Swans will usually protect their nests and family fiercely, but this group of mute swans are so used to having people around them that visitors can get up close to newly hatched cygnets Abbotsbury Swannery in Dorset, England, is the world’s only managed nesting mute swan colony. For centuries over 100 pairs have flocked to the lagoon for breeding season, and every other year they’re rounded up for a health check by people in canoes.

At maturity, males develop a set of large canine teeth and the characteristic patch of grey hair down their backs. A silverback decides where the group goes and uses his size and strength to keep the troop safe from harm.

Swallowing its own feathers, the horned grebe builds up a filter in its stomach that holds bones until they’ve been digested, allowing it to safely eat fish whole as it dives for food In winter the only colour on the horned grebe is its red eyes. Come breeding season, however, both sexes sprout a tu of yellow feathers behind each ear. Horned grebes catch insects flying over the water and use their large feet to swim down in search of fish and arthropods.

Keeping cool While we can break out the fans, iced drinks and air conditioning, animals have had to come up with more creative ways of coping when they start feeling the heat Words Victoria Williams

Keeping cool
Blood circulates through a butterfly’s wings, and the large surface area acts like an elephant’s ear to maximise heat loss on hot days.
Acting shady For many animals, the best way to cope with heat is simply to avoid it Some animals – known as ectotherms – are unable to regulate their body temperature internally. These species have to use the heat of the Sun to warm themselves up but then need to change their behaviour before they overheat. Lizards, toads and salamanders will dig themselves into dirt, sand or leaves in search of cool patches, while butterflies and dragonflies can use dark patches on their wings to shade their bodies if they’re in a sunny patch. If that’s not enough, they’ll take off in search of shade, which brings the added benefit of a cool breeze. As a mammal, the Cape ground squirrel is able to control its temperature to an extent, but it still folds its bushy tail over to use it like a parasol under the hot African Sun.

Keeping cool
Getting sweaty It’s our main method of thermoregulation when we get too hot, but sweating is rare in the animal kingdom When we get too hot, we sweat. As the liquid evaporates from our skin heat energy is drawn away from our body. Some animals, like cats and dogs, sweat a little between the pads of their feet, but heavy perspiration is something we only share with monkeys, apes and horses. A horse’s primary method for cooling down is panting, and its long nose makes it an efficient mechanism when it’s at rest or moving slowly. When it’s galloping at high speed, however, panting is no longer effective and it starts sweating.
It’s thought that sweating allowed early humans to become endurance hunters, just as it lets horses travel at high speed over long distances. While we perspire for the same reason, the composition of our sweat is different. Human sweat is almost entirely made of water and salt, but a horse’s sweat glands secrete a mixture of water, fats and proteins – this protein-rich recipe seems to help it lather and flow past the animal’s thick waterproof hair to the surface where it can evaporate.
No sweat For those that don’t perspire, there are alternatives
Many animals wade, but few seem to relish their time in the water quite as much as the moose. Moose have been known to stand in water for hours at a time, enjoying the chance to cool down.
They don’t sweat, but kangaroos are able to produce a similar effect by giving themselves an elegantly named ‘spit bath’. They lick their forearms to cover them in saliva, which then evaporates in the heat of the Sun.
If you thought a spit bath was bad, you won’t like the alternative to sweating used by storks and turkey vultures. It’s called urohidrosis, and it involves the birds releasing their waste all over their legs.

Just like us, horses have armpits packed with a high concentration of sweat glands.

Keeping cool Sleeping through it Aestivation – the hot weather equivalent of hibernation – is just as critical in extreme heat
Playing it by ear Along with the elephant, several animals rely on their ears to help them keep their cool
Snails By sealing the opening of their shells with mucous and slowing their metabolism, land snails can avoid drying out when a hot spell arrives.
An elephant’s ears are one of its most famous features, but they’re not just there for decoration. Jackrabbits, fennec foxes and elephants all have highly sensitive hearing, but thermoregulation is likely to be the main reason they evolved huge ears. These animals live in harsh climates, and their big ears provide a vital service in hot weather. The large, thin areas of skin are full of blood vessels running
close to the surface. If things start to get uncomfortably warm, the vessels dilate – muscles relax so blood flow near the surface increases, maximising the amount of heat lost from the blood to the air. This tactic is especially useful in the desert as it doesn’t cost any valuable water. Elephants waft their ears back and forth and spray them with water to enhance the effect.
“Thermoregulation is likely to be the main reason they evolved huge ears” Fat-tailed dwarf lemur The fat-tailed dwarf lemur is the first primate found to aestivate, spending up to seven months avoiding hot weather in a dormant state in a small tree hole.
Water-holding frogs Filling their bladders with water, burrowing underground and secreting a mucous cocoon, this species can stay dormant for over five years.
West African lungfish The strange-looking lungfish has a primitive lung as well as the usual set of gills and survives heat by digging itself into mud.
Ladybirds Ladybirds in hot regions congregate and undergo summer dormancy as plants dry up and the number of sap-sucking insects drops.

Jackrabbits are actually hares, not rabbits. The first part of their name comes from ‘jackass’, a reference to the similarity between their ears and those of a donkey

By combining water and flapping, elephants can cool the blood in the vessels of their ears by as much as ten degrees Celsius (50 degrees Fahrenheit).

Keeping cool
Breathing it out With all their exuberance and energy, dogs need a way of getting rid of heat as quickly as possible If you’ve ever been around a dog on a hot day or after an enthusiastic game of fetch, you’ll have seen it panting. Sticking their tongues out, dogs will pant quickly to expel hot breath and replace it with cooler air. It’s a behaviour they share with foxes, wolves and coyotes, but there are some surprising species that pant too, including cats, birds and rodents.
Lizards don’t exactly pant, but they do use their mouths to lose heat. From tiny reptiles up to huge crocodiles, all will sit with their mouths wide open in a behaviour called gaping. Reptiles are ectotherms, relying completely on external factors to control their body temperature, so after basking in the Sun to warm up they can gape to stop themselves getting any hotter.
“Sticking their tongues out, dogs pant quickly to expel hot breath and replace it with cooler air”
18
A dog normally takes around 20–40 breaths in a minute, but this can increase to 400 when they’re panting heavily.

Having a flutter
Taking a mud bath From piglets to rhinos, some animals wallow to keep their bodies comfortable
They might not have big ears to flap, but these birds have a neat trick up their sleeves – or rather, down their throats – when the weather is warm
Warthog Some animals, like warthogs, will choose mud over a splash in clean water. The moisture in mud takes longer to evaporate from the skin, leaving the animals feeling cooler for longer.
Pig Pigs only have a few sweat glands, but they are not much use for dissipating heat, and they’re almost completely unable to pant. They can only cool down by finding shade and wallowing in mud.
Rhino Wallowing does more than just keep animals cool; a good coating of mud provides a natural sunscreen and deters parasites. Sumatran rhinos spend hours a day wallowing to keep their skin healthy.
Water buffalo Splayed hooves allow water buffalos to wade through mud in search of the best patch before they submerge themselves. Domestic buffalo are taken to wallows to rest during the hottest part of the day.

For some birds, panting just isn’t enough; species including owls, doves, nightjars, pelicans and herons ramp up their efforts to stay cool with a tactic known as gular fluttering. Opening their mouths, the birds vibrate the muscles inside their throats. Similar to the flapping of an elephant’s ears, this movement exposes the moist membranes within to the air and encourages cooling by evaporation. Although it might look like a lot of effort, the vibrations are small and don’t use much energy. For birds that roost in the open and are constantly exposed to sunlight and high temperatures, gular fluttering is a lifesaver.

Restoring South Georgia’s birdlife

RESTORING SOUTH GEORGIA’S BIRDLIFE The South Georgia Heritage Trust and the Habitat Restoration Project team tell us how they were able to rid an entire island of invasive rats in just over a decade Words Rachael Funnell ground that at its peak played host to over 2,000 human residents. From the arrival of Cook, predatory brown rats (Rattus norvegicus) began to exploit the groundnesting behaviours of the island’s native birds, causing devastation to their populations for over 200 years. Commercial whaling came to an end in 1966, but the threat posed to the island’s birds remained, with brown rats by now an established species on South Georgia. In 2005, the South Georgia Heritage Trust (SGHT) was founded to conserve indigenous flora and fauna, as well as the island’s historic heritage. As concern grew for the future of the Georgia pintail and South Georgia pipit, which doesn’t exist anywhere else on Earth, plans for an ambitious

The island of South Georgia was once a haven for wildlife living on the edge of the harsh Atlantic waters. Untouched by humans, it provided shelter for fur seals, elephant seals, two species of endemic land birds and a wealth of seabirds. All this changed in 1775 when the island was discovered by Captain Cook, the adventurous British explorer immediately recognising the sealing and whaling potential of the island. Soon, hunters from across the globe were flocking to South Georgia to exploit the abundant resources. Each boat brought with it a chance for opportunistic stowaways to invade, and soon the island was infested with rats. Once an uninhabited oasis, South Georgia was now a rich hunting
21
Restoring South Georgia’s birdlife Habitat Restoration Project began in 2008 with the aim Rattus norvegicus of returning the ancestral Class Mammalia habitat to the island’s native wildlife. Mike Richardson, trustee of SGHT and chairman of the Habitat Territory Worldwide Restoration Project Steering Diet Omnivore Committee, explains. Lifespan 2 years Adult weight 140–500g “The main culprit was (4.9–17.6oz) the brown rat, which is Conservation Status a nuisance and a vermin but also a very voracious predator. One of the most LEAST CONCERN adaptable and successful animals on the planet, it can live virtually anywhere and eat virtually anything. On the island of South Georgia, where there isn’t such a thing as trees, all the birds are either nesting on the ground or in burrows, meaning their chicks are very vulnerable to such predation.” As the SGHT began planning Phase I of their fourstage approach, the first consideration was the unique geography of South Georgia. Long and narrow in shape, it is a mountainous and glaciated landscape consisting of two ranges – Allardyce and Salvesen – which form the backbone of the island. This protects the northern-facing habitats from adverse weather, which sweeps in from Antarctica to the south and Drake Passage to the west. Three-quarters of the island is covered in glaciers and snowfields, which creates a geographical barrier meaning populations of rats, while prevalent, were isolated. BROWN RAT
“The great thing about South Georgia is that it’s broken up by ice fields and glaciers, which act as a barrier to rodents going laterally along the island,” explains Mike. “So, what we had to deal with was a number of islands within the island, which meant that we could sequentially bait in different phases or different areas confident in the knowledge that eradicated areas would not later be inhabited by rats from elsewhere.” Unfortunately, these isolated habitats also meant monitoring the island would require a considered approach in order to transport the necessary fieldworkers and equipment to the remote and inhospitable locations. Furthermore, remote teams would require specialist kit to withstand the gruelling conditions that can last for days at a time in South Georgia. “It was an extremely audacious endeavour,” says Mike. “We knew from the outset that it would be a huge project, far bigger than anything that had been attempted before. The Australians had already achieved successful results in eradicating rats from Macquarie Island, but this was roughly an eighth of the size of South Georgia. We would also be dealing with a very hostile environment, and above all we knew we would need an awful lot of money. Eradicating [rats from] an island the size of South Georgia does not come cheap.” Phase I, the trial baiting phase, commenced in 2011 and required two helicopters and 50 tons of bait, which had to be imported from the United States. Each baiting phase would distribute a third-generation rodenticide across the island, executed using a similar technique to spreading fertiliser in agriculture. A hopper containing the bait would

