitism in their gardens. Then there are anti-spider tirades, raptor-hating rants, spectacularly ill-informed pieces about neonicotinoid pesticides, the badger cull, the dangers of ragwort or that doubt climate change, by people to whom objective science is a foreign language… I just find it depressing that journalists so often dent progress, when they could be helping to shift perceptions away from humans as supreme beings, disconnected from the rest of the natural world. As an impassioned zoologist and broadcaster, I find this is a hard pill to keep on swallowing. While the promotion of speciesism continues unchecked in the media, the value-to-action conservation gap widens – and that keeps me up at night.

T
his month I’ve been thinking about the teachings of the various faiths. Both Buddhism and Hinduism condemn any kind of cruelty to any living being – nature is sacred, and humans are not considered superior. Islam states that animals must be treated with kindness and compassion, and is opposed to hunting purely for sport. Such hunting is also banned by Judaism, which upholds the view that an act of cruelty against an animal is as bad as an act of cruelty against a human being. So far it appears that most believers – whatever their religion – would be automatic members of the League Against Cruel Sports. Alas, throughout most of history Christians would have been less easy to recruit. A basic tenet of early Christian belief was that animals had neither reason nor souls. Humans were thought greatly superior, and entitled to treat creatures – wild and domesticated – as a commodity. The Roman Catholic Church even condoned a list of acceptable uses of wildlife, which included food, clothing and domestication as pets or beasts of burden. In more recent times, animals’ use in experiments and scientific research has also been deemed acceptable. Of course, many people would argue against the morality of this, but on grounds of animal welfare rather than conservation. Ironically the most potentially destructive category on the ‘what we can do with wildlife’ list might appear to be the most innocuous. ‘Leisure’, in many countries, does not mean birdwatching – it means bird hunting. For years, many of us have been despairingly aware of the massive slaughter of migratory birds in the Mediterranean region. I witnessed it in Malta
in the spring, and was due to visit again this autumn but was warned off for my own safety. The hunters were becoming increasingly aggressive and violent, and may well have targeted me – literally! Instead I watched reports on YouTube, and in the relative absence of birds – dead or alive – I couldn’t help admiring the Maltese architecture, especially the churches. There are a lot of them. It’s a very Catholic country. I found myself thinking like God (no delusions intended). All religions talk of the wonders of creation, and most include
nature and wildlife – something for a creator to be pretty proud of, I’d say. I know that if I had come up with the concept of birds flying for thousands of kilometres in spring and autumn, and being able to navigate by the stars and the Earth’s magnetic pull – some so accurately that they return to the exact same places year after year, I would be pretty pleased. I would also be well miffed if thousands of my little migratory miracles were blasted out of the sky, and left to die for no reason at all. It might even be a sin. Such were my thoughts when a miracle happened. Up on my screen popped a news item featuring auxiliary bishop Charles Scicluna of Malta, out with a team of birders from BirdLife International. There he was focusing his binoculars on a kettle of circling honey buzzards, and explaining that they were God’s work and not to be shot at, but to be admired and enjoyed. A miracle indeed. A bishop with bins! Whatever next? Well, how about a pope with a ’scope? Pope Francis took his name from the patron saint of birds, and his recent pronouncements have been encouragingly liberal. And I have heard a rumour from a genuinely ecclesiastical source that his next ones will be on the theme of the environment. Added to which, the Pope must be feeling a bit guilty about releasing white doves at the Vatican that plummeted and got mugged by crows. Happily, you can find the Pope on Twitter. Here’s a message you can send him that comes in at under 140 characters: “@Pontifex Dear Pope, please help to stop the massacre by declaring the mindless killing of birds an affront to the Almighty.”

Unnecessary conflict: in March 2009 a leopard mauled three people in Guwahati, Assam, before it was tranquillised.
Barely a month goes by without reports of leopard attacks on people in India. But, says Janaki Lenin, it’s perfectly possible for us to live alongside these big cats – even in such a densely populated country.

This leopard was photographed in Ranthambore National Park, Rajasthan. But big cats don’t have to be confined to parks – with a few precautions, people can live safely alongside them.
In February this male leopard caused chaos in Meerut, northern India, injuring several people. Locals were told to stay indoors, while schools and shops were shut.

L
eopards seem to be popping up everywhere in India, and if the media are to be believed they are up to no good. In February this year one created panic in the city of Meerut in Uttar Pradesh, and in August a middle-aged woman made headlines around the world when she single-handedly killed a leopard that had attacked her. The incident took place in Uttarakhand, not far from the setting of Jim Corbett’s 67-year-old tale The Man-Eating Leopard of Rudraprayag. India hasn’t conducted a leopard census, but one estimate puts its population of these big cats at 10,000– 20,000. With numbers of tigers, their mortal enemies, shrinking drastically in the country to 1,520–1,909 (2010 figures) over the past century, leopards may have gained ground. Not only do they prowl through forests – they also sneak stealthily through agricultural land, villages, towns and even major metropolises.
OUT�OF�DATE THINKING Those who believe wild animals ought only to live in wilderness areas doubt that leopards and humans can co-exist peacefully. Surely these predators do not belong in farmland and urban parks where they are likely to cross paths with hapless humans? India’s Forest Service, conservationists and public certainly thought so in the past, and many still do today. Wildlife managers feared that leopards roaming fields meant nothing but trouble, so caught them for release in reserves. Sometimes, to prevent a feline exodus, they also introduced captivebred deer as prey and dug water holes in the forests. 38
BBC Wildlife
For years, few considered what became of these relocated animals. Most assumed that they were relieved to get a lift to their old homes and settled down happily ever after. If any leopards attacked people, disturbance in forests and lack of prey or water were reckoned to be the causes. But in the early 2000s, for no apparent reason, leopards suddenly turned on humans in rural Junnar, in the Pune district of Maharashtra state. They killed 18 people and injured 33 more between 2001 and 2003. Junnar valley was no wildlife tourism destination – it was a fertile valley of sugar cane, bananas, corn, onions and cauliflowers. There were no forests as far as the eye could see, not even on the low hillocks on the horizon, and the only large animals here were cows, sheep, goats, pigs and dogs. Satellite maps of preceding decades showed the landscape had not altered for 20 years, so it was not clear why the leopards’ behaviour had changed. Then wildlife ecologist Vidya Athreya, who lived near Junnar at the time and now works for Wildlife Conservation Society India, discovered that the state’s Forest Department had trapped leopards from farmland and released them in forest areas. The numbers were staggering: between 2001 and 2003 it trapped leopards on 103 occasions within 4,300km2, the size of Northamptonshire and Leicestershire put together.
Leopards often visit villages in Assam, north-east India, but this one was sadly killed by local people.

An innovative scheme called ‘Mumbaikars for Sanjay Gandhi National Park’ helps residents on the outskirts of this city forest in Mumbai to live with leopards, by addressing their legitimate concerns about large predators prowling their apartment complexes. The project has organised better rubbish collections, provided a bus service for children who would otherwise have to walk to school through tall grass, and installed streetlights at strategic locations. The result is that the big cats and people are less likely to encounter each other. O Visit www.mumbaikarsforsgnp.com
The cats were set free in two wooded areas 40–65km away – a small forest in Malshej Ghats, and the larger Bhimashankar Wildlife Sanctuary. Leopards trapped in neighbouring districts were also released in the same locations. Overzealous forest officials were taking the strategy of dealing with leopards living among humans to a whole new level.
DEADLY MISTAKES Above: officials transfer an adult male to Nagaland Zoological Park, Rangapahar. Right: another photograph of the leopard in the inset picture on p36, before it was caught by the Forestry Department.

This project had tragic and unforeseen consequences, unleashing a bunch of cats. They attacked humans within a region the size of Greater London, close to the forests where they had been dropped off. “It’s puzzling why leopards started attacking people in a region that had seen few incidents prior to the largescale translocation exercise,” says Athreya. “Perhaps it was down to the stress of being displaced.

URBAN LEOPARDS 5 REASONS WHY LEOPARDS FLOURISH CLOSE TO PEOPLE
1
DIET Leopards will eat almost anything, from insects to frogs, calves and deer, and they are also scavengers. Though Indian cities seldom support many deer, they do have booming populations of stray dogs and feral pigs because of inefficient waste removal. These are a ready source of prey.
2
HABITAT Provided there is shelter, leopards can use a wide range of landscapes – forested as well as open, and wet as well as arid. India’s farmland offers plentiful cover in the form of dense stands of tall crops such as banana trees, sugar cane and corn. In urban areas, parks and rocky hillocks with caves provide safe hideaways.
3
PROTECTION Since the 1970s, India’s wildlife legislation has outlawed the killing of leopards. This represents a reprieve from campaigns in the 19th century, when the cats (along with tigers, wolves and other predators) were declared vermin and poisoned, trapped or shot. In some parts of India, leopards and tigers are venerated.
4
ADAPTABILITY Leopards are remarkably adaptable animals. Often diurnal in forests, they will switch to a completely nocturnal lifestyle in villages and towns. Being solitary hunters that prey on a variety of small and medium-sized animals, they’re able to maintain a lower profile than tigers or lions despite living among humans.
Above: a varied diet enables leopards to live close to human settlements in farmland or on the fringes of cities. This individual has killed a large spotted deer stag.
5
TOLERANCE This is arguably the most important factor. Even where there is a happy combination of abundant prey, shelter and protective wildlife laws, these adaptable cats still cannot thrive if their human neighbours feel that the danger they pose is too high.
Imagine seeing a leopard on your roof! The cats regularly stray into Mumbai parks and gardens from the adjacent Sanjay Gandhi National Park.