South Georgia’s affected birds Ground-dwelling bird species were the worst affected by the invasion of non-native brown rats South Georgia pipit Anthus antarcticus is a small, groundnesting bird that produces just four eggs per year, meaning the predation of even one is a huge loss. South Georgia pintail Anas georgica georgica is a duck endemic to South Georgia. It nests in tussock grass and is omnivorous, having been witnessed feeding on seal carcasses.
Why are rats so successful? Throughout history rats have been associated with mass devastation, in part due to their sheer numbers. What makes these rodents so prolific?
Rapid reproduction Brown rats reach sexual maturity at five weeks, a er which they can have litters of up to 14 with a gestation period of just 21 days.
Lack of competition On South Georgia, brown rats were free from predation by other land species, meaning their numbers increased exponentially.
Fierce predators Omnivorous brown rats will eat anything, and their affinity for burrowing makes them particularly dangerous for ground-nesting birds.
Highly adaptable Rats are found in every continent except Antarctica, making them one of the most widespread mammals on Earth.

be slung beneath a helicopter with a spinner to project the bait. The width of the area covered in pellets could then be controlled by altering the helicopter’s height and speed. Phase II began in 2013, this time covering a larger surface area and requiring 157 tons of bait. At this time, a workforce of 25 people made up ‘Team Rat’, comprising of four pilots, two engineers, three chefs, two doctors and field staff members. In 2015, the final baiting season was completed. “Each phase was spaced two years apart, in part because we needed to find more money,” Mike explains, “but also to allow us to learn from the experience of the previous phase in terms of methodology and results. After three phases of baiting we knew we had to go back and make sure it had worked. We were on tenterhooks waiting to find out what had been found. Would there be signs of one rat? Would there be an enclave of survivors somewhere in the large area that we tried to eradicate? Or would in fact a whole area now be inhabited by rodents once more?” To obtain the most accurate results, monitoring took place two years after the final baiting phase. In that period of time any small groups of rodents – even just one pregnant female – would have been able to breed up to huge population quantities. Brown rats can have multiple litters in a year, each one giving rise to more litters, which results in exponential population size growth. “To find one rodent is very difficult, but after two and a half years, if

they were there, we were going to be able to find them,” says project director Dickie Hall. The search for evidence of rats involved a combination of detection devices. Passive devices were deployed across the island, the most common of which was a combination of a wax tag, chew board and chew stick. Designed to be an attractant to rodents, they were laced with oils and peanut butter. A sub-sampling procedure was established to identify target areas for monitoring, with 4,600 devices deployed. “Penguin colonies are a huge attractant to rodents for eggs, chicks and dead animals, so we focused on areas that would draw [them] in. If any were to have encountered [a monitoring device] there would have been very clear tooth marks. “We also used more targeted tracking devices such as camera traps and ink boards, which leave footprints if the rodents walk through. Our camera traps captured plenty of footage of fur seals, but no rats.” The active monitoring devices took the form of three ‘sniffer’ dogs trained to detect the presence of rodents and able to catch a scent from tens of metres away. Each dog walked a series of transects in search of signs of rodents, but after six months none were found. The qualitative evidence of the success of the restoration project came in the form of the population boom of native species that followed as Dickie explains. “When we began the eradication, anywhere where there
were rats present the South Georgia pipit generally wasn’t, as they couldn’t nest or breed successfully. Following the eradication, every single site we went to we found pipits – in many cases breeding successfully.” “The sound of calling pipits was now drowning out the roaring of elephant seals,” adds Mike. “The eradication is complete, but this is just the start. As South Georgia begins to return to its natural state, other changes to its ecosystem mean precise change is very difficult to predict, and this should continue to be monitored.” The landscape is changing, with glaciers and ice fields retreating further each year. The most marked difference has been observed in the Neumayer Glacier, which has retreated by a distance of 4.4 kilometres (2.7 miles) since 1957. The significance of this is that, should a rat infestation reoccur, it’s unlikely that a similar eradication effort would be successful again. The future of the native wildlife of South Georgia now rests in the efficiency of biosecurity measures put in place to prevent a reoccurrence. Lord Gardiner, parliamentary under-secretary for the Department for Environment, Food, Agriculture and Rural Affairs, said, “The successful eradication has underpinned South Georgia’s reputation as a jewel in the crown of the British overseas territories, but the focus now moves to biosecurity measures to ensure the 10,000 visitors to the island each year preserve the legacy of South Georgia. “Overseas territories contain 90 per cent of our wildlife, and invasive, non-native species continue to be one of the biggest threats. Enormous lessons need to be learned from what happened [here] and the example of what the SGHT have achieved must be taken advantage of. This restoration has taken South Georgia back to pre-Cook times and is a victory in proving our ability to reverse the effects caused by human interference.”

Natural silk has been produced from silkworm cocoons since around 4000 BCE. It’s a controversial industry because 3,000–6,000 silkworms are killed to produce a kilogram (2.2 pounds) of silk, but the process by which the caterpillars create the fibres is undeniably amazing.

Because manufacturers need the silk threads to remain intact, around 99 per cent of silkworms are killed before they can break out of the cocoon and mate.
1. Eggs Female silkmoths lay up to 800 eggs before dying a few days later. The eggs hatch into small black larvae a er ten to 14 days.
2. Caterpillar Silkworms increase thousands of times in size over five instars (stages), shedding their skin between each one. They eat leaves voraciously to fuel this rapid growth.

From humble garden ladybirds to rainforestinforestdwelling titans, the beetle family includes some seriously impressive species – badass bugs that make other insects look positively puny Words Matt Ayres The rate at which the global human population continues to increase is a serious cause for concern to many scientists, but when it comes to sheer numbers, we are firmly put in the shade by beetles. To put it bluntly, the world is crawling with them – about 400,000 species and counting to be precise. Accounting for around 25 per cent of all known life on Earth, each one is a member of the order Coleoptera, a name that is derived from the Greek words koleos, meaning ‘sheath’ and pteron, which translates as ‘wing’, and while they may be small, they make up for their size in a myriad of ways. These beetles put the ‘bad’ in ‘badass’.

Rhinoceros beetles are as tough as they look. Proportionate to their size, these tough little creatures are ranked among the strongest animals on Earth, able to lift objects over 100 times their own weight. To put this in perspective, a human would need to lift a fully grown African elephant to even come close to matching it. One of the secrets behind the rhinoceros beetle’s brawn is its body construction. Their exoskeletons mean they are built like tanks, with thick armour covering their muscles and bolstering their anatomies.
But it’s not just muscles and armour that make the rhinoceros beetle a force to be reckoned with – males have huge horns that are used for fighting in a similar manner to the mighty mammals they’re named after. They also use their horns for digging, burrowing themselves in the ground to hide from the few predators big and scary enough to eat them. In Japan, gamblers often bet large amounts of money on rhinoceros beetle fights, in which two beetles try to push one another off a log.

Fogstand beetles are one of nature’s most innovative survivors The fogstand beetle is one of the animal kingdom’s most resourceful survivalists. It lives in the Namib Desert in southern Africa, where water is incredibly hard to come by. But where most animals would die of thirst, this unassuming insect thrives, and it’s all thanks to an amazing evolutionary trait. Fogstand beetles collect tiny water droplets from the wind and fog, catching them on their bumpy backs. The small protrusions on the beetle’s body are hydrophilic, actively attracting water to cling to the insect. Simultaneously, hydrophobic (water-
repelling) troughs next to the bumps prevent the collected water from escaping. By standing at a 45-degree angle the fogstand beetle adeptly rolls each miniscule droplet down its back and into its gaping mouth. This phenomenal survival strategy has inspired scientists to look for ways to capture moisture from thin air. Mimicking the beetle’s combination of hydrophilic and hydrophobic bumps has allowed researchers to extract water from the air to create self-filling water bottles in arid regions.

Burying beetles perform bloody burials to benefit their babies Burying beetles are the undertakers of the animal kingdom, named after their habit of burying the carcasses of larger animals. But their burial service doesn’t come for free: the deceased animal becomes a valuable asset for the six-legged gravediggers, who use buried corpses to feed their developing – and utterly ravenous – larvae. Upon finding a suitable carcass, beetles will battle it out to decide which pair gets to use the deceased animal. The triumphant duo will then begin to dig a hole beneath
30
the body. During the burial, the beetles strip the corpse of fur and feathers and use the materials to line the crypt. The dead animal is also covered in an antimicrobial secretion that prevents the body from rotting and attracting other animals. Eggs are laid in the soil around the body, allowing the beetle larvae to emerge and feed on it. Both parents stick around to take care of their young and protect them from competing creatures, a level of care that’s rarely seen among insect species.
Bombardiers mix deadly chemicals inside their bodies While you might think of chemical weapons as a human invention, insects have been using deadly substances to overwhelm their opponents for millennia. The bombardier beetle’s arsenal is a lethal testimony to this fact. These carnivorous creepy crawlies use a noxious chemical spray to destroy any insect foolish enough to attack them. The weapon works by combining two chemical compounds (hydroquinone and hydrogen peroxide) stored in the bombardier’s abdomen. When the beetle
feels under threat it opens a valve to combine the two substances, causing a chemical reaction that raises the temperature of the mixture to near boiling point. It then expels it powerfully through the abdomen with a loud popping sound. The spray irritates the respiratory system and frequently kills predators. Some African bombardier beetles have the ability to direct their chemical spray with incredible accuracy, swivelling their abdomens to aim their natural weapons at a potential threat.

Then there is the ladybird’s ability to emit a toxic fluid through the joints of its exoskeleton. When attacked by a predator the bugs squirt this foul alkaloid substance, sending their assailants flying in search of easier, tastier prey.

Over the next six to seven weeks the developing tadpoles would grow in the female’s gut while she suppressed the production of digestive acids and went without food. Only around half of the offspring survived this process, but when it was time for them to emerge the juvenile frogs came into the world through their mother’s mouth. Unfortunately, herpetologists didn’t have much time to study this behaviour because both species were gone by the mid-1980s. No one knows what caused them to die off, but possible culprits include logging, water pollution, fire and the chytrid fungus. This might not be the end of the story though, because if the Australian scientists achieve their goal the gastric brooding frog might become the first extinct species that isn’t lost forever.

The Jurassic Park-inspired idea of recreating dinosaurs from preserved DNA is a fantasy, but Australian researchers believe they can resurrect the more recently extirpated gastric brooding frog. Scientists have experimented with inserting genetic material from frozen tissues of the extinct frog into eggs of a related species. If they succeed in producing an embryo it will be a fitting milestone in the natural history of an animal that had its own extraordinary reproductive habits. The gastric brooding frog was first definitively identified in mountainous rainforests in southern Queensland, Australia, in 1972. Just 12 years later, a second species was discovered in similar habitats further north. Both southern and northern gastric brooding frogs, as the species were named, lived in rivers and pools and might have hibernated under rocks in winter.

KEEPING JAGUARS Maya the jaguar cub found a loving home when she came to the Big Cat Sanctuary in Kent, but is raising such a powerful wild predator by hand the right way to go? Words Victoria Williams Maya the black jaguar stole thousands of hearts earlier this year when she appeared as the star of BBC documentary Big Cats About The House. Viewers followed every step of her journey as she was hand-reared by Giles Clark, director of the Big Cat Sanctuary in Kent. Giles has decades of experience raising and caring for big cats, so he was the obvious choice when another wildlife facility needed help with a struggling jaguar cub. “By day five mum was paying less attention to little Maya, and they thought, combined with the fact that she was already showing signs of becoming dehydrated, for whatever reason mum was not as engaged as she should have been. Maybe she was aware that something wasn’t quite right with Maya at the time; what happens in the wild is that mums won’t invest energy and resources into a cub that wouldn’t make it anyway.” When it became obvious that Maya wouldn’t make it if she remained with her mother, Giles made a big commitment by agreeing to provide the cub with roundthe-clock care for the next 12 weeks. She was tiny, but the little lady had big demands. “When I’ve hand-reared cubs in the past, very rarely have I had one on its own – it’s either with siblings or I’ve

Keeping jaguars been able to introduce it to another cub of a similar age. Jaguars are very intense anyway, and that’s even evident as a young cub, but being on her own as well meant if she was awake she demanded your undivided attention. It’s quite intense and somewhat repetitive making up formula and constantly meeting all of her health needs, but to look at her now, every second was ultimately worth it.” Maya is now a year old and approaching her full size. Although sharing a home with Giles for her first few months has created a strong bond between the pair, they’re going to have to spend less time together as she becomes a powerful, solitary adult. “We’ve already started to implement a strategy where we are reducing the frequency with which she gets contact, and over the next four to six weeks we will go to completely protective contact with her the same way any other zoo or facility would. If we’d pulled back and stopped going in with her too soon I think it would have caused some anxiety and stress; I truly believe that all baby animals require that intensive level of affection and companionship. As she gets closer to when she would naturally disperse from her mum, hormonally she’ll go through that change anyway and you won’t get that stress. She’ll still have an incredibly close bond with the people that have been there while she was being handreared, but we will start to step up more of the traditional training and conditioning processes.” While most of the responses to Maya’s story were positive, some people objected to the idea of a jaguar

being raised in captivity and believed she should have been in the wild. Giles explained, “I’ve done hundreds of talks and presentations and one of my opening lines is exactly that – in an ideal world I would not want to see animals in enclosures. It’s only because at the moment it’s a complete necessity given the situations that many of these species face in the wild. The reason I chose to rear her in the house was because that’s where I could give her everything she needed, physically as well as mentally. But she’s a wild animal at the end of the day – she has her instincts and I would never want to take that away from her, nor would I be able to even if I tried. I would never suggest that wild animals make good pets.” Since she first arrived at the sanctuary, Maya’s life has been shared with people across the world through social media. Her journey has been an unusual one, but the huge amount of interest she’s garnered could prove to be incredibly valuable for her wild relatives. “What she’s done is help generate this interest by becoming a real ambassador for her species and the wider issues of cat conservation in the wild. She’s far exceeded everyone’s expectations in terms of positive engagement. Thousands of children have been inspired because of her story and are now wanting to engage and further support us or conservation organisations. The amount of times I hear ‘Oh, we

Jaguars face many threats They might only be listed as Near Threatened, but life is certainly not easy for jaguars in the wild
Habitat loss There are currently still large areas of forest for jaguars to live in, but they’re being encroached on more and more as land is developed. If jaguars become isolated, they’ll be unable to find mates. Living her life in the spotlight, Maya has launched a new wave of interest in jaguars and big cat conservation
for the better. “Being a conscious consumer would probably be one of the most important steps that people could make. Talk to people; the more that we can spread the word and create awareness that these species do matter and that they are teetering on the edge of extinction the better. “If you have disposable resources you can support conservation organisations by making a donation or volunteering your time, getting on board and beating that drum.” That is certainly a beat that we at World Of Animals can march to.
“The good news for jaguars is that it’s by no means too late, and I think they could potentially represent one of the true success stories”
Reduction in prey As jaguars lose their habitat, so too do the species that they prey on, such as wild boars, capybaras and tapirs. With smaller fragmented areas of forest and fewer animals, hunting becomes ever harder.
Conflict with humans As their range is reduced and their prey dwindles, jaguars will occasionally take livestock from local farms. To try and protect their animals, some farmers and ranchers harm or hunt down the cats.
Poaching The jaguar’s beautiful coat is one of its most captivating features, and sadly there are people who would rather see it as a rug decorating their home than on the animal, so poaching can be profitable.

didn’t know that jaguars were in that much trouble or big cats were in that much trouble’ and ‘We can’t let these animals disappear’ – that to me is a real testament and is really inspiring.” For some species of big cat, the situation is becoming critical. It’s thought that the jaguar has a healthier population, but they’re still in danger. “Out of the big cats, they are not faring too badly in terms of numbers. At the moment the jaguar is listed as Near Threatened, but that is under review and very shortly that could turn to Vulnerable in terms of their status. We hear numbers all the time and sometimes I think that’s dangerous. I think the true reflection is if you look at the habitat where they used to be in comparison to where they are now – the jaguar, for example, has lost over 40 per cent [of its former range]. “When we talk about saving some of these large carnivores we need to be protecting large-scale habitats, and that’s not easy because the population of humans is ever growing and the demand for resources that causes is also ever growing. A lot of the time jaguars are killed because of human-wildlife conflict, and that’s exacerbated because the population of people continues to climb, and at the same time the habitat is being fragmented and we are putting pressure on their natural prey. The challenge is twofold; we need to save large-scale landscapes that are connected across the range, while at the same time addressing the needs of the communities. “The good news for jaguars is that it is by no means too late, and I think they could potentially represent one of the true success stories when it comes to big cat conservation because they still have that vast chunk of habitat available in South America. In theory, the vast majority of jaguars across their range are still potentially connected via habitat to one another, whereas when you look at a map of a tiger or a lion range you’ll see just how incredibly fragmented that [population] is.” It’s easy to feel helpless hearing that big cats are in such trouble, but Giles believes everyone can make a change

Sloths have enormous stomachs with four separate chambers. The organ takes up most of the space in their abdomen. Bacteria ferment their food, which can take up to a month to digest.

Sloth teeth don’t have enamel and continue to grow throughout the animal’s lifetime. They emerge as cylinders and get their shape as they wear against other teeth.

When they strike, their talons clamp shut with a force that can even shatter bone. To counter this threat sloths rely on camouflage to remain hidden from predators. They keep incredibly still during the day, using the algae in their fur to blend in with the leaves. It’s not unusual for a sloth to spend its whole life in the same tree.

only do they provide highways in the air, they also give the sloths much-needed cover, shielding them from view. However, there’s only so long a sloth can spend hidden in the leaves before it needs to make a trip to the toilet. This involves an arduous trek to the ground. Travelling down makes an eagle attack less likely, but a different set of predators lie in wait on the floor. Central and South America are the hunting grounds of ocelots, pumas, jaguars and anacondas, which can grow to the length of a bus. Sloths don’t move well on all fours, so outpacing an agile cat is impossible. Mother sloths spend around six months preparing their young for the challenges of forest life, but there’s one threat that’s hard to train for – us. We cut down trees, build farms and roads and take young sloths from their homes to sell as bush meat. Sloths are independent animals, but they need joined-up forests so that they can find one another when it’s time to mate. To ensure their survival, we need to protect their trees.