where leopards lived in farmland without coming into conflict with humans. This area looked no different from Junnar. In the early morning men drove motorbikes laden with milk canisters down dirt paths, children walked to school past marigold fields and groups of women in bright saris crouched on the ground laughing and chatting as they weeded vegetable plots. And a short distance away, hidden by a thick curtain of sugar cane stalks, leopards slept, often on their backs with their legs in the air. By fixing GPS collars on two leopards, a male and a female, Athreya studied their movements. While hunting among people, not once did these cats mistake an adult or child for prey. The leopardess gave birth to cubs in a sugar cane field within 100m of a school’s entrance, where hundreds of children ran back and forth on weekdays. The leopard wandered through the school’s courtyard at night when silence ruled. But these were not quiet-seeking country leopards. They were at home in the bustle of Akole. While humans slumbered indoors, these leopards lounged on rooftops, watching the streets and bylanes below for stray dogs and feral pigs. They often made their way to the market in the town centre, where fishmongers and chicken vendors

URBAN LEOPARDS
BIG URBAN PREDATORS WORLDWIDE
BLACK BEAR Black bears raid rubbish tips and fruit trees in the urbanised northeastern USA and the western states of Montana and Colorado. Meanwhile Anchorage in Alaska is known for both its black and grizzly bears, which may be seen rummaging through dustbins on the outskirts of town, while the remote Canadian town of Churchill is popularly called the polar bear capital of the world.
COUGAR
HYENA
Mountain lions, often known as cougars in North America, are the same size as leopards with a similarly catholic diet. Wiped out across the continent over preceding centuries, they are now steadily gaining ground and are increasingly seen crossing suburban roads. One even frequented Griffith Park in Los Angeles; others have been spotted outside Baltimore and Washington DC.
Spotted hyenas range across much of sub-Saharan Africa and about 1,000 are reported to live in Addis Ababa, the Ethiopian capital. Since they scavenge anything even vaguely edible, people tolerate them as walking waste disposal units; they also prey on stray dogs and cats. Another species, the brown hyena, lives near urban centres in southern Africa, such as Johannesburg.
threw fish heads and offal at the far corner of a patch of open ground the size of a football pitch. Clouds of dust rose as pigs and dogs fought over the stinky mess, unaware of leopards watching the melee. But few townspeople saw these large predators. Much to Athreya’s amusement, camera-traps snatched images of the secretive animals in places where people insisted no leopards lived. But livestock owners in the outskirts knew of the predators. They herded their stock through the day and secured them in sturdy barns for the night, not giving leopards a chance at a free meal. Indeed, by studying the cats’ scats, Athreya found that more than half of their diet consisted of domestic dogs and cats, even though goats were seven times more numerous.
FARMERS SECURED THEIR LIVESTOCK IN STURDY BARNS AT NIGHT, NOT GIVING LEOPARDS A CHANCE AT A FREE MEAL. 42
BBC Wildlife
In cases when farm animals do get taken, most Indian states recompense the owners. To put this unique situation in perspective, a high density of people (266 per square kilometre, according to the 2011 census) live in the same area as a large number of leopards (five per 100km2). By comparison, the Chilla mountain range of Rajaji National Park in Uttarakhand state, where there were no people, no farmland and few tigers, had a density of nine leopards per 100km2.
PLAN FOR PEACE Leopards are the most adaptable of cats. As long as their human neighbours do not raise a big fuss, they can thrive across diverse Indian landscapes while people go about their daily lives. We just have to remember that. During the 19th century, the British colonial government declared tigers and leopards to be vermin, December 2014

Two researchers at India’s Nature Conservation Foundation, MD Madhusudan (‘Madhu’) and Sanjay Gubbi, won a prestigious award from the Whitley Fund for Nature in 2011 to study the factors influencing human– leopard conflict in the south-west state of Karnataka. The researchers are using GPS collars to understand how leopards captured in well-populated areas and released into more natural habitats respond to such translocation, which is widely used as a conflictmanagement tool in Karnataka. The project also encourages the media to provide less sensational accounts of encounters with leopards, and runs a public-awareness campaign, distributing pamphlets and posters to over 200 villages. “We should never forget the devastating cost that some of our poorest people pay for wildlife conservation,” says Madhu. “So it’s crucial to get local people on board.” O Visit www.ncf-india.org and www.whitleyaward.org

offered bounties and employed people to wipe them out. Today extermination is out of the question, for leopards enjoy the highest level of protection under Indian wildlife laws. Meanwhile keeping farmland leopards in captivity and giving them a decent quality of life there is prohibitively expensive, and as we have seen moving the big cats can cause deadly problems. So the inevitable conclusion is that people, both in the countryside and the suburbs, have to live with leopards. There is no other option. The good news is that it’s possible to do so with little conflict. While the risk of a runin with a wild leopard is never zero, if people are careful the chances can be kept low. As Athreya says, “The Akole area is not always peaceful, but the local residents – like people in most parts of India – are rarely antagonistic.”
EASY LIVING The question is whether people in other parts of India with different cultural backgrounds, such as Assam, Tamil Nadu and Kashmir, can be convinced to live with leopards. “Humans and leopards are probably managing this more peacefully than we give them credit for,” smiles Athreya. “Sadly conflict is the dominant discourse in the media today, so as readers we focus on the most negative form of interaction between the two.” Researchers can help by focusing less on conflict and more on neutral interaction. Athreya adds, “The media need to help people live with these animals, and forest departments need to change their management from reactive to proactive measures, where sympathetic dialogue with locals is crucial.” Authorities have now stopped moving leopards around at Junnar and Sanjay Gandhi National Park. A decade after the deadly attacks of the early 2000s, the predators have returned to both places, and the big cats and humans manage to share the neighbourhood once again.
PEOPLE HAVE TO LIVE WITH LEOPARDS. THE GOOD NEWS IS THAT IT’S POSSIBLE TO DO SO WITH LITTLE CONFLICT.

WILD DECEMBER WHAT TO SEE O NATURALIST SKILLS O DISCOVERIES 4 RED SQUIRREL
Survival skills Like their burlier grey relatives from North America, our native red squirrels don’t hibernate. “Reds are amazingly tough,” says Mel Tonkin of the Scottish Wildlife Trust. “They grow thick winter coats and will be out and about in all but the harshest weather, searching for the lifesaving caches of tree seeds and fungi that they hoarded in autumn. You can still spot their tracks even when there’s heavy snow cover.” This Cairngorms individual eyeballed photographer Jules Cox during a December blizzard so fierce that his camera kept refocusing on the driving snow. Your best chance of spotting a red squirrel in the Highlands this month is to check one of the feeding stations stocked all winter – try the visitor centres at RSPB Abernethy (there’s also a webcam) or the Scottish Wildlife Trust’s Loch of the Lowes reserve.

FALL IN USE OF RHINO HORN CAMPAIGN TO DEBUNK MYTHS SUGGESTS PEOPLE CAN CHANGE THEIR BEHAVIOUR. public-awareness campaign that’s being run in six major cities in Vietnam has reduced demand for rhino horn by 38 per cent, according to new research. The campaign, which aims to debunk the myth that rhino horn has medicinal qualities, is being run by the Humane Society International (HSI) and the Vietnam Management Authority of the Convention on International Trade in Endangered Species (CITES). HSI’s Dr Teresa Telecky said that the success provided a “ray of hope” that measures adopted in consumer countries could reduce rhino poaching in range states. “The results demonstrate that, even in a relatively short period of time, our campaign has succeeded in significantly

altering public perception and influencing behaviour,” she said. HSI surveyed 1,000 people in August 2013, and found that 4.2 per cent of them said that they bought or used rhino horn, while 52 per cent believed it had a medicinal value. A similar poll, carried out one year later, found that only 2.6 per cent of people said they were rhino-horn users, and only 38 per cent believed that it had medicinal uses. CITES secretary-general John Scanlon said that it was a promising start, but 2.6 per cent of 90 million people was still a lot. “There are fewer than 25,000 rhinos left in the wild – a very small proportion of humans can drive a species to extinction,” he added. Tom Milliken, of the wildlife-
trade monitoring group Traffic, praised HSI for targeting women’s groups, children and businesses to raise awareness, but questioned whether demand had been reduced by the stated figures. “They may be rushing to suggest something that is not absolutely demonstrated by this single poll,” Milliken said. HSI and CITES have finished the first year of a three-year campaign to cut the use of rhino horn in Vietnam. The polls did not ask how often consumers took it or in what quantities, and do not therefore indicate the level of demand. James Fair

BADGERS CHIPPED IN BATTLE AGAINST BTB Microchipping could improve our knowledge of badgers.
Badgers in Cheshire are having microchips implanted under their skin as part of Cheshire Wildlife Trust’s vaccination programme. The chips will tell the trust whether an animal has been immunised against bovine tuberculosis (bTB), reducing
the need to revaccinate the badger if it is retrapped. But it also hopes that the microchips will help them build a better picture of where badgers roam. “Of 99 vaccinated this year, 23 have been chipped,” said the trust’s Richard Gardner. “They might tell us how far they range, and help us understand levels of TB – or lack of it – in them.”

he once familiar soundtrack of summer – the gentle purring of turtle doves, the screaming of swifts and the unmistakable songs of cuckoos – is fading so fast that it will soon be replaced by a deathly silence. The latest report on the state of the UK’s birds, just published by a partnership of organisations ranging from the RSPB to Natural England, makes seriously depressing reading: in less than 20 years, we have lost 88 per cent of our turtle doves, 49 per cent of our cuckoos, 43 per cent of our nightingales, 40 per cent of our swifts… and much more. It’s hard enough to look after birds that stay in one place, but even harder to protect those that spend only part of the year in the UK. I’ve been following the progress of a cuckoo called Livingstone – satellitetagged by the BTO, in Scotland, on 21 May 2013 – and in a single year he travelled to no fewer than 20 different countries. He flew to France and from there to Italy, Tunisia, Libya, Niger, Nigeria, Cameroon, Chad, the Central African Republic, Congo and Gabon; then he returned via Cameroon,

Nigeria, Benin, Togo, Ghana, Ivory Coast, Mali, Mauritania, Algeria, Spain and France, before arriving back in Scotland almost exactly a year later. Just imagine trying to keep a world traveller like Livingstone safe. Clearly, much of the blame does lie outside the UK. For example, hunters and trappers in the Mediterranean are obvious culprits.
IN ONE YEAR A CUCKOO CALLED LIVINGSTONE TRAVELLED TO 20 DIFFERENT COUNTRIES. But we must take responsibility, too. As umpteen more reports testify – from last year’s State of Nature to Defra’s most recent analysis of wild bird population trends – there is ample evidence of shocking declines among our resident species, too. I know we need research to identify problems, priorities and solutions. And I know people will say that things are being done. But it’s clearly not enough. What use are reports that merely record the decline – and even disappearance – of our precious wildlife?