Sloths and humans have a history that dates back thousands of years, back to a time when giant ground sloths roamed the Earth. The largest species – the megatherium – was six metres (19.7 feet) tall and weighed more than an African elephant. They disappeared towards the end of the last Ice Age around 11,000 years ago, and our ancestors may have been responsible for their demise. The sheer muscle power of these animals would have made them a challenge to kill, but traces in the fossil records reveal that humans may have tried. Fossilised footprints uncovered in New Mexico in 2017 show the outline of human feet inside sloth tracks. This means that people followed behind while the mud was still wet. There aren’t any sloth bones with cut marks le by human tools, so we can’t know what happened for sure, but it’s possible that hunters were on the beast’s trail.
All about sloths
The life of a sloth Sloths might move slowly, but there is more to these fascinating animals than meets the eye Sloths spend their lives high in the trees, travelling from branch to branch in search of buds and leaves. Two-toed sloths sometimes like to add some dietary variety in the form of fruit and flowers, but they’re in no hurry to find the perfect meal. Sloths take life at a slow pace, and when they’re not eating they’re usually resting. They move so little that each individual only needs around 0.02 square kilometres (0.007 square miles) of forest to survive. It’s rare to find more than one sloth in a tree, unless they’re getting ready to mate. Sloths wake up after the Sun sets, slow down over night and then become active again before dawn, but they aren’t as lazy as they first appear. A study monitoring brain activity in captive three-toed sloths found that

Why do sloths poop on the ground?
48
Sloths spend their lives in the trees, but once or twice a week they make the slow, dangerous journey to the floor. The reason? They need to poop. Three-toed sloths even dig a hole in the ground with their tail before covering it over again when they’re done. This unusual behaviour puts sloths at risk, bringing them close to ground-based predators like cats and snakes, but they make the trek up and down the tree trunks anyway. Scientists are unsure of the reason, but they have a few possible explanations. One of the most convincing is that sloths can’t get all the nutrients they need from leaves alone. Scientists think that they eat soil when they're on the ground, supplementing their diet with essential salts.
they snoozed for two thirds of the day, but wild sloths were different. They only slept for between nine and ten hours, just a little more than humans. When it comes to reproduction, the males put in extra effort, travelling away from their home range to find a female. Scientists have even spotted them fighting for the chance to mate. They use the hooked claws on their front legs as weapons, sometimes leaving scars on the face of their opponent. For the most part though, the life of a sloth is quiet and solitary. The air in the branches can be cool, and the higher up sloths live, the thicker their fur is. The coat of a sloth has two layers: a warm, fuzzy undercoat close to their skin, and a long, shaggy outer coat that grows upside down and hangs towards the floor. This outer coat
traps water, attracting a whole ecosystem of insects, which use it as a home and therefore depend on the sloth for their survival. One animal can have nearly 1,000 critters living in its fur. These include common parasites like mosquitoes, sandflies and ticks, and an unusual community of beetles and moths. Sloth fur provides a ready-made habitat for these insects, and they’ve evolved together over generations. Scarab beetles burrow into the fur at their elbows and knees, while moths make homes all over their bodies. The insects even lay their eggs in sloth dung. During the wet season sloth fur is often coated with algae, which grows in the cracks on the hair shafts. This may provide a source of nutrition for the insects and even for the sloths themselves.
Love in the air Sloths do almost everything in the branches, including mating and giving birth. Females let other sloths know they’re in the mood for love by making loud calls that attract males from nearby trees.
Ready to go Life in the trees can be hard for a newborn, so sloths are born ready to take up the challenge. They keep a tight grip on mum’s fur and emerge with open eyes and sharp teeth. They start to eat leaves in their first month.
The slow lane Sloths take life’s challenges at a leisurely pace
Having a swim Sloths are most at home in the trees, but they are surprisingly agile in the water. Cameras even captured threetoed sloths swimming during filming for Planet Earth II, revealing that their long limbs make excellent paddles.
Staying safe Sloths don’t have many predators in the trees, so they aren’t well equipped to defend themselves. The biggest threat is the powerful harpy eagle. Sloths keep hidden by staying very still, disappearing from view among the leaves.

Just resting Sloths do most of their moving at night, travelling at the breakneck speed of about 0.2kph (0.15mph). During the day they rest, hanging quietly from the branches without moving at all.

SKUNK AND DISORDERLY Although renowned around the world for their stupefying stench, there’s far more to these misunderstood mammals than meets the nose‌ Words Adam Millward
54
Being known as the ‘King Pong’ of the animal kingdom is a mixed blessing. On the one hand, having such a redolent reputation protects you from many dangers. Often, just the sight of that black-and-white coat and bushy tail is enough to send a potential predator packing in the opposite direction! On the other hand, skunks’ noxious notoriety has also led to their vilification. For many pest controllers they are enemy number one, and people will go to great efforts to deter these creatures from entering their neighbourhood or even eliminate any deemed to have ventured too close to their homes.
There are 12 different species in the extended Mephitidae family, which fall into five distinct groups: striped, spotted, hooded, hog-nosed and ‘stink badgers’. All of these are based in the Americas, bar the last group; stink badgers (definitely skunks rather than badgers, despite their name) reside on tropical islands in Southeast Asia. Skunks are adaptable creatures, living in a range of habitats including woodland, grassy plains, scrubland, streambeds, ravines and even rocky mountain slopes. Many skunks seem to favour ecotones – areas where two types of biome meet, for instance, where a
forest edges onto marshland – most likely because such zones offer a greater variety of food sources. The entire family is, of course, distinguished by its back-end bio-weapon, a pungent secretion that they can fire with surprising range and accuracy to defend themselves against predators. Another family trait are distinctive markings, which, while coming in different patterns and shades, all serve as a clear warning to stay away. For anyone who’s had the misfortune to have been on the receiving end of a skunk attack, you can’t say they didn’t try to warn you!

Skunk and disorderly
What is that smell? How stink helps skunks to stay alive From armour in the form of shells and spikes to weapons such as poison and claws, self-defence is crucial to the survival of many animals on the lower rungs of the food chain. However, few have evolved a strategy quite like the skunk to keep enemies at bay – but that’s not to say it isn’t effective. Quite the contrary! The skunk’s foul spray is a potent cocktail of volatile sulphur-hydrogen compounds, known as thiols and thiocyanates. While the former generate the initial astringent stench that can
induce nausea, tears and even temporary blindness (thiols are also present in raw onion and rotting organic matter), it’s the latter that makes a skunk’s musk so enduring. This is because contact with water in the days – or even weeks – after its release animates thioacetates, converting them into the more pungent thiols. The odour is so pervasive it can be detected more than a mile away. Couple this noxious substance with a precise deployment system and you’ve got a serious weapon.
Anatomy of a skunk
DID YOU KNOW?
Discover how these mammals’ bodies have adapted to keep them safe
Not everyone can smell skunks’ funky bio-weapon. In fact, around one in 1,000 people are immune to it. The serendipitous condition, known as specific anosmia, makes a person unable to detect a particular odour.
STRIPED SKUNK Mephitis mephitis Class Mammalia
Territory North America Diet Birds, small mammals, amphibians, reptiles, fish, eggs, carrion, insects, seeds, grains, nuts and fruit Lifespan 6–7 years Adult weight 1.2–5.3kg (2.6–11.7Ib) Conservation Status
Scent glands The skunk’s odoriferous bio-weapon is stored in two glands in its rear end. Surrounding muscles enable the stinky secretion to be fired over several metres or released as a mist.
LEAST CONCERN
Markings Bold black-and-white colouration is an immediate warning to any passers-by to keep on passing. A skunk’s stripes o en point straight to its back-end, further emphasising the danger zone.
Eyes Many nocturnal animals have superior vision, but shortsighted skunks can only see about 3m (9.8 ) ahead. They rely instead on their senses of smell and hearing.
Sharp teeth A set of 34 teeth, including four particularly pointy canines, means that wild skunks are definitely not for stroking!
Claws Skunks use their strong front feet and elongated claws for digging in search of prey such as grubs and worms.

The musk is stored in two glands at the base of the skunk’s tail. Muscles surrounding these glands give the animal a great degree of control over how the liquid is released; it can either be fired as a stream towards a specific target as much as three metres (9.8 feet) away with unerring accuracy or diffused over a larger area as a mist. Passing through this stink-bomb cloud generally puts off even the most persistent of predators, which range from the great horned owl to wolves, foxes and badgers.
Skunk and disorderly Stink isn’t their only defence… Skunks are one of a handful of mammals to evolve built-in anti-venom Given their formidable spray, most predators, understandably, give skunks a very wide berth. The main threats they face come from above, from the likes of eagles and owls, which have a fairly weak sense of smell. However, skunks have some additional biological aces up their sleeve that help them to capture prey of their own: namely, a very high tolerance of venom. It’s not uncommon to see skunks scratching at the nests of honeybees to lure out the angry occupants. Unlike most beehive burglars they’re not a er the sweet honey inside, but rather the bees themselves. They can chew through hundreds in a night and barely seem to bat an eyelid at the insects’ stings. Even more impressive, toxic serpents are also on a skunk’s menu. In a battle between a skunk and a rattlesnake, it’s generally the former that will come out on top thanks to a natural resistance to the snake’s own chemical weapon. There’s been little research into how skunks specifically endure bites that could be lethal to much larger animals, but in fellow venom-resisting species – such as mongooses, opossums and hedgehogs – there are two main explanations. Either their bodies naturally produce proteins that neutralise the effects of venom, or their cells have adapted to prevent venom neurotoxins from binding.
“In a battle between a skunk and a rattlesnake, it’s generally the former that will come out on top”
It’s not all black and white Here are three skunk myths that need busting Skunks are purely pests Okay, so they do have their not-so-good points, but it’s important to remember that these animals will only use their spray in self-defence. What o en gets overlooked are the benefits that skunks offer: they eat many unwanted critters, including nuisance insects and rodents, as well as carrion and fallen fruit.
Tomatoes eliminate the odour Juice from tomatoes or citrus fruit may temporarily mask the offending smell that skunks give off, but they don’t get rid of it. You’d be better off using a combination of baking soda, washing liquid and a little hydrogen peroxide to combat the odour with chemistry if you haven’t managed to avoid it.

They spray with impunity There’s a common perception that skunks are ‘trigger happy’ when it comes to firing their whiffy weapon. However, they give plenty of signals, including raising their tails, stamping their feet, growling, making minicharges and even doing ‘handstands’ in the case of spotted skunks.

Stink badger Stink badgers are New World skunks’ closest relatives and part of the wider Mephitidae family. The Sunda stink badger (pictured) is found on several islands in Indonesia and Malaysia.

Skunks are serial squatters Why have one home when you could have ten? While skunks are equipped with the tools to dig their own burrow, including strong front feet and elongated claws, they’d much rather move into an abandoned home or a pre-made shelter. Their favoured haunts include holes dug by foxes and groundhogs, hollow logs and log piles, and in more urban areas, the gaps beneath decking or inside accessible outbuildings. Most skunks will have multiple dens – occasionally as many as ten and sometimes even more. This means
they have several options should they need a safe place to bolt during a night forage. Certain dens are better suited to particular seasons, so they will often have different winter and summer homes. In winter burrows skunks have been known to share their residence with their own kind and even other species, such as raccoons and rabbits. These communally minded animals gain the mutual benefit of social thermoregulation during the colder months.

LEAST CONCERN
The oilbird is one of just two species of bird known to echolocate, emitting rapid clicks to help it fly at night and navigate dark caves. While bats produce calls too high for us to hear, oilbirds click at a frequency audible to humans.
Because they’re either flying or roosting, oilbirds have small feet that can grip onto cave walls but aren’t much use for standing or walking. When the birds are in the air they’re very agile, twisting between obstacles, and they are even able to hover.
They produce unsettling calls
Their chicks get dangerously fat Young oilbirds gain so much weight before fledging that they end up considerably bigger than their parents. Because a lot of their diet consists of regurgitated oil palm fruit, indigenous people used to catch the plump squabs to render oil from their fat.
They never get to see sunshine Oilbirds live their lives in darkness. They’re the world’s only nocturnal, fruit-eating flying bird, travelling many kilometres each night in search of food for themselves and their young. When dawn arrives the birds return to communal roosts in caves and remain there until nightfall.
They build unusual nests in caves In a communal roost there’s no shortage of droppings. Oilbirds make use of their situation by using the accumulated waste to build their nests. Females lay two to four small white eggs, and chicks remain in their dropping nests for about four months after hatching.

The oilbird’s Spanish name is guácharo, which means ‘whining’, and in Trinidad it’s sometimes referred to as ‘diablotin’, French for ‘little devil’ – these are in reference to the bird’s eerie shrieking and screaming calls that carry far through the trees.

Shark myths The Meg
© Getty; Barcroft Media
The shark film set to terrify cinemagoers this year is The Meg. Inspired by Steve Alten’s novel of the same name, it employs the common theme of a man-eating shark but with one big difference: the villain in question is 23 metres (75.5 feet) long! The megalodon is probably the largest shark ever to swim the oceans. While the film exaggerates its size, it could still reach 18 metres (59 feet) in length – three-times bigger than the largest recorded great white shark. Fossil records suggest megalodons roamed Earth’s waters chomping on adult whales with 17.8-centimetre (seven-inch) teeth until around 1.6 million years ago. Most scientists believe the species was completely wiped out, but some people believe it could still be lurking in waters too deep for us to explore.

Shark myths
The world’s biggest fish, the whale shark, lives on a diet of plankton.
1. Sharks will target swimmers, divers and surfers Thanks to the movies, sharks are thought of as ruthless killers targeting any human foolish enough to get in the water. You might find it reassuring to know just a few of over 400 species are considered dangerous, and you’re far more likely to be killed by a cow than a shark. There are around 16 shark attacks each year in America, but just one fatality every two years. The Shark Trust believe the ‘monster’ image is not one sharks deserve. Conservation officer Cat Gordon says, “Sharks need to be treated with respect, like any wild animal. Even a typically ‘harmless’
68
filter feeding shark like a basking shark is capable of breaching clean out of the water, so it’s wise not to get too close. “When humans are bitten, these incidents are inevitably high profile due to their traumatic nature, but they are usually the result of an exploratory bite to see if the target would be suitable prey. The number of reported shark bites is relative to the number of people entering the marine environment each year, with increased popularity of ocean-based recreational pursuits and technology allowing people to remain in the water for longer.”
Shark myths 2. You can hide from sharks among jellyfish In the 2016 thriller The Shallows, the main character finds herself stranded in water with a great white shark determined to eat her. The film follows her efforts to escape from the giant predator, including hiding among a group of jellyfish. If you ever come face to face with a shark, don’t waste your time looking for jellyfish. Sharks have really thick skin covered in tooth-like scales, so stings would be no more than a tickle. The only vulnerable parts are their eyes, but membranes can be lowered to protect them. If you’re heading to British beaches this summer, the Shark Trust stresses that you’re extremely unlikely to get into a situation that requires outsmarting a shark in the first place, as Cat explains. “White sharks stalking British beaches stories have almost become an annual fixture of the summer. There has never been enough evidence to confirm the presence of white sharks in British waters, yet certain sections of the media o en run with sensationaliststyle reporting when dorsal fins are glimpsed or a dolphin strands on a beach. “Facts are ignored and unnecessary public concern is o en created - far from informing the public, this style of journalism has a detrimental impact on sharks and shark conservation.”
“Sharks have really thick skin covered in tooth-like scales, so stings would be no more than a tickle”
A swimmer scratches their hand and a single drop of blood falls into the water. A few bars of ominous music later, a hungry shark appears to claim their free meal. It’s a classic image, but is a shark’s sense of smell really that good? Not quite, according to the Shark Trust. “Sharks have a highly complex and acute sense of smell. Their highly evolved olfactory organs allow them to detect the blood of potential prey, pheromones from a potential mate or the scent of a predator from a great distance - one part of blood to one million parts of water. That’s equal to one teaspoon in an average-sized swimming pool,” adds Cat. For blood to reach the shark’s olfactory system it first has to dissolve and travel through the water, which would take more than seconds. As we’re not their normal prey, sharks following the scent of blood aren’t targeting humans – they’re either investigating or, in the case of ocean whitetips and silky sharks, following their instinct to look for thrashing wounded animals.

3. Sharks can smell a drop of human blood
69
4. Some sharks go rogue and get a taste for human flesh Many films, from Jaws to The Reef, feature a single ‘rogue’ shark as their villain. The book Jaws was written at a time when some people believed sharks could develop a taste for humans and choose to hunt them instead of their natural prey. This theory has largely been dismissed but, as Cat explains, the rogue shark concept gripped film fans and refused to let go. “Shark films have morphed into a new film genre, with sharks filling the sort of ‘villain’ slots occupied by aliens and zombies.”
5. Sharks leap from the water to attack boats The glimpse of a fin sliding through the waves, then the huge creature launching itself at people on a beach or a boat – it’s a common theme in movies with sharks as antagonists. Of the hundreds of species, just a few come close enough to the surface to expose their fin, and most people claiming to have seen a great white off the coast of the UK were actually looking at a basking shark, dolphin or porpoise. As for the idea of a shark leaping from the ocean a er a human, it’s not something that’s ever been seen in the real world. The great white shark can jump 2.4 metres (eight feet) out of the water to grab seals and birds, but a boat doesn’t look like prey. It will sometimes wait in the shallows for seals as they head out to sea, but launching onto land is the speciality of the orca. One shark that does (accidentally) land on boats is the shortfin mako. As well as being the fastest species, this shark is capable of leaping nine metres (30 feet) above the surface, and these record-breaking jumps sometimes put them on a collision course with passing vessels.
Peter Benchley, the author of the novel Jaws, felt terrible about the repercussions of his story and has been promoting shark conservation for decades.
70
For a carnivorous shark to switch to a diet of humans would make very little sense at all. Not only are we far less common in the oceans than fish, seals and seabirds, but we also provide much less energy than an insulated animal like a sea lion. Given the low percentage of people who are actually killed in attacks, some scientists even argue that we taste bad to sharks; most bites to humans are exploratory, and the sharks move on when they realise they’ve mistaken a swimmer for a seal.
Shark myths
Small sharks The big sharks might get all the attention, but about half of the species are under a metre long
Dwarf lanternshark The world’s smallest shark is just 21 centimetres (8.3 inches) long when fully grown. They live off the coast of Venezuela and Colombia and use bioluminescence to catch their prey.
Smalleye pygmy shark Just a centimetre bigger than the shark above, the smalleye pygmy shark is another tiny species. It spends its days in deep water, migrating towards the surface when the Sun goes down.
Pocket shark Pocket sharks have large pocket glands behind their pectoral fins. Their purpose isn’t understood, but they might release pheromones or a luminous fluid into the water.
Spine pygmy shark To avoid being eaten, spined pygmy sharks have bioluminescent organs on their undersides, making it hard for predators below to see them against the light from the water’s surface.

Shark myths
6. Sharks live for thousands of years Investigating the deaths of the great white’s victims in Jaws, police chief Martin Brody reads that sharks can live for 2,000 to 3,000 years. He should probably have checked a different book, because no shark species has a lifespan even close to that. Although it’s been found to live longer than previously thought, the great white shark’s average life is still a modest 70 years long. It may not meet movie expectations, but one shark does claim the record for longest-living
vertebrate on the planet. Greenland sharks, residents of the cold waters around the Arctic Circle, have been found with up to 400 years already behind them. It’s thought that their large size combined with the low temperatures they live in result in a slow metabolism and a drastically reduced ageing rate. These sharks are still something of a mystery; their long lives were only discovered a few years ago, and little is known about what they do with their centuries in the sea.
7. Sharks have tongues As a great white shark launches at its potential victim in Jaws 3-D, a huge pink tongue flaps in its gaping mouth. But while sharks do have something similar to a tongue, it doesn’t look anything like ours. The shark equivalent of a tongue is called the basihyal, and it’s something they share with the other bony fish. While four-limbed vertebrates have long, flexible tongues used for tasks like manoeuvring food,
the basihyal is the front section of a bar of cartilage running from the chest to the mouth. Its primary function is to support the bones associated with the gills, so it’s pretty rigid. In a few species, including bullhead and carpet sharks, the basihyal is bigger and more flexible, and it can be teamed with strong throat muscles to help suck prey into the mouth. The cookiecutter shark, a small dogfish shark, makes the best use of its ‘tongue’, earning its name by taking cookie-shaped chunks of flesh out of its prey with its sharp teeth and then vacuuming them up.
“The shark equivalent... the basihyal’s primary function is to support the bones associated with the gills” 72

8. Sharks can swim backwards

Jaws 3-D, the third instalment in the Jaws franchise, centres on a pair of great whites that sneak into SeaWorld. In one sequence, the larger shark backs out of a filtration pipe at enough speed to break through the grille trapping it there. That really should have been the end of the story for the man-eating shark, because sharks can’t swim in reverse. They’re propelled by their tails and use their pectoral fins for balance and turning, and their anatomy simply doesn’t allow them to go in any direction other than ahead. While many sharks are able to pump oxygen-rich water through their bodies using their pharynxes as they lie on the seabed, some species – including the great white – lack this ability and have to swim forward constantly to keep water flowing over their gills.