SOLVING RIDDLE OF THE PALM OIL BOOM ONCE REGARDED AS THE ENEMY OF ORANGUTANS, PALM OIL IS NOW SEEN AS THEIR POTENTIAL SAVIOUR – BUT ONLY IF IT IS GROWN IN THE RIGHT WAY. JAMES FAIR REPORTS. ne sequence producer Jonathan Clay directed for the BBC Two series Wonders of the Monsoon involved a team of conservationists shooting an orangutan out of a tree. The storyline – in which a female orangutan is, in fact, anaesthetised and relocated out of an isolated forest fragment – illustrates the corrosive impact of palm oil plantations on the Indonesian island of Sumatra. But while Clay wanted the sequence to create an emotional connection for viewers between these rare great apes and our shopping habits, boycotting palm oil is not the solution, he says.
O
`a THE YIELD PER HECTARE FROM PALM OIL IS AT LEAST SIX TIMES HIGHER THAN FOR OTHER CROPS. 52
BBC Wildlife
Most environmentalists these days agree with him, even though palm oil is a huge threat to orangutans and many other species – one quarter of the 1.24 million ha of Indonesian rainforest lost between 2009 and 2011 was for palm oil, and in some areas it was 75 per cent. Palm oil is a vital ingredient in the food and toiletries we buy, but if those products didn’t contain palm oil, it would be something else such as soya or coconut oil. And as leading environmentalist Jonathon Porritt says, “[Palm oil has] a lower environmental footprint than any of its principal competitors.” Or, put another way, the yield per hectare from palm oil is at least six times higher than for other comparable crops. So, instead of calling for a boycott, Porritt (and many others) has been trying to persuade the major growers, traders and endusers to commit themselves to ‘sustainable’ palm oil, so far with limited success. Now, says Richard George of Greenpeace, there is a glimmer of light. Five of the major palm oil traders – the middlemen who buy from the growers and sell to the product manufacturers – have
Orangutans have been one of the species hit hardest by converting rainforest into palm oil plantations.
THE PROBLEM WITH PALM OIL
FORESTS Virgin rainforest is prized by companies wanting to develop a palm oil plantation – timber can provide a source of income while waiting for the first crop.
PLANTATIONS Palm oil plantations are barren monocultures compared with rainforest – some bird species can survive in them, but they are no habitat for large mammals.

AGENDA ANALYSIS
PALM OIL IN NUMBERS
85 %
of all palm oil is grown in either Indonesia or Malaysia. Thailand, Colombia and Nigeria are the next most significant growers.
PALM OIL production has more than doubled since 2000. Roughly 55 million tonnes are produced every year, accounting for about a third of global vegetable oil output.

TRADERS Palm oil trading companies have a huge influence over the industry but are almost unknown – Golden Agri-Resources and Wilmar International are two big players.
Some are going even further – members of the Palm Oil Innovation Group set aside land for wildlife in order to offset loss of biodiversity in a plantation.
FOREST MITIGATION Brazilian company Agropalma, for example, has protected 64,000ha of Amazonian forest to compensate for the 39,000ha where it grows palm oil, and jaguars, tapirs and giant armadillos have all been recorded on this land. “Environmental impacts cannot be avoided in an economic investment,” said director Marcello Brito, “but they can be mitigated against.”

MILLS & REFINERIES The need to process palm oil helps obscure where it comes from, but campaigners say this part of the supply chain could help promote the sustainability agenda.
committed to only sourcing palm oil that has not resulted in the loss of ‘High Carbon Stock’ forest. “They all have deadlines by which they have said they will have eliminated the problem products,” George said. What’s more, these five traders buy and sell more than half of the total global production. Other traders have promised to halt clearances for a year. So while there are a number of uncertainties, including a challenge to the definition of ‘High Carbon Stock’, George is cautiously optimistic that most companies are making a serious commitment.
Conservationists on the ground in Indonesia do not necessarily believe that sustainable palm oil is going to halt rampant loss of biodiversity. Ian Singleton, of the Sumatran Orangutan Conservation Programme, says there is still a lack of transparency about where the major companies get their palm oil from. With the government on Sumatra attempting to open up massive areas in the north to new developments, he said he was “pessimistic about the future of the forests and the orangutans, tigers, rhinos and elephants that depend on them”. From 13 December this year, thanks to a new EU labelling scheme, consumers will be able to check any product for whether it contains palm oil (though it won’t have to tell them if it was ‘sustainable’ or not). But in the end, said Greenpeace’s Richard George, the public can only do so much to save the orangutan. The long-term solution is to make sure that suppliers and end-users are doing the right thing, and putting pressure on them, he added, is the only way that will be achieved.

RUT BENEATH THE SURFACE I was photographing a large red deer stag, who had about 25 hinds with him, at last light in Bushy Park in Surrey when another large male appeared on the other side of the stream. Both stags were roaring furiously, and the first stag entered and crossed the stream to confront the newcomer. Using his height to his advantage, the challenger got stuck in and forced his rival backwards. He then put his head under the water and lifted the other stag up with his antlers. Stag number one broke free, and they went head-to-head with their heads submerged beneath the water for about a minute and a half.
Just as I was convinced that one of them would drown, the original male leapt out of the stream and ran off, leaving his usurper to give an almighty roar and claim his prize – the hinds. I have never seen such behaviour before, and no other photographers I have spoken to have either. Mark Ollett, www.markollett.com Environment editor James Fair says: What an amazing experience.

YOUR FEEDBACK Explode-a-cone Ben Hoare’s article on exploding seedpods (Wild, September) intrigued me, and I was surprised to discover that the cones of Norfolk pines, which grow in some gardens on New Zealand’s North Island, also explode. The cone is packed with tightly wedged, weighty seeds that boast sharp hooks, and they disintegrate with an audible bang. The seeds are flung large distances, so if you’re nearby and one goes off – duck. Bill Gasson, New Zealand
Preventing poaching The claim, in ‘Seven radical ways to beat poaching’ (October), that new “approaches are starting to bear fruit” is just blind optimism. Every 15 hours a white rhino is killed in Southern Africa. Instead of celebrities saying how “jolly cross” they are, they need to shame the users of rhino horn and other products. But even if this happens, members of the Chinese middle classes buy rhino horn because it’s expensive, not because it inflates sagging libidos – just as people purchase foie gras because it lets them brandish gastronomic badges of honour. Meanwhile range-state countries need to adopt a shooton-sight policy for poachers. Tourism is vital because where you have tourists, you have eyes, and the animals become a meal ticket for many, not a few. Decreased levels of poaching in Nepal coincided with the return of tourists, while the oldest elephant in Tsavo was taken just after the Foreign Office issued an absurd warning on travel to Kenya.

BRAY WATCH I’ve been traipsing up and down Bray Head, on Valentia Island off the coast of County Kerry, in search of whales since I was 13 – always with no luck, though I’ve seen plenty of smaller cetaceans. Finally, in July this year, my fortunes changed. Strong winds had once more appeared to have thwarted my quest, but just as I was packing up our gear my father saw a huge splash north of the Skelligs. I swivelled my ’scope, and saw a humpback whale launch itself out of the swell. It then breached 12 times in 10
Your article highlighted the need to understand economics if poaching is to be beaten, yet failed to explore the impact of destroying seizures of illegally traded products such as ivory. Neither the Convention on International Trade in Endangered Species (CITES) nor the wildlife-trade monitoring group Traffic can point to any analysis of the impact of this policy. By analogy with the trade in other banned substances, destroying contraband simply pushes up the rewards for those who manage to evade the law. Until there is real evidence that destroying confiscated ivory helps wild elephants, surely it makes more sense to stockpile it? John Burton, World Land Trust
Harrier plan There is genuine conflict between hen harriers and red grouse (A Brush With Nature, October), but science has shown that if you lose red grouse shooting, you lose both hen harriers and the incentive to manage heather moorland.