Shark myths
9. Sharks seek revenge The great white shark in Jaws: The Revenge is so determined to wreak havoc on the Brody family that it follows them from the northeast coast of America to the Bahamas. As perfect as it would be for filmmakers, sharks aren’t really capable of holding grudges – their main motivation is always just getting enough to eat. Sharks are intelligent fish, and it’s been shown that they’re capable of learning. When tour boats repeatedly feed them they begin to associate people with food, but vengeance doesn’t enter their minds. If sharks were capable of revenge, it would arguably be justified; we’re much more dangerous to them than they are to us. While they kill less than one person a year, in the same amount of time 100 million sharks are killed by humans. Many of these are victims of the shark fin trade, their fins cut off for soup and traditional medicine and their bodies thrown back into the sea, but others are killed in the hope that it will make the oceans safer. Not long after the release of Jaws shark hunting became popular, and in 2014 the Australian Government began a controversial (and short-lived) cull of sharks around the west coast.

evolved bodies for stealth. Not only do they produce no vocalisations, their scales are the ideal shape for sliding silently through the water. The only exceptions come in the form of the draughtsboard shark and the swell shark. These species quickly force water into their stomachs if they’re threatened,
puffing up to several times their normal size in an attempt to deter their assailant. If they’re successful, the sharks relax and the water rushes back out. If fishermen accidentally catch either of these sharks, they gulp air instead of water – they can’t hold on to the air for long, so it gets expelled with a loud bark.
“Sharks play a vital role in marine ecosystems and are valuable for both tourism and wellbeing, as they provide enjoyment for many.”
After decades of being feared, persecuted and overfished, it’s about time we began to respect and appreciate the magnificence of sharks.

Seen the world over as emblematic of the land down under, Australia’s love of kangaroos is far from universal, with many regarding them as nothing but pests. A controversial new film has stoked the fires of a national debate Words Charlie Ginger Australia. Land of beaches, Neighbours, Vegemite and, of course, kangaroos. In fact, nothing quite says Australia like the sight of these loping marsupials bounding across the outback. Any country would be proud to call these imperious jumpers their own. Well, not quite. While many Australians do indeed cherish their national animal (of which there are reported to be between 47 and 50 million), a film that is currently premiering across the globe has lifted the lid on one of the country’s darkest secrets: kangaroo culling. Simply titled Kangaroo, it has proved to be the spark that has ignited a national debate now raging from Geraldton to the Gold Coast. We spoke to the film’s directors, Kate McIntyre Clere and Michael

McIntyre, prior to attending the London premiere in early June, and we started by asking them why they decided to focus on the plight of kangaroos in the first place. “Kangaroos are one of the most recognisable symbols in the world and have always held a fascination for us. No film had explored this icon before. We set out to make a story that celebrated this magnificent animal but soon discovered that the kangaroo was at the heart of a bitter, complex and divided situation in Australia. We were shocked to learn that millions of kangaroos are shot each year as so-called pests and sold for profit. “To find out where it started and why it still happens today, we needed to investigate the origins of an industry

and government partnership that has become the largest wildlife slaughter in the world. Where had the ideology come from that a native animal that has lived in Australia for millions of years could be a national problem? How and when did Australians start believing kangaroos were a pest and therefore must be eliminated?” Incredibly, this wide-scale culling has, until now, remained largely in the shadows, with the general public seemingly unaware of what has been happening, a view reinforced by the McIntyres. “When we started work on the film, an early interview with a government scientist revealed that the killing of kangaroos in Australia was the largest terrestrial wildlife slaughter in the world. As Australians we found this alarming and had never heard this mentioned before across any media. As storytellers we wanted to find out what was going on.” Yet this would prove no mean feat. “One of the biggest issues we faced in making this film was examining the population figures that the Australian Government publishes every year about how many kangaroos there are,” explained McIntyre. “So we unpacked the survey methodology that the government uses to get those numbers. To our surprise we discovered how flawed the methodology is, and so we got expert testimony on how inflated the Government estimates are. “On the subject of how many are killed, we discovered that with the growth of the commercial kangaroo industry, so-called pest mitigation, recreational and illegal shooting, as well as road-kill and other accidental/collateral death, there is no data collected on the number of kangaroo deaths that occur daily and how many kangaroos remain. Some scientists and conservationists are reporting both local and regional extinctions.” While the film has certainly uncovered many talking points that are now rightly being discussed across

Australia and in parts of the wider world, it has also come in for some stiff criticism from those in the kangaroo meat industry who feel it is too one-sided in its approach. And although the directors spoke to a wide range of people while shooting the film, it would be fair to say that it does not lend much screen time to the other side of the argument, which seems like an oversight given the lengths the directors went to in order to gather a host of opinions. “We knew we would have to immerse ourselves in all aspects of the story, and we worked to get interviews from the many differing stakeholders,” said McIntyre. “We interviewed indigenous Australians, scientists, commercial shooters, farmers, politicians, artists, wildlife carers, chefs and activists so we could unpack this cultural paradigm. “Most people were keen to get their side of the story heard. As the issue is so polarised in Australia there has been lots of shouting and resistance on social media and across the press since the film’s release. The film certainly struck a nerve.” Many of the nerves on which this film is getting belong to the people who rely on the kangaroo meat
trade for a living, some of whom have labelled the film a ‘beat up’ on the industry and point to the monetary reasons behind keeping wild populations in check. Kangaroo farming is estimated to generate $200 million (approximately £150.7 million) annually for the Australian economy and creates over 4,000 jobs, including 2,000 kangaroo harvesters. In 2010, kangaroo meat was exported to 55 countries around the world, a number that has since risen to over 60. These figures help (in the eyes of many) to form a robust economic argument for the continuation of culling, and this is before the environmental benefits of doing so are considered. Research conducted in 2014 suggests that reducing the number of roos may well help other members of the outback. Published in the scientific journal PLOS One, the findings revealed that in areas of low kangaroo grazing reptiles were three times more abundant: in territories that are heavily cropped by these marsupials no reptile of any kind was prevalent. Then there is the damage to agriculture that kangaroos cause. While some may argue that they were there first, the fact that roos will often trample over crops and rival livestock for water and grazing cannot be ignored when Australian farmers export

77 per cent of what they produce, a fact that generated $60 billion (£45.3 billion) for the Australian economy in 2016–17. While the idea of shooting these beautiful animals understandably upsets many people, it is worth noting that in order to kill a roo one must be in possession of a permit – downing a kangaroo without one can result in a A$10,000 (around £5,500) fine. It is also important to consider exactly how many kangaroos are culled annually. According to Federal Agriculture Minister David Littleproud just three per cent of the kangaroo population is harvested, which, if true (the directors do not agree with this figure), does seem to punch a serious hole in the film’s claim that kangaroos are in danger of disappearing. Even so, this may not have been the main point that the McIntyres were driving at when filming, as is perhaps revealed in their answer when we asked what they hoped their film would achieve. “With breathtaking footage of kangaroos in the wild, we hope this film will give the audience an up-close experience of this unique species and bring to the table a conversation that Australians seem reluctant to have. It’s time people in Australia and across the world know what is going on and ask the question: why is no one responding to the barbaric treatment of this magnificent wildlife?”

The Cove This controversial documentary won an Oscar in 2010 for its hard-hitting expose of dolphin hunting in the town of Taiji in southern Japan. Although generally received positively, the film was accused of portraying the Japanese as a brutal people. Either way, this film makes for a difficult watch and brings to the surface an industry that has o en remained in the depths.
Earthlings Known as the ‘vegan maker’, this utterly harrowing film was released in 2005. Presented in five chapters (pets, food, clothing, entertainment and scientific research) and narrated by three-time Oscar nominee Joaquin Phoenix, this documentary pulls no punches in exposing humanity’s hideous treatment of animals.

The experience of seeing these huge, intelligent and untamed creatures in their natural habitat is breathtaking, and you’ll learn far more in just a few minutes with a wild herd than you would from days with a captive elephant as you observe their [natural] behaviour. Seeing one of the world’s largest land mammals move across the African savannah or shuffle through an Asian forest is
unforgettable; the way an entire herd protects a tiny baby, the care with which desert elephants treat the scant vegetation, or the heart-stopping mock charges if your vehicle separates a herd crossing the road. Another option is to volunteer, for instance, working with elephants rescued from logging or riding and given sanctuary in large enclosures rather than those that offer rides or performances.

elephant l ffacts you’ll never forget
Blaring noise An elephant’s trumpet sound can travel over ten kilometres (6.2 miles). It denotes aggression, distress or excitement to other animals in the not so local vicinity.
Witness unbreakable bush elephant bonds Elephants experience perhaps the strongest relationships on Earth, and herds stay together for their entire lives. African bush elephant families comprise of up to 50 females of several generations, and the closely bonded animals graze, travel and search for water together. Males are expelled from the group once they reach sexual maturity to avoid inbreeding. Adult males were once thought to be solitary, but in fact they form their own herds of bachelors when not in season. Males ready to mate will impregnate females before resuming their lives without the ladies.
Incredible incubation Elephant pregnancies last 22 months, just eight weeks shy of two years! This means elephants calves are advanced and can walk within ten minutes of birth.
Long friend lists Like humans, elephants can recognise other individuals from their voices alone. Each animal can distinguish over 100 different friends by the sounds they make.
Staying sober Elephants don’t eat fermented fruit to get drunk as they don’t search for food in the same areas in which rotting marula fruit lies on the ground. Even if they did it would take almost 1,500 pieces of the fruit to get an elephant drunk.
Delicate touch An elephant’s trunk is so dextrous it is able to pick up a single grain of rice. The trunk’s tip is around as sensitive as human lips.
84 84
Ride denied Elephants are enormous, but they aren’t the loadbearers one might think. Elephant spines are comprised of sharp, angular bones that protrude upwards and the tissue between the vertebra and the outer layer of skin is extremely vulnerable to excess weight. Pressure from above can cause the animal extreme discomfort, and over time this can result in permanent spinal injury. If seeing wild elephants really isn’t enough for you, there are walking and washing interactions at rehabilitation centres that don’t involve riding or deviating from natural elephant behaviour at all.
Related elephants babysit for their siblings, and all the herd’s adults pitch in to help raise the calves. The oldest and largest female takes charge, and her hard work strengthens the family unit. She defends the younger members of the group from predators and makes decisions about where to search for food and water. When looking for elephants on safari, it is worth noting that they are often heard before they come into view. Adults crash through dense vegetation to allow the youngsters to follow and they produce lowfrequency rumbles in order to communicate over distance.