Richard Mabey has revealed what is wrong with conservation in this country. No matter what we do, we are banging our heads against a brick wall because the Government is cap in hand with the moorland owners, and with this status quo there are not going to be any changes in how our uplands are used. Maybe it is time we took our uplands into public ownership and ‘rewilded’ them (as George Monbiot has suggested). Or, failing that, the National Trust, RSPB and other conservation groups should band together and buy huge swaths of hill and moorland to protect them. Oliver Craig, Edinburgh

Reducing marine litter I recently helped get balloon and lantern releases banned by my local council. I assembled a document quoting the views of organisations such as the British Veterinary Association and the WWF. With input from the Marine Conservation Society (MCS) and the National Farmers’ Union, councillors voted unanimously to ban these damaging releases in future. There is a wealth of information out there. The MCS has a ‘Don’t Let Go’ campaign, and Surfers Against Sewage has just released its own Marine Litter Report. Contact your council and insist they consider a ban: it’s a small decision with huge consequences. Paul Vates, Chesham

I agree with Mark Carwardine about captive dolphins (September). I have been swept up in the euphoria of SeaWorld. It was not until later that I thought of the dire lives that captive dolphins must lead. Then, on a boat trip in New Zealand, I had the thrill of watching dolphins play close to the boat and swim with people in the water. There were no trainers to make them perform, and so it was a far more humane way for us to interact with them. Jacqueline Daley, Stockton-on-Tees

t’s still pitch-black as we leave the Veal Krous tented camp near the village of Dongphlet. As we walk into the clearing where the hide is located, Sophoan Sanh, our guide, signals for us to be quiet.“If we make too much noise, the vultures won’t come for their breakfast,” she says with a smile. Sophoan works for the Sam Veasna Center, the Wildlife Conservation Society (WCS) partner in Cambodia. We heed the advice and take up our positions inside the hide, which is dug out of the ground so that we can see the action at eye-level. At around 6am the whoosh of a very large bird passes low overhead, followed by some flapping and an evil-sounding hiss. I risk parting the reedy screen a few centimetres and notice that the sky has lightened slightly, revealing the silhouettes of several vultures at the top of a tree. Much closer, just 30m away, several of these giants are already jostling with each other on the ground. As the sun comes up over this corner of the northern plains of Cambodia, not far from the Laos border, the diners’ identities are revealed. Most are Asian white-rumped vultures, but there are also a handful of red-headed vultures with their strangely perplexed expressions. The latter seem to spend most of their time standing around doing very little, but
they are clearly one step up in the pecking order. Then come the slender-billed vultures with their black, snake-like necks, perfect for pushing deep inside any dead animal. Screams, hisses and the sound of wings flapping… this is the accompaniment to the end game as the bones of a cow are stripped of their last morsels of flesh.
FEEDING TIME Over the course of the next couple of hours I counted 51 white-rumped vultures. As recently as 1985 this magnificent species was described as being “possibly the most abundant large bird of prey in the world” – there may have been 40 million of these natural waste-disposal units in India alone. But now there are only a few thousand left. Has there been a more dramatic avian collapse since the demise of the passenger pigeon? Yet at the Veal Krous vulture restaurant, the high drama of these scavenging birds ripping apart a carcass is still a frequent event. “One of my favourite memories here,” says Sophoan, “is watching at peak feeding time as the three gangs of vultures competed with each other, when suddenly a golden jackal chased them away and took their place.” White-rumped vultures favour light woodland, often very close to human habitation, and roost and nest colonially in tall trees. “Like most December 2014

vultures, the white-rumped is not fussy whether the carrion it eats is fresh or putrid. And they’ll devour any maggots, too,” says Johnny Orn, the charismatic director of the Sam Veasna Center. “A group was once watched picking clean the bones of a bullock in 20 minutes flat.” Smaller numbers of slender-billed and red-headed vultures participated in the Veal Krous feast. The former is a species of dry, open country, usually away from villages, and joins communal roosts but is a solitary nester. “It is subordinate to white-rumpeds at carcasses, so seems to turn up in bigger numbers when its relatives are not around,” says Johnny. The third member of the triumvirate, the red-headed, is classed by the Zoological Society of London as an EDGE species, which stands for ‘Evolutionarily Distinct (with few close relatives) and Globally Endangered’. This species does not roost in large groups, and breeding pairs are strongly territorial. During filming for BBC Two’s recent documentary series Wonders of the Monsoon, cameraman Barrie Britton noticed that each vulture directs aggression almost exclusively at members of its own species. “The vultures would often wade through a melee of feeding birds just to pick a fight with a particular member of their own species,” he says. “The red-headed ones seemed to change the brightness of their heads – they became a more vivid red when they were trying to intimidate rivals, while the slender-billed vultures had particularly impressive threat displays, bending their wings back to expose the white undersides.” Despite their behavioural differences, all three species have been virtually extirpated. It is now well documented December 2014
that the collapse in vulture numbers on the Indian subcontinent – down by a staggering 99 per cent since the mid-1990s – was brought about by the use of diclofenac, an anti-inflammatory drug administered to prolong the working lives of domestic animals (see box). Describing the situation in India before and after the drug took its toll, environmentalist Tony Juniper commented on an RSPB blog: “Each year the vultures were eating about

DICLOFENAC A KILLER DRUG Diclofenac is a non-steroidal antiinflammatory drug developed in the 1970s as a treatment for arthritis and sprains in humans, but it has also been used as a veterinary medication. In the 1990s it began to be widely administered to sick livestock in India, Pakistan, Nepal and Bangladesh. However, when the animals died their carcasses retained the diclofenac, so that when vultures ate the flesh it caused kidney failure, gout and death. The Indian government finally banned its veterinary use in 2006, and Pakistan, Nepal and Bangladesh followed suit. But five years after the Indian diclofenac ban it was
still available in 36 per cent of the country’s veterinary pharmacies, and consignments meant for humans were illicitly diverted for use in cattle. Nevertheless vulture populations have started to recover in some areas. Meanwhile an alternative drug, meloxicam, has been found to be an effective painkiller in cattle and does not kill vultures.

12 million tonnes of rotting flesh. With the vultures gone this became food for wild dogs. Their population rocketed and more dog bites and human rabies infections followed. This in turn led to an estimated 50,000 or so more deaths than would otherwise have been the case. The cost of this and other consequences on India’s economy was (over a decade or so) put at an eye-watering US $34 billion.” Cambodia’s vulture populations had gone into freefall long before the advent of diclofenac in India, reflecting the collapse in the country’s megafauna during decades of internal strife and war, and more efficient animal husbandry that produced a cleaner countryside. Shortly before the Indian vulture crash, Cambodia held only a small proportion of the world’s multi-million-strong populations of Asian white-rumped, red-headed and slender-billed vultures. Yet that is no longer the case. In fact Cambodia stands almost alone in having vulture populations that have stabilised. But it is not just an Asian problem. In Africa, too, diclofenac is hitting vultures hard, and they also face other serious threats on that continent. According to French ecologist Jean-Marc Thiollay, in the West African countries of Burkina Faso, Mali and Niger there has been a 98 per cent decline in the population of four large vulture species in the space of just 35 years. Big falls have also been noted in East and Southern Africa. Mass poisoning and other persecution, habitat change and declines in large ungulate populations

have all played their part. Diclofenac has also been licensed for veterinary use in Spain and Italy, two of Europe’s key countries for vultures. Diclofenac may yet be banned in the EU, but in the meantime this gives vulture conservation in Cambodia, where the drug has never been an issue, some global significance. If these birds become extinct in places such as Dongphlet, what hope is there anywhere else?
SLOW BUT STEADY RECOVERY The Cambodian Vulture Conservation Project was created in 2004 to co-ordinate the activities of several agencies, including BirdLife International’s Cambodia Programme and the Sam Veasna Center. Seven vulture restaurants were established, the first of which was at Veal Krous, and an annual census programme was launched to monitor population trends of the three Critically Endangered species. A cow is slaughtered regularly at each restaurant to supplement the vultures’ diet. In June 2004 the census showed 42 red-headed, 90 Asian white-rumped and 25 slender-billed vultures attending the stations, a total of 157 birds. Six years later the respective figures were 46, 201 and 42, giving a combined total of 289. The restaurants were clearly working. The researchers also monitored vulture nest sites and feeding stations, carried out health checks on the birds, and interviewed government officials, hunters and wildlife traders to collect data on threats. Satellite transmitters were attached to some birds to assess their ranging patterns. “Results from vulture censuses over the past several years have been encouraging, with new nests recorded and even population increases,” says WCS biologist Tom Clements. “With continued investment,

IBIS RICE HOW FARMING CAN HELP TO SAVE A GIANT An innovative agricultural project in Cambodia has created the Ibis Rice brand, giving a boost to the threatened giant ibis (below), the largest member of its family and sole representative of its genus. Numbers of the giant ibis crashed as a result of hunting, deforestation and the drainage of trapengs (seasonal pools) where it feeds – with a global population of as few as 350 individuals, it is now classed as Critically Endangered. The surviving birds are today concentrated on the northern plains of Cambodia, particularly around the Khmer village of Tmatboey. Here villagers have come to see themselves as stewards of the birds’ future, and are working with the Wildlife Conservation Society and the Sam Veasna Center to grow Ibis Rice, produced locally without draining the seasonal pools, cutting down trees or hunting the ibises. Villagers earn extra money by hosting visiting birdwatchers keen to see this global rarity.

these critical populations can survive and grow.” Even better, the Veal Krous restaurant has become an integral part of the life of the Dongphlet community. “Conservation is important for our next generation,” says Prak Bunthy, a deputy chief of the forest community. The initiative works because the Sam Veasna Center ensures that the village benefits financially from any visitors who come to watch, photograph or film the vultures.
COMMUNITY BENEFITS “There are two ways that we reward the community,” explains Johnny Orn. “Firstly we pay the people who cook for tourists and provide tents, as well as the guides who take visitors to the restaurant and the rangers who protect vulture nests. Secondly we collect $30 from every tourist each time they visit the restaurant. We bank the fees until there is a meeting with all of the villagers and they decide the infrastructure to invest in.” The Sam Veasna Center pays $450 for every cow that is slaughtered. Since the project started in 2008, at least $100,000 has been spent on the Dongphlet community, and about $40,000 of that has come from ecotourism organised by the centre. Everyone benefits, and the Sam Veasna Center is already applying the ethos of community involvement elsewhere in Cambodia, for example by taking birders to see rare Bengal floricans. No one has any illusions that it is going to be an easy task to nurture vulture populations back to sustainability. And there have been real setbacks. Vultures have died after ingesting poison targeted at other species, and there have been cases of deliberate attacks with guns and slingshots. But the local community seems to be totally committed. Prak says, proudly, “We, the villagers of Dongphlet, are determined to protect these amazing birds.” TIM HARRIS is a birder who visited Cambodia’s vulture restaurants in 2013. His most recent book is RSPB Migration Hotspots (£25, Bloomsbury).

his year saw a record number of entrants to BBC Wildlife Magazine’s Camera-Trap Photo of the Year competition. In five years it has grown into the world’s most prestigious recognition of the role that new technology plays in our understanding of the natural world. “After talking to researchers and photographers, we decided to overhaul the competition,” says BBC Wildlife editor Matt Swaine. “We wanted to offer two separate awards: one for the most striking photograph, and another for the image that had done the most to advance our understanding of a species. The entries surpassed expectation.” Our panel of experts viewed an astonishing 877 images that made the final cut. Among them were an Amur leopard discovered outside its known range in China, whitelipped peccaries displaying ingenious behaviour in Peru and a European lynx feeding on its prey in Switzerland. “The judging process was tough, but we had an exceptional panel of judges,” adds Matt. “With photographers Mark Carwardine and Elliott Neep, scientist and mammal expert Steve Harris, the expert eye of our picture editor Wanda Sowry and the experience of Rosamund Kidman Cox, we were well equipped to take on that challenge.” You can go online to see more of the entries, but here are the finalists. After much deliberation, the judges reached a unanimous decision in awarding the £3,000 prize to our Overall Research Winner: the image of an Iranian cheetah on p73. We are delighted that this money will go back into research and help the funding for this project. Our thanks go to our sponsor Lowepro for supporting this award. And though competition was fierce, this striking image of a black rhino in Zambia was finally named our Overall Photography Winner.

For more than 10 years the Frankfurt Zoological Society (FZS) has been successfully reintroducing them to North Luangwa National Park. During the early dry season in June 2013 I was working with FZS to track and photograph some of these incredible animals. Rhinos often use the same trails through the bush and frequent the same feeding areas and water holes, so I set up my camera-trap in a clearing that this rhino regularly visited and left it there for about a week. I composed the shot so it would incorporate the starry sky and got this special night-time image. www.burrard-lucas.com

This mule deer was seeking refuge in deep snow on a windswept ridgeline on the Snowy Range, Wyoming. This photo was taken at dawn in March 2014, but the camera was actually set up to try to capture a cougar. Walking this ridge, I had found several sets of cougar prints leading to a place with melted snow, blood and deer hair – clear evidence of a kill site. So I set up my camera in a rocky area that animals travelled through along the ridge. This picture of a mule deer walking past at dawn was the first in my photo set. Later a family of cougars came by, and during the next six weeks I discovered three more kill sites.
In this image a male goitered gazelle is showing aggressive behaviour towards a female in Miandasht Wildlife Refuge, a reserve in North Khorasan Province, north-east Iran – gazelles often compete over water sources in the desert in summer. This picture was taken in August 2012 by Iran’s National Cheetah Monitoring Program, run by the Iranian Cheetah Society, in partnership with the Iranian Department of Environment, the Conservation of Asiatic Cheetah Project and Panthera.

This image was taken at the end of the dry season in August 2012 at a mammal clay lick on the reserve of the Manu Learning Centre, operated by The Crees Foundation. Threatened white-lipped peccaries are known to drink from the water pools and soft clay that gathers in the lick, but in this photo the larger individuals are breaking up the alkaline rocks and clay to eat. This behaviour introduces alkali to the water pools, which neutralises the toxins contained in the food a peccary eats and also allows other species to have access to essential salts. www.crees-manu.org

Bdelloid rotifers reproduce asexually.
WORLD WITH NO MALES Sex costs a lot of energy, so why not evolve to bypass it altogether? Well, one group of animals has. Bdelloid rotifers (the ‘b’ is silent) are tiny creatures found in bird baths, ponds and puddles. When wet they come to life and hoover up micro-organisms. When conditions become dry again they shrivel up into a ball and are blown from place to place. There are billions of them on Earth, and every single one is female. According to their DNA, they haven’t had sex in perhaps 40 million years. Without mixing up their genes through sex, the rotifers should fall prey to bacteria and viruses, their defences outmanoeuvred. Yet they are still here. How? It seems that drying up then blowing from place to place may allow them to outflank and outlast their parasites. In their world, males add no genetic value.

EGGSTRAORDINARY Reproduction using eggs and sperm is like a lottery. Some species hope for success by investing in thousands of cheap tickets, whereas others buy fewer tickets that offer a safer return. Fish are some of the world’s most frivolous gamblers. Among the most prolific vertebrate egg-layers is the ocean sunfish – it’s believed that the female produces as many as 300 million eggs in a single spawning event. The largest eggs in the world are also produced by fish. Whale shark pups hatch from enormous egg capsules within the mother’s body. Each capsule measures over 30cm long, and females may produce more than 300 at a time. Interestingly, a whale shark’s diet is rich in the freefloating eggs of other fish species.

PANDAS ARE GOOD AT SEX Giant pandas are widely chastised for being unable to ‘get in the mood’ in captivity, and for having a window of ovulation (about 36–48 hours) too tiny to be practical. The reproductive life of Edinburgh Zoo’s Tian Tian and Yang Guang shows just how difficult it can be to encourage the species to breed normally in captivity. But in the wild, pandas are masters of sex. Even though their territories can be enormous, males and females locate one another at exactly the right time for ovulation, primarily by monitoring chemical sex messages left on trees via squirts of urine. They also communicate
vocally. Males bleat when they approach a reproductive female, possibly offering an opportunity for her to assess his size and strength. A female in oestrus often mates with several males, so they have evolved one of the highest sperm counts of all bears, to better guarantee any offspring is theirs. As our understanding of the animal’s wild breeding improves, zoos adapt accordingly. For example, keepers liberally apply the urine of potential partners to panda enclosures in the run-up to breeding season. However, the use of ‘panda porn’ or ‘panda Viagra’ is much more controversial.
3+ GIRLS WHO ARE BOYS

Many animals, especially fish, switch between egg-producing (female) and sperm-producing (male) phases during their lives. For instance, in many reef fish all of the juveniles are females and become males as they grow. These are known as ‘sequential hermaphrodites’, a phenomenon very common across a number of taxonomic groups.
«
The Spanish slug can lay up to 400 eggs a year.
In invertebrates, particularly slugs and snails, things go a step further – individuals possess male and female genitalia at the same time. In fact many slugs and snails even have the ability to fertilise their own eggs. With such flexible reproductive equipment, it’s no surprise that a number of invasive species are hermaphroditic. Among the most worrying is the Spanish slug, which has become a serious agricultural pest across much of Europe. A single egg transported in a flowerpot is all it takes to unleash this master and mistress of sex into new places.

ANIMALS HAD SEX ON THE MOON The diversity of mites’ sexual behaviour is staggering. There are mate guarders, harem keepers, warring males, macho show-offs, incest and cannibalism. Perhaps the most celebrated of all is the red velvet mite. Males create trails of silk in their territories that direct females to little packages of their sperm, called spermatophores. If one approves, she
will absorb the sperm into her body. Species of mite are everywhere – in the noses of seals, on the legs of chickens, in the ears of porcupines, in the middle of a sea urchin and within the rectums of bats. In fact it’s likely that eyelash mites Demodex spp. are having sex on your face right now.

SINGING GENITALIA The variety of male genitalia in the animal kingdom is jaw-dropping. There are fin-like ones (sharks), barbed ones (cats, beetles and dragonflies), regenerative ones (seaslugs), lobes (turtles), hooks (mosquitofish), finger-like extensions (barnacles) and a detachable swimming penis (the Argonaut octopus). Some penises have become adapted for other sexual purposes. The lesser water boatman (right) frantically rubs its penis against a special comb-like structure on its body to pump out a mating call equivalent to almost 100dB. Relative to size, it’s the loudest animal on Earth.

THE VALUE OF DIY
One of sex’s greatest mysteries is why so many animals seek to pleasure themselves, rather than find reproductive opportunities with others. Lions, bats, walruses, warthogs, whales, dolphins and deer are just some of those known to partake in such ‘auto-eroticism’. Are such behaviours evolved, or are they emergent phenomena associated with something else, such as captivity? The marine iguana is one species where auto-eroticism is common – smaller males rub themselves against rocks as they approach reproductive females. The behaviour means that their resultant copulations are shorter, so smaller males are less likely to be interrupted by bigger, burlier rivals. According to research, the strategy is likely to increase their chances of a successful mating by 41 per cent – easily enough to Small marine iguanas level the be evolutionarily playing field with significant.