Revere a real-life Indian deity The elephant Hindu god Ganesha represents intellect and wisdom and is said to remove obstacles. Indian elephants embody these values and have become an intrinsic aspect of Indian life. Elephants have been domesticated over centuries and live alongside humans. This has been known to cause conflict between farmers and hungry heffalumps, but planting particularly fragrant crops or locating beehives around fields is enough to get elephants to look elsewhere. Elephants are used in celebrations and festivals in India, but those wishing to see elephants in their natural surroundings are in luck. Around 60 per cent of Asia’s wild elephants are in India, and they are most densely populated in the southern tip of the country. However, their population has reduced by 50 per cent over the last three generations due to human land use. If you can stand the heat, see these massive mammals in their native habitat before their home ranges shrink any more.
Watch Sri Lankan elephants taking a dip Whether it’s the salty sea or an inland reservoir, water is extremely important to elephants. There have been cases where elephants taking a dip in the ocean have had to be rescued 16 kilometres (9.9 miles) from shore after getting caught in a current – thankfully these animals are able to breathe through their long trunks just like a builtin snorkel. When they aren’t riding the waves, Sri Lankan elephants can often be seen squelching around in muddy ponds and coating their skin with Sun-repelling clay to cool down. This allows the animals to spend maximum time foraging in grassland under the hot Sun. It’s important to avoid supporting elephant captivity masquerading as rehabilitation. Tourism is an extremely lucrative industry in Sri Lanka and a great number of visitors are satisfied with paying for an elephant selfie. Animal welfare advocates stress the importance of watching elephants in the wild rather than so-called ‘orphanages’ that exist purely to make money.

Glimpse Sumatran elephants gardening Indonesia’s island of Sumatra is home to a huge array of endangered species, including tigers, orangutans and the Sumatran elephant. As a huge herbivore, these giants are responsible for depositing seeds around this fragile ecosystem. Not only do plants get to spread their roots as a result, but dropped seeds are mixed into a readymade fertiliser in the form of elephant droppings. Elephant dung also supports countless species of insects, providing a food source and a safe place for creepy crawlies to lay their eggs. Every animal in the food chain is extremely important,
and allowing just one species to disappear could have huge repercussions for those that remain. Sumatra has seen a human population surge in recent years, accompanied by a high demand for palm oil. This ‘miracle’ ingredient makes its way into thousands of products on Western supermarket shelves, but procuring it requires clearing native trees to make way for animalunfriendly oil palm trees. Along with supporting ethical tourism to see wild elephants in Sumatra, you can help out at home by avoiding products with palm oil or ensuring they are sustainable.
The origin of this subspecies is the subject of some debate, but it is generally accepted that captive elephants were introduced to Borneo by the Sultan of Sulu in the 18th century. As a result of descending from domesticated animals, they are much tamer than other wild elephants, yet they still like to venture far and wide. While they would usually range across a territory spanning up to 400 square kilometres (154.4 square miles), in fragmented areas of jungle they can be forced to wander across 600 square kilometres (231.7 square miles) of terrain to find food. Visitors to Borneo should travel with experienced guides. The island has overwhelming biodiversity that not everybody will be fortunate enough to encounter, but it’s no walk in the park. Trekking the Bornean jungle is an exhausting and dangerous pursuit that should not be taken lightly. It’s also very important to keep your distance from the friendly animals in order to prevent the elephants from losing their fear of humans entirely.

Explore the Earth
Spy forest elephants through the trees The straight, white tusks of this magnificent species help uproot trees and strip bark from trunks. These are both important food sources for this elusive elephant, along with leaves and various fruit. All of this roughage wears down their tough teeth, so these elephants grow six replacement sets throughout their lives. Though concealed within thick woodland, predation is still a problem for elephants. Lions and hyenas will target a young calf that has strayed away from the family, and they will even attack a sickly adult. However, aside from these threats, forest elephants coexist with other species peacefully and provide important services for other woodland creatures. Elephants dig for water when it is scarce, benefitting a great number of other animals, and their propensity to charge through vegetation creates corridors for the rest of the forest’s inhabitants, disperses seeds and fertilises the environment with their immense piles of dung. Even elephant footprints are useful to Africa’s ecosystem, with divots driven into swampy soil being able to hold up to 200 litres of water. Up to 61 different species have been recorded occupying these little lakes, which elephants provide simply by existing. This species occupies four west African countries and can be spotted by the lucky few adventurous enough to explore the forests. This should only be attempted with reputable guides, as armed rangers patrol the woods to protect the animals from illegal poaching.

Warning signs Chains Elephants should never be shackled. If an elephant poses a danger to another animal or a human when it is not chained it should not be in captivity. Don’t hand over money to a facility that chains up its animals.
Rides It’s best to avoid tour operators that offer rides, even if you choose not to take a turn. Make a statement with where you put your cash, and don’t reward anyone taking advantage of endangered elephants.
Touching Wild elephants should be just that – wild. Elephants are perfectly capable of injuring or even killing a human if one strays too close. Touching wild elephants also sends the message that all humans are harmless, which is definitely not the case.
Feeding Elephants spend up to 16 hours a day finding food, and being the middleman robs the animal of its daily drive. Nature provides everything an elephant needs, and while it may be an enjoyable experience for you, the animal won’t thank you for feeding it.
Concrete The wilderness is a place free from human-made objects, and there is no room for hard cement in an elephant’s life. Stamping those giant feet is a form of elephant communication that the animals rely on to stay in contact.
Travelling to a country to see elephants sends a strong message to the nation’s policy makers. Your money is an economic incentive to protect elephants from poaching and provide a sustainable future for endangered animals. It is our responsibility to prove that species like elephants are much more valuable alive than dead. The ivory trade is still a threat. When a resource is scarce it becomes more coveted. Laws will tighten and eventually private collections of ivory will make their way into the hands of authorities. It’s simply a matter of time. Hopefully elephants will survive long enough to bounce back.

Bears and bustards:
EUROPE’S BEST WILDLIFE EXPERIENCES Not flush enough to go on safari? Haven’t got time to explore the Amazon? No problem says the author of a new guidebook; Europe’s packed with spectacular animals Words James Lowen Gargantuan walruses lounging on Arctic icebergs. Barbary apes peering towards Africa from atop the Rock of Gibraltar. Rare Azores bullfinches singing on forested volcanoes in the mid-Atlantic Ocean. Brown bears lolloping through Italian mountains. How rich, how varied, how thrilling is Europe's wildlife? And in such spectacular landscapes too! Ah, yes, brown bears. This was the creature that arguably inspired my nature-oriented journey throughout Europe – from Italy to Iceland, from Trujillo to Tallinn. Having written guides about the glamorous wildlife of Antarctica and South America, I returned to the UK and immersed myself in penning books starring British animals and plants, but wanderlust eventually bettered me, beseeching that I again expand my horizons. With a young child, months photographing Africa's ‘Big Five’ or escorting people around polar regions were impractical options. Short breaks within a few hours flight, however, were eminently feasible. So what amazing creatures might it be possible for me – or you – to see on a wildlifewatching weekend somewhere in Europe? And so, properly this time, to those brown bears. Why travel to Alaska to see grizzlies when Europe offers so many different ways to experience half a ton of ursine heft? It was during a May dusk in Romania’s Transylvania, the gloaming bristling with anticipation, that I finally clasped eyes on a brown bear. Failing light made for frustrating photography, but such modest disappointment was more than outweighed by the ease of travel. In three days – barely a long weekend – we watched bears and
90
enjoyed the wondrous water world of the Danube Delta. This got me thinking… where else could you see brown bears in a weekend? In several places, it transpired. A night in a comfy hide in the Finnish taiga would provide near guaranteed views, with the added bonus of grey wolves. During a spring evening in a spartan Estonian construction, raccoon dogs provided complimentary excitement. But why not shun hide-based observation altogether in favour of sitting in the open? In Spain's Somiedo or Italy's Abruzzo you can easily scan favoured hillsides for bears exploiting autumn’s berry bonanza. And it's not just Ursus arctos that you can see in an easy weekend. Thanks to the advent of low-cost flights and ever-improving information about where to see special creatures, you can enjoy ‘once-in-a-lifetime’ wildlife experiences all over Europe – every weekend of the year. This is the precise conceit of my new book, 52 European Wildlife Weekends. It proposes a year’s worth of superb, animal-and-plant-packed short breaks, each carefully timed and packaged to maximise efficiency for the timepoor traveller. So shun the New Year blues and head to Poland to watch herds of European bison browsing in the snow. Escape the winter by gawping at houbara bustards prancing around a desert in the Canaries. Alternatively, embrace the snow by venturing north of the Arctic Circle to be mesmerised by Varanger's ‘king eider vortex’.

to Corsica for endemic birds and flowers. If you’re feeling romantic, why not escape on a city break to an Italian hilltop town that throngs with lesser kestrels. And so on across the year until you spend Christmas in the Camargue watching shockingly pink greater flamingos and being astonished by wallcreepers, a cliff-hugging creature that appears to be half-bird, half-butterfly. So what of the other cover stars from the book? Can you really see such exotic creatures (Arctic foxes, twotailed pashas, little bustards and sperm whales) in just a weekend? The answer is short and unequivocal: yes. For Arctic foxes, head to Longyearbyen on Spitsbergen. Even in the outskirts of this frontier town this carameland-chocolate-coated canid sniffs the ground for barnacle goose eggs. While you are in the Norwegian Arctic you can take a trip to marvel at walruses and bearded seals. With a multitude of vibrant colours adorning massive wings, two-tailed pashas looks like a butterfly that would be more at home in tropical rainforests than in Europe, and that wouldn't be too far from the truth. This winged wonder is a largely African species that scrapes into Mediterranean Europe. To find it, try Extremadura in central Spain in late May: Monfragüe Castle – which also has vultures floating overhead and white-rumped swifts careering past – is as good as anywhere. On your Extremadura weekend it would be rude not to pop to the grassy plains of Cáceres and enjoy another cover star. Male little bustards attract females by making a call that sounds like someone blowing a raspberry. Shortly after dawn, they accompany this delightful sound with an eye-catching display of dance – their own salute to the Sun – flashing white wings above crimson poppies.
People often think they have to travel thousands of miles to go whale watching – to New Zealand's Kaikoura, for example. Few realise you can have a thrilling oceanic excursion closer to home. Take a boat trip off southern Ireland in late autumn for fin whales, or snorkel with orcas in Norway, with the aurora borealis as a support act. All of which brings me to our final cover star, the sperm whale. Perhaps no animal illustrates more clearly why we would be daft to shun Europe in favour of far-flung destinations. Sperm whales are Kaikoura's main draw, yet you can easily gasp at this giant much closer to home on a weekend in the Azores or Madeira, or in Norway's Versterålen, or even by taking a ferry ‘mini-cruise’ from Portsmouth to northern Spain. It’s never been easier to witness Europe’s wildlife. So, what are you doing next weekend?

Jays Although not all closely related, there are around 50 species classed as jays, and they have loud voices, bright colours and impressive intelligence in common
Florida scrub jay The local celebrity As its name might suggest, this jay is native to Florida – in fact, it’s lived there for at least 2 million years and is the only bird endemic to the state. Because it can’t be found anywhere else, keen birdwatchers travel long distances for a glimpse of the jay among Florida’s sand pine scrub. These birds live in flocks, and helpers assist breeding pairs with their offspring. Like other corvids,
these jays are intelligent and inquisitive and have sometimes been seen approaching and flying off with shiny objects. Living in such a small area has its downsides though. The Florida scrub is under threat as development continues in the state and large trees have been allowed to take over some areas, and the jay is now the focus of several conservation projects.

The sh shady species This distinc distinctive bird occupies the forests along America’s northwest c coast, where its dark blue plumage helps it to blend into tthe shadows. Outside of the breeding season Steller’s jay jays live and forage in flocks, and they can be spotted travelling ac across clearings and glades in neat single file. Using the their strong beaks, these jays smash open hard seeds and nuts an and crunch invertebrates like beetles and wasps. In spring and an summer they’ll also tuck into berries, eggs and fruit, with males m feeding their partners while they incubate clutches of eggs in nests made from twigs, grass, pine needles and a even paper. Steller’s jays have a wide repertoire of sounds, soun n including imitations of other birds, and they become beco om especially loud if any animal gets too close to their the ei brood.

LEAST CONCERN
Blue jay The bold blue bird As they dart through the forests of Canada and the US hiding acorns ready for winter, blue jays produce flashes of colour between the trees. The bright blue doesn’t come from a pigment; it’s caused by the complex inner structure of the feathers scattering the light reflecting off them. The small crest on the blue jay’s head lies flat when the bird is feeding and resting but becomes raised when it’s excited or agitated. This jay is known for being loud and bold, fighting viciously with rivals and screaming when it spots a predator. It’s worth trying to ward off an attacker, because blue jays aren’t very fast flyers and are easy to catch for swift birds like hawks.
Because the colour of the blue jay’s feathers comes from the structure and air spaces within them, a crushed feather would appear black.

Inca jay The parents with their nests full INCA JAY Cyanocorax yncas Class Aves
There are several subspecies of Inca jay, each with different length bristles over their beaks.

LEAST CONCERN
Siberian jays are awkward fliers in the open, but in their preferred habitat of dense forest they can hide and dodge between trees to avoid predators.
Territory Andes Mountains, South America Diet Seeds, fruit, insects, small vertebrates Lifespan 10–11 years Adult weight 66–110g (2.3–3.9oz) Conservation Status
LEAST CONCERN
Once thought to be a subspecies of the green jay, the Inca jay is now often classed as a separate bird. This tufted species lives in the Andes in South America. Breeding pairs build nests in dense bushes and work together to care for their chicks. Offspring often remain with their parents for several years, helping to raise their siblings. Unfortunately, all of this effort can be exploited by giant cowbirds; these brood parasites have been seen laying their own eggs in Inca jay nests so that the hardworking teams will raise the planted chicks alongside their own.
Siberian jay The jay dressed for winter Smaller than other corvids and more similar in shape to songbirds, you’d be forgiven for not identifying this species as a jay. The Siberian jay lives throughout coniferous forests in Scandinavia, Russia and some northern parts of Asia, where fluffy plumage helps it to cope with the extreme winter temperatures. Siberian jays live in small groups with a single breeding pair, some of their offspring and some unrelated birds. They’re monogamous and will stay in the same territory with their partner for life. They mostly eat seeds, berries and small invertebrates.
Eurasian jay
1. Smallest Dwarf jay At just 40g (1.4oz), the dwarf jay is the smallest of all the corvids. It’s endemic to the montane forests of Mexico, where its population is threatened.
2. Fanciest Black-throated magpie-jay Over half of its length comes from its ornate tail feathers. In case that didn’t make it striking enough, it also has a curving black head crest.
3. Most endangered White-throated jay
4. The original Eurasian jay
According to the IUCN this species, which is threatened by habitat loss, potentially has the smallest remaining population.
This was the first species to be named ‘jay’. First described in the 18th century, its Latin name references its loud call and love of acorns.
Not a jay... Black magpie The black magpie, native to Southeast Asia, was long classified with the jays. Closer analysis later revealed that it didn’t belong in this group and, confusingly, nor was it a magpie. It finally found its home with the treepies, a group of long-tailed Asian corvids that spend almost all of their time in the trees.
The oak tree’s assistant EURASIAN JAY Garrulus glandarius Class Aves
Territory Western Europe, northern Africa, Asia Diet Seeds, fruit, invertebrates, eggs, young birds, bats and rodents Lifespan 5 years Adult weight 140–190g (4.9–6.7oz) Conservation Status

Across this vast area of highly varied conditions there are multiple subspeciess that have evolved to look quite different from m one another. In the UK there’s no confusion; n; the Eurasian jay is the only jay to inhabit the country, so this species is simply known as the jay. y. Eurasian jays hoard up to 1,000 acorns a year and inevitably forget get about some; before people started planting g them the birds were the most important distributors utors of the English oak. However, it’s not only y the oak that the Eurasian jay has a special ial relationship with.

The 33 subspecies of Eurasian jay vary hugely in colour, pattern and crest, but they all share the characteristic black ‘moustache’ markings and blue wing patches.

The coyote’s Latin name of Canis latrans translates as ‘barking dog’, a nod to its repertoire of vocalisations

questions@animalanswers.co.uk Do coyotes chase roadrunners in real life? Both coyotes and roadrunners share their habitat, being prevalent in northern America, the Canadian deserts, Mexico and northern California. Despite this, the concept of coyotes chasing roadrunners (derived from Looney Tunes) is a highly unlikely predator-prey situation. There is minimal documentation of such an event in the wild; instead, coyotes show a preference for other prey, such as bison, rabbits, deer, lizards, insects and fish. Roadrunners are also surprisingly opportunistic predators, known to hunt small mammals, reptiles, insects and even rattlesnakes. Even so, considering that a coyote can reach speeds of to 64.4 kilometres (40 miles) per hour, while a roadrunner can only achieve a speed of 32 kilometres (19.9 miles) per hour, if a chase did occur the coyote would catch its target easily. Such speed can be attributed to their differing sizes, with an adult coyote reaching up to 22.7 kilograms (50 pounds) and a roadrunner only reaching 230–430 grams (8.1–15.2 ounces).
Why do some animals have webbed feet?
LEFT Dog breeds including the Newfoundland (pictured) and dachshund all have webbed feet
An array of species have webbed feet – toes connected through a piece of skin. This interlinking structure has primarily evolved for aquatic locomotion, allowing an animal to swim efficiently to capture prey or flee predators. The webbing structure increases the surface area of the foot, therefore pushing against a greater amount of water, aiding speed and navigation. Such a structure is equally as important above water, as webbing eases walking on unstable surfaces, preventing sinking or loss of balance. Most aquatic animals have webbed feet, including ducks, frogs, penguins and puffins.
Follow us at... 96
Puffins reach depths of up to 61 metres (200 feet) when hunting fish, using their webbed feet as a rudder to navigate, whereas swans simply use their webbed appendages to swim while feeding at the surface. Some mammals have also evolved with this structure, including beavers, capybaras and even canine species. For example, Newfoundlands were bred to work in the cold waters of Canada, relying on their webbed feet, muscular build and thick, water-resistant fur.

Animal answers Why do squirrels chase each other? will give chase to determine the reproductive state of a female, which is indicated through her scent. This behaviour can be witnessed throughout the year, as mating can occur between December and February and between June and August depending on the species of squirrel. A final explanatory factor is simply that scuttling a er each other is fun; juveniles will chase as a form of play-fighting, as is also seen in puppies and kittens.

Squirrels chasing each other can be attributed to three factors: dominance, reproduction or fun. Most commonly, the behaviour is associated with establishing territories, as squirrels will chase others to assert their dominance. Territorial species include American red squirrels. However, this territorial trait is not displayed by some species, an example being the grey squirrel. Another reason for chasing is reproduction. Studies have indicated that male squirrels
A er eating the egg whole this snake will regurgitate the eggshell
What kind of animals eat eggs? Ovivores are animals that consume eggs as part of their natural diet due to their high nutritional value. Examples of these animals include snakes, birds, squirrels, deer, cougars, lynx, baboons and skunks. This dietary choice is fundamental to survival, which is reflected in species expending ample energy to locate eggs.
Baboons scavenge by the ocean while the tide is low to hunt for shark eggs; snakes swallow reptile eggs whole; and gull-like birds known as skuas steal penguin eggs. While many animals will strive to protect their eggs from such predators, cuckoos will lay their eggs in another bird’s nest, discarding the nurturing responsibility.