MONOGAMY IS HARD TO FIND
6. Pete Oxford/FLPA; 7. Erica Olsen/FLPA; 8. Brandon Cole/NPL; 9. Alamy; 10. Domingos Rodrigues
Monogamy rarely flourishes in animal groups because fidelity limits an individual’s reproductive potential. It only persists among the species where the result is a higher number of healthy offspring. In birds, where the raising of chicks may demand care from both parents, monogamy arises fairly frequently. But it has popped up in other species and groups, too: antelopes, prairie voles, some cichlid fishes and the Australian sleepy lizard (also known as the shingleback skink). None of these are true monogamists though – each may be inclined to change partners between seasons. Though many consider swans, albatrosses and emperor penguins to be nature’s most virtuous couples, all of these pale in significance compared with Eurasian bullfinches and jackdaws. Bullfinches are highly monogamous, and as a result males are modestly endowed and produce poor-quality sperm, not having any need for more sophisticated reproductive mechanisms. On the other hand, jackdaws remain faithful for life and stay near their partners year-round, even within bustling and complex colonies. They are perhaps the most monogamous of all common UK birds.

HOMOSEXUAL ACTS ARE WIDESPREAD Though animals rarely eschew sex totally with the opposite sex, observations of individuals partaking in homosexual activities throughout their lives are wonderfully common, from hyenas, lions, whiptail lizards, dragonflies and bed bugs through to orcas, koalas, barn owls, king penguins, mallards, sticklebacks and rattlesnakes, to name but a few. According to the experts, bottlenose dolphins indulge in homosexual activities as much as heterosexual activities. One of their favourite activities is ‘goosing’, when dolphins of the same sex nudge each other’s genital slits with their beaks. Other bottlenoses indulge in ‘socio-sexual petting’, when homosexual and heterosexual pairs stroke one another’s undersides with their outstretched flippers. Only in recent years have scientists begun to lift the lid on the evolutionary causes that may be responsible. Though homosexual animals in vertebrates obviously suffer from lower reproductive outputs, there may be evolutionary benefits such as kin selection, whereby non-reproductive offspring enhance the survival and reproductive chances of their siblings, ensuring their own family genes persist.

DUCK DRAMAS Being largely internalised soft structures, female genitalia can be tricky to study. Among the best understood are ducks’. Intense competition between male ducks has done remarkable things. They have evolved a long corkscrew penis that can be ‘exploded’ into a female’s reproductive tract, giving a male a greater chance Mallard sex than his rivals of successful is often a fertilisation. In response the rough affair. female reproductive tract has evolved into an anti-corkscrew, with pockets and dead ends. By modelling the tract of Muscovy ducks, scientists found that she can rebuff unwanted sperm – her reproductive passages only loosen enough to grant access to the males that she deems worthy. They’re the ones with the brightest bill, for those are most likely healthiest and less likely to be infected with sexually transmitted diseases.
SUPER-SPERM Just as natural selection chisels animals into all sorts of shapes and behaviours, it also works on their sperm. Famously members of the fruit-fly family have some of the longest sperm in the animal kingdom: those of Drosophila melanogaster are visible to the human eye, being almost 2mm long (about 40 times longer than our sperm), while other species have sperm cells an order of magnitude higher. Why do fruit-flies invest in such lengthy sperm? The female’s lengthy and convoluted reproductive tract (itself only slightly longer than the sperm) may be the reason, or long sperm could be an adaptation to block the sperm of rival males.
FATAL ATTRACTIONS Episodes of sex that are so intense the animal dies, known as semelparity, evolve when it pays more (in terms of offspring) for males and females to invest everything in one sex act than to stay alive and breed again next year. The Pacific salmon is a good example. Though not strictly semelparous, frogs and toads often live their last days during the breeding season. The energetics of mating are arguably worse for females than males – competition can be so intense that she drowns under a mass of rival suitors. But when this happens in the frog Rhinella proboscidea, death doesn’t spell the end – the males practise ‘functional necrophilia’, squeezing eggs from dead females which they fertilise in the water.

O
n a warm, clear and windless day in July my three colleagues and I gingerly descend the 100m drop from the top of the island into one of its main guillemot colonies. The beauty of this location is that for most of the climb the masses of birds cannot see us. They continue with the business of brooding and feeding their well-grown chicks. We set up our temporary camp out of sight at a traditional site behind some boulders and start to unpack our equipment: pliers, green-netting Brussels sprout bags, a carbonDecember 2014
fibre fishing pole, hundreds of heavy-duty colour rings each engraved with a unique number, and circlips for opening the rings. This is our annual visit to catch and ring several hundred guillemot chicks and 50 or so adult birds. I have been doing this for 42 years here on Skomer Island, south-west Wales, and the purpose is to keep this longterm study of the guillemot’s biology going. Only by having individually recognisable birds can we accumulate the information that allows us to understand how Skomer’s guillemot population works. When I started in 1972 there were just
2,000 pairs of guillemots, but since the mid-1980s the population has increased to about 25,000 pairs. Success at one level, but a far cry from the 100,000 pairs that were on Skomer’s cliffs in the 1930s.
KNOWING THE NUMBERS Like most other seabirds, guillemots lay one egg so their potential rate of increase is low, and they are long-lived, with an average breeding life of 20 years – our oldest guillemot on Skomer is a male in his early 30s. By knowing how long birds live, how many chicks they produce and when they BBC Wildlife

There are 950,000 breeding pairs of guillemots in the UK, 25,000 of which are on Skomer.
SKOMER’S GUILLEMOTS 10 THINGS TIM’S STUDY REVEALED 1 7 BREEDING SUCCESS is determined largely by the number of close neighbours. Guillemots breed at high density to deter predatory gulls and ravens that, given the chance, would eat their eggs and chicks.
2
HIGH NUMBERS and high-density breeding give guillemots the confidence to sit tight in the face of a predator. When the population was low in the 1970s, the birds were very nervous; they are much more confident now.
CLIMATE CHANGE also affects the survival of adult birds. Warm, wet, windy winters are becoming more frequent, and are taking their toll. When my study started, no-one had considered climate change and its effects on bird populations.

USING VARIOUS tracking devices, we have been able to see the massive movements Skomer’s guillemots make outside the breeding season – from Portugal to the Faroes – in search of food.

GUILLEMOTS ON Skomer have a high survival rate. About 95 per cent of adults survive from one year to the next, and approximately 50 per cent of chicks that fledge manage to reach breeding age.
THE SKOMER guillemot population is largely self-contained. Young birds usually return to breed there, sometimes close to where they hatched. Immigration seems to be rare: one bird ringed as a chick in the Baltic moved to Skomer to breed, but that’s unusual.
GUILLEMOT CHICKS on Skomer are fed mainly on energy-rich sprats; elsewhere in the UK they are fed sandeels. But in 2014 Skomer birds were catching more herring and cod-like fish, which may signal a change in the ocean, probably not for the better.
THE INCREASE in numbers since the mid-1980s (see p83) is good news but fragile. Elsewhere in the UK, guillemot breeding success is generally very low and populations are decreasing.
5
GLOBAL WARMING resulted in progressively earlier breeding between the 1970s and about 2005 – an advance of roughly two weeks. More recently, the breeding seasons have flipped between the earliest and latest in 42 years. Could climate change be to blame?

THE FOUR major oil spills of the past 40 years, including three hundreds of kilometres from Skomer, resulted in a doubling of the annual adult mortality rate.

Tim discovered that guillemots usually return to their natal colony to breed.
The longer you study birds (here Bristol’s urban gulls), the more valuable your data.
first breed we can predict which way the population is heading. One of the hardest parameters to obtain is the survival of young birds: the proportion of the chicks that fledge that live to become breeding adults. Since most guillemots don’t start to breed until they are seven, and some not until they are 10 or 12, a long-term study is essential. It is also essential for other reasons: the environment isn’t static. Keeping a long-term study going for 40 or more years is not a trivial undertaking. Most of the Research Council grants that fund scientific research in Britain last only three or sometimes five years. Of course it is possible for researchers to acquire successive grants, but that’s far from certain, and even less certain during an age of austerity. Uninterrupted funding is what all long-term studies need. The plight of those engaged in longterm studies is made worse by the fact that governments and grant-awarding bodies want a quick return for their funding in the form of scientific papers. It requires considerable ingenuity to simultaneously produce spectacular short-term science as well as solid long-term research. Given the difficulties, why do researchers work so hard to keep their long-term studies going? The answer, as every biologist will December 2014

Our lives – both biologically and politically – are now dominated by shorttermism, quick fixes and superficiality. Many biologists I know pursuing long-term studies will admit that if they had stopped after three or five years, they’d have got it wrong. They recognise that both expertise and understanding increase exponentially year on year. They also acknowledge that the long view allows you to see that, far from being stable, the natural world is subject to all sorts of changes including, in the case of seabirds, climate change and overfishing. It is the desire to really get to grips with a biological system that gives researchers the willpower and tenacity to keep their long-term studies going. Projects spanning December 2014

Initially this meant giving them numbered metal leg rings, which was fine for easily captured (and recaptured) species such as tits or pied flycatchers that will breed in nestboxes. Indeed, the longest-running study, of great tits in the Netherlands, began in the 1930s.

It was John Coulson, while studying kittiwakes at Durham University, who discovered the perfect material – a robust plastic made by what was then ICI, named Darvic. Darvic came in different colours, could be easily cut and moulded to fit any seabird’s leg, and wasn’t much affected by age or sea water. Birds were given either a combination of colour rings or a single ring engraved with numbers or letters to identify them.

On Mandarte Island ornithologists have built up one of the most comprehensive pedigrees for any bird, linking parents and offspring back over 25 generations. It reveals how genes and the environment can work together to influence the sparrows’ lives.
Peter and Rosemary Grant’s study of Darwin’s finches has provided, among other things, the most convincing demonstration of natural selection in the wild, by looking at the birds’ bill size before and after extreme environmental events caused by El Niño.

“LONG-TERM STUDIES LET US ANSWER NOT JUST THE QUESTIONS WE THINK ARE IMPORTANT NOW, BUT OFTEN QUESTIONS THAT BECOME IMPORTANT.” Rosemary Grant’s wonderfully informative study of Darwin’s finches on the Galápagos. A list like this, and it isn’t complete, gives the impression that there are lots of longterm studies. But my guess is that for every long-term study on birds there will have been several hundred short-term ones. The important point is that long-term studies are often disproportionately successful in terms of the quality and quantity of scientific publications they generate. As Ben Sheldon, who now manages the long-term great tit study at Oxford, says: “The unique value of long-term studies is that they enable us to answer not just the questions we think are important now, but often also the questions that become important.” Tim Clutton-Brock at Cambridge, who runs long-term studies of red deer on Rum and meerkats in South Africa, adds: “There are many ecological processes that can only be detected by data spanning several decades – and many important biological and ecological questions that can only be answered with long86

term records of the life histories of individuals. Studies that can provide access to data of this kind are a vitally important research source for future generations – and their maintenance should be a priority for funding bodies.”
FUNDING ISSUES The Grants’ long-term project exploring Darwin’s finches spanned 40 years. Unless, as in the case of the Oxford great tit study, one can find both funding and a successor, 40 years seems to be about the limit of long-term studies. This in itself tells us that the success of such endeavours is strongly affected by the drive and enthusiasm of individual researchers. The Grants have now retired. Will anyone continue their work? Who will inherit their database? We simply don’t know. Long-term studies can also come to an end for reasons other than retirement. In some cases, the funding may simply run out, as happened with my study of guillemots on Skomer. This was especially
unfortunate because it coincided with the ‘wreck’ that killed thousands of guillemots, and unless I can find an alternative source of funds we will never benefit from a full understanding of the consequences of that massive additional mortality. Still, I’m hopeful. And I look forward to my visits to Skomer next year with my research assistant to search for colour-ringed birds to see who has survived the winter storms; to measure their breeding success; and to place rings on the legs of a new generation of chicks so that we – or someone else – can follow their fortunes for another 40 years.

How wild is a domestic rabbit?
MIKE TOMS
A
Since rabbits were domesticated relatively recently and in an identifiable location (1,400 years ago in southern France), they make ideal candidates for genetic research. Scientists from Uppsala University, Sweden, have explored the differences between tame rabbits and their wild genetic neighbours by sequencing the genome of a domestic individual and comparing it with that of its wild cousins. Domestication is a result of many small changes in the brain and nervous system, rather than domestication genes. A key one is reduction in flight response – pet rabbits face fewer threats. They also discovered that tame rabbits rarely completely lose their wild genes, which suggests they could become ‘genetically wild’ again if released. Karen Emslie

Do whales have heavy bones to help them sink? A
It’s reasonable to assume that whales and other cetaceans would have heavy bones to counteract their huge amounts of fatty, buoyant blubber. However, there is in fact considerable variation in the skeletons of marine mammals. Generally speaking, bottom-feeding marine mammals such as dugongs and manatees tend to have dense, heavy bones to help them stay down, while surface-
feeding cetaceans, such as plankton-feeding baleen whales, have a low bone density, making them ‘positively’ buoyant and helping them to float. Cetaceans that spend their time moving up and down through the water column, such as dolphins and porpoises, are halfway between the two, so are ‘neutrally’ buoyant, ascending and descending with minimal effort.

Why don’t conifers shed their leaves? A In the tropics trees continuously replace old leaves with new ones year-round, but at higher latitudes winter brings the risk of frost damage. This is why many species drop the lot in autumn and replace them the following spring. However, this is a costly strategy in terms of the nutrients lost in the fallen leaves, so species that grow on poorer soils, including most conifers, hang onto their precious foliage throughout the winter. The small surface area and waxy outer coating of needles provide some protection against frost, but even this may not be enough at the highest latitudes and altitudes. This might explain why the larch, a deciduous conifer, appears to buck the trend. Stuart Blackman 90

Q
B I O L O GY
Why are big organisms rare? A
There are several answers to this. The first is simply that the earliest organisms in any group tend to be small, and remain small – only a few evolve larger sizes. The second is that large organisms take a lot of energy to maintain. So they require larger spaces to live in, and competition with other large animals will ensure that there are fewer of them. The third is that larger creatures often run into problems of heat loss and support not suffered by smaller animals. Yet a fourth is that larger animals tend to have fewer offspring, keeping populations small and survival precarious. The fifth is that once they have become big, they need a huge standing stock of smaller creatures to feed on. It’s no wonder that the biggest creatures evolve in the sea – where the territories are vast, and problems of support and heat loss are minimised – and graze on enormous quantities of plankton that are further down the food-chain and easy to harvest.

HOW TO
STEP 1
PHOTOGRAPHY
I wanted to introduce a temporary hide to the edge of this sea loch on the Isle of Skye that I could use to photograph shorebirds. To decide on the location, I sat with the equipment I would be using to check range, perspective and lighting, then put the hide at the foot of a bank and beneath the skyline.
MAKE YOUR OWN WILDLIFE HIDE long telephoto lens alone doesn’t guarantee successful close-ups of wildlife – good fieldcraft is often crucial. Aside from careful stalking, using some form of hide can make a big difference. The permanent wooden hides common to nature reserves can be effective because wildlife becomes habituated to them, but the downside is that they are often never quite close enough, or in locations that provide a general view over likely habitat rather than targeted at anything specific. The alternative is to improvise or purchase a ready-made portable hide, or build something more permanent yourself. Portable fabric hides come in various guises and have the advantage that they are freestanding, lightweight and quick to deploy. Choose one that is shower-proof, of a colour matching the habitat in which you will be using it, and made from material heavy enough that your silhouette won’t be seen when the sun is behind you. You should also be able to secure it to the ground so that it won’t flap around. But the main thing is that your shelter is large enough and comfortable enough for you to spend a lot of time there: the longer you wait, the more you will see. Laurie Campbell
lauriecampbell.com
A
STEP 2 I added the canvas cover over the free-standing frame of the hide, then put stones in pockets sewn inside the hem along the bottom. These would keep the fabric stable and improve its waterproof qualities. I also moved a few rocks into position around the hide to reduce its profile in the landscape.
STEP 3 Lastly I added scrim netting and seaweed that I found cast up on the upper shore. This amount of camouflage is rarely needed solely for the animals’ sake, but another reason I use it is to conceal my hides from the public so I can avoid unwanted attention and disturbance.

Q
BIRDS
Why are robins so tame? A
British robins readily associate with gardeners, but elsewhere in Europe they are shy and retiring birds of thick woodland cover. It may just be because continental robins, the migratory northern populations of which winter around the Mediterranean, have long been exposed to hunting in the southern part of their range, leaving the species particularly skulking in its habits, while in Britain we do not share the tradition of trapping and shooting small birds. Why other British birds are less confiding than the robin may be linked to feeding behaviour. Robins take most of their food from the ground, including invertebrates disturbed by larger animals. They may view us in a similar way, as they scavenge worms unearthed by the gardener’s spade. This behaviour persists because they have nothing to fear.
Robins may seem friendly, but they are aggressively territorial towards their rivals.

Why do webs have ‘signatures?’
The wasp spider creates a web with a very visible zigzag.
December 2014
A A few spiders, notably the wasp spider Argiope bruennichi and conical spider Cyclosa conica in the UK, include a conspicuous streak or zigzag of pale, woolly silk through the middle of their web. But the meaning of the ‘signature’ is still open to debate. Though called a ‘stabilimentum’, it has nothing to do with stability and species across the world build stabilimenta in spiral, cross and ribbon forms. In Cyclosa it may well hide the spider, which further decorates the silk with its own moulted skins and prey remnants. Some of the more elaborate signatures may act like warning signs, preventing birds colliding with and destroying the web. Richard Jones Entomologist

What will I find if I go pond dipping in winter? A You can find plenty. Dragonfly nymphs, damselfly nymphs, a host of water beetles, water boatmen, backswimmers, water hoglice, leeches, mayfly nymphs, caddis fly nymphs – all of these creatures overwinter in ponds, and are active and easily visible on even the coldest days. In fact, for many aquatic invertebrates winter is an important time for growth in preparation for their crucial breeding endeavours in spring. There’s even an argument that pond food-webs become reenergised in winter, aided by the increased oxygen content (cold water retains more oxygen) and the influx of dead leaves in autumn on which detritivores flourish. Some ponds may also contain overwintering tadpoles, a phenomenon that might be more common than we imagine. In particularly mild winters adult amphibians continue to be active too – I have seen newts hunting in the water in mid-December. However, during colder wintry spells frogs may retreat to the depths where they sit motionless, breathing through their skins. So if you do go dipping, don’t disturb them.

Why is bird excrement white? A
The droppings produced by birds contain materials from the excretory (urine) and the alimentary (faeces) systems, a result of the two emptying into the cloaca, where the reproductive system also has an opening. Whereas the faeces contain undigested food remains, and so tend to reflect the diet in general composition, the urine is

responsible for the white appearance seen in many bird droppings. The urine produced by birds varies widely in appearance, but is usually cream-coloured. It contains a high concentration of urates – the salts or esters of uric acid – and whitish crystals of uric acid are deposited after some of the water has been reabsorbed in the cloaca. It is these crystals that give the droppings their white appearance. The whitest droppings tend to be produced by seabirds and it is these, rather than those of other birds, that may be correctly termed guano. Some species, such as cormorants, use guano as a nesting material. MT

Which animal is fastest for its size? A This record is currently held by a Californian mite Paratarsotomus macropalpis, which races along at an average of 192.4 body lengths per second, though a top speed of 322 body lengths per second has been clocked. To achieve this feat it takes 135 steps every second.
In contrast, Usain Bolt manages roughly 5.3 body lengths per second over 100m, while a cheetah at full pelt reaches about 18 body lengths per second. Were Mr Bolt to match the mite’s top speed, adjusted for size, he’d travel at 2,295kph and manage 100m in 0.16 seconds. SB 3

OVERCOMING THE ODDS LIFE STORY BBC Books, £25.00
ccompanying the BBC One series presented by David Attenborough, Life Story is a coffee-table tome about the struggle for success that begins for every animal at birth. As his foreword states, “There is just one goal – to leave offspring, the next best thing to immortality.” Mirroring the six-part series, the book, by executive producer Mike Gunton and series producer Rupert Barrington, charts the journey from first steps to parenthood, uncovering the often herculean challenges along the way: learning to hunt, dispatching rivals, making homes, finding mates. The behaviour is astonishing (the archerfish that nails its prey with a deadly jet of water), mesmerising (the peacock jumping spider that waggles to impress the fairer sex) and heart-wrenching (the tiger cubs struggling against habitat loss and poaching). A selection of enjoyable makingofs from the 78 expeditions fill the final chapter – from creating an entire underwater studio to film one little fish, to scrambling up a scree slope without starting a landslide.

All shapes and sizes are represented – from a T. rex and an ichthyosaur to a perfectly preserved Discoglossus frog and microscopic coccoliths (plates of calcium carbonate formed by single-celled algae). In their authoritative text palaeobiologists Paul Taylor and Aaron O’Dea explore the background of the specimens, revealing what the Earth was like when each of them was alive, the social history of the person who found it, and how the fossil has improved our knowledge of the species concerned. I especially liked hearing how Helicoprion, a shark-like creature, flummoxed scientists for over a century with a mouth containing a spiral of serrated teeth. The result is no mere ID guide for fossils, but a beautiful and very readable portfolio providing fascinating insights into some of the best-kept secrets in palaeontology.

If David Attenborough is your hero, his inspirational memoir of over 60 years in broadcasting is a must-read. He’s a witty, self-effacing raconteur, generous to colleagues but ready to poke fun at bureaucracy, at one point noting drily that the early BBC voiceover work that launched his career was “Staff: No fee”. In this updated edition he includes the years since 2009, relating with Tiggerish enthusiasm the advances that are transforming wildlife TV, from helicopter-mounted Cineflex cameras to CGI, 3D and filming from drones. The only thing left to invent, he says wryly, is smelly-vision.
In this very readable book, the third in the British Wildlife Collection series, Nigel Holmes and Paul Raven navigate us expertly through the turbulent natural history of UK rivers. The authors’ writing is as lucid as a chalk stream and crammed with nuggets: did you know that marsh marigolds can bloom underwater, or that the scales of the freshwater fish bleak were used to make artificial pearls? The final chapter tackles our modern relationship with rivers with inspiring examples of restoration and improvement. If you have any interest in current natural history or conservation, this beautifully illustrated volume is a must.

THE NAMING OF THE SHREW
TALES FROM GOMBE By Anup Shah and Fiona Rogers
Bloomsbury £25.00
NHM Publishing £40.00
Living such different lives from ours, roaming the oceans in all weathers and mostly visiting land only to breed, the subjects of this timely book have a romance and mystery that make them so special. Britain and Ireland are rightly famed for their wealth of seabirds, but until now we have lacked an up-to-date popular account. This book fits the bill admirably, and naturalist Marianne Taylor does an excellent job of providing evocative and informative descriptions of every species that occurs or has occurred around our shores. The text is greatly enhanced by the superb photographs, most of them by David Tipling.
Almost 55 years of research at Gombe has helped uncover the workings of chimpanzee society. From tool use to mother and child bonds, they have taught us not only about great apes, but also what it means to be human. Anup Shah first visited Gombe in 2003 on assignment for National Geographic magazine, and he returned with his wife Fiona Rogers for a three-year project to capture this intimate portrait of the members of the main dynasties. Their fine photography and observation skills do justice to the chimps’ lives, full of passion, drama, ambition and love.

Why do we use Latin names?
For science, a single stable name is essential for all of the species it studies. Common names are great but unstable. There are also far, far too many of them for any one species, and most organisms have no common name at all. So is naming a species after a famous person bad for science?
Eponyms – names borrowed from people – are often fun: Scaptia beyonceae, a horsefly blessed with a perfectly round and golden rear end, comes to mind. They are extremely common and go back to zoologist Carl Linnaeus who used them to honour friends. However, they tell us nothing about a species, and I for one prefer descriptive names. What is the most misleading Latin name you’ve come across?
A surprisingly high number are absurdly misleading. My favourite is Lichen aromaticus, which has no smell at all. The lichen was sent to the taxonomist who named it in a perfumed envelope. BBC Wildlife

is a witty tribute to the history and construction of the Latin names that catalogue our natural world.
Many find scientific names offputting, but beneath their stern exterior there is history, scientific and etymological sense, and often a great deal of fun. The subject is as much about people as it is about the natural world, providing endless tales of triumph and disaster.

Though the format may be familiar, close encounters with this subspecies are not – this is the first time arctic wolves have been filmed in such proximity. It’s also the first time this pack has ever had contact with people, their closest human neighbours comprising a small Inuit community more than 300km away. “It’s like going back to the Garden of Eden,” says series producer Ted Oakes. “Wolves are very misunderstood predators, persecuted worldwide and often demonised in feature films. This series gives a privileged insight into their true nature. It’s also a huge challenge for Gordon to overcome his fear and understand how their minds work.” As it happens, the wolves take to the presenter well, even trusting him to ‘cub-sit’ while they go off to hunt.

ATTENBOROUGH’S PARADISE BIRDS Due to air in January – check RT for details.
ince the first specimens were brought to Europe in 1522, birds of paradise have captivated explorers, artists, naturalists and film-makers across the globe. Among them, famously, is David Attenborough, who presents this one-hour special. It’s a film he has wanted to make “for 40 years”. David’s passion for this extraordinary group of birds was ignited at the age of 10, when he read Alfred Russel Wallace’s The Malay Archipelago. Though Wallace may have been the first European to witness the courtship display, Attenborough was the first to film it, during a Zoo Quest expedition in 1957. Delving into the BBC archives and art collections, this is a fascinating blend of nature, history and history
S
of art. Attenborough reveals how the birds’ dazzling plumes quickly became prized by collectors and sought by royalty (hence their often grand common names); examines the early attempts to illustrate the creatures with only flat, dry, legless skins for reference (limbs were removed for preservation, the traders claiming that the birds were godly creatures that sipped dew from the clouds); and looks at the successes of film-makers over the years, from his own early efforts to the US team who have just managed to capture all 39 species on film. “He goes back to the very start of our knowledge and understanding of these birds,” says producer Miles Barton, “and shows how far we’ve come in the few hundred years since.” SM BBC Wildlife

t was raining puffins. They filled the air like a swarm of irate bees, buzzing about the 100m basalt cliffs of Garbh Eilean and peppering the sea surface, as well they might. The Shiant Isles, just off the Isle of Harris, are one of their main British colonies, with perhaps 10 per cent of our breeding population. The birds may have been an impressive welcoming committee, but they weren’t what we’d come for. We wanted to see black rats, the notorious distributors of the bubonic plague. The species has colonised much of the world by stowing away on ships, and the Shiants are no different – except that this population is the last substantive colony in the British Isles. In the summer months the rats prey on the eggs and chicks of nesting seabirds, which is likely to be their downfall. Following a successful eradication programme on Lundy, RSPB Scotland is embarking on a similar one here using poisoned bait at a cost of £900,000. But the move is controversial. The birds are doing extremely
well, and the rats have shown no sign of spreading. Arguments about whether they are non-native or assimilated persist, but the fact is that they’ve been at large in Britain for more than 1,000 years. They are bound up in our cultural heritage for good or ill, and my friends and I wanted to see them before they are gone forever. We were not travelling light. Besides our usual arsenal of optical and photographic equipment, we had camping gear, portable lamps, night scopes, more than 50 live traps and plenty of bait. As we unloaded onto the small beach, we must have resembled a film crew from the BBC’s Natural History Unit. There’s only one building on the Shiants, a tiny cottage on the other island of Eilean an Taighe. We laid traps around the cottage, set up bait stations at one end of the stony beach connecting the two islands and waited.
We wondered how long it might take (we had enough food to last several days), but within an hour a trapdoor snapped shut, and we rushed over to see what we’d caught. The trap held a fine black rat, and that was only the beginning. Several rats of varying shades of charcoal emerged from the shadows and raided our bait, reflective eyes blazing in our torch beams as we watched in awe. More entered the live traps overnight, too. It was smiles all round the following morning as we collected up our gear beneath the watchful gaze of a visiting white-tailed eagle above. To us the rats were much more than pests. As we left the islands the same seabird spectacle that had welcomed us the previous day bade us farewell. Despite the proliferation of rodents we’d witnessed during the night, it was clearly business as usual at the seabird colony. It was still raining puffins – the perfect end to our oncein-a-lifetime encounter.
