and expertise you will need, and speaking from my own experience, your love of getting out into the country and down on your knees to examine a wayward bug is lessening as time passes. For the rest of you, though, field biology may well be a new and fascinating pursuit, but you may be bewildered by the array of expensive stuff you seem to need to enhance the experience. Here is my strongly biased list of what is hot and what is not. When you are starting off, you need easyaccess information. Wait until your interest and preferences develop – as they will; you cannot encompass all aspects of biology in depth. Then you can buy specialist books to tell you more. For now you just want to identify things and get a little knowledge about them. I am assuming that you cannot easily read technical French, so the books are in English. Where to my knowledge a French version or equivalent exists, I will say so. Mike George is our regular contributor on wildlife and the countryside in France. He is a geologist and naturalist, living in the Jurassic area of

Guide Delachaux series has a selection. These are the books I find myself using regularly. You may also need one on trees. Of course, if you are computer savvy, you can get a load of information from the Internet. I have myself often used a website which harnesses a variant of image analysis and comparison software to identify wild flowers from photographs. It should be said that books in English tend to use exquisite paintings of insects plants etc., while French books use photographs. There are for and against on this. The paintings are easier to use, but show the specimen in a state you are never likely to see in the wild. Butterflies are beautifully displayed, top and underside views, without a nick or a patch of missing scales. This must be born in mind when comparing your specimen.
EQUIPMENT The next expensive thing is equipment. What do you really need and what can you do without? First and foremost you will need a notebook. In this you will note down what you see, and if you need to identify it, all the diagnostic details you need. You will learn that you cannot overlook any detail. Remember to note where you saw it, too, and the surroundings and conditions.

Another indispensable item is a magnifying glass. I don’t expect you to crawl through the grass-stems with a huge Sherlock Holmes model. What you need is what the experts call a loupe. This is a small glass which folds into a protective cover, is a few centimetres long at most and slips into a pocket or hangs on a lanyard round your neck. The most convenient power is 10x. The only problem is that you will need to master the technique of holding the loupe up close to your eye to get a sufficient field of view. If you buy from an optician, get the seller to demonstrate how to use it properly. Many budding naturalists yearn for a microscope. I certainly did! However, when you get one, you will find that it is in fact not really suitable for the average nature-spotter. The standard monocular microscope uses transmitted light, that is, the light is directed through the specimen and up a tube to the eye. To use this properly, you need to mount the specimen permanently on a slide. The only time you can really use it without careful preparation is to look at a drop of pondwater or a drop of blood. The interest rapidly palls. If you want to study rocks or we are blessed with palm-size digital crystals, an ordinary microscope is not cameras with features we oldies could only suitable, and specimen preparation is very dream of. And you can instantly check if costly and time-consuming. Believe me, you got a good picture and re-take it if you I’ve done it! didn’t. Do get one that has a wide-ranging Far better is a binocular dissectingtype microscope. Now this doesn’t mean I am expecting you to dissect creatures – that’s the last thing I’d suggest. The advantage is that you view zoom, good close-focus and manual focussing if possible. This will save the fag of writing a full description of anything you don’t recognise. Besides, you always overlook one vital diagnostic feature. the specimens in reflected light, using I must say my cynical views on both eyes so you get depth and shape smartphones as cameras have recently information, and you don’t have to kill the been modified.

small size. A wide objective collects light – a binocular with a 50 diameter objective makes dusk look like full daylight, and the instrument can easily double as a starter-viewer for amateur astronomy. Go for 7x50 or 8x50 – any more than 8 times magnification and you will not be able to hold it steady enough by hand. The only problem is they tend to be heavy. Small-size binoculars used to be too dark to be really useful in anything but full sunlight, but new lens technology has vastly improved their light-usage. Always try out binoculars before you buy, to check for good focus, proper coincidence of images, colour correction and focussing range. The focus should run from just beyond infinity to quite close in. Strangely the small binoculars seem better at close-work. If you want to use it to study insects, you need a closefocus of about 1 – 1.5 metres. What else you buy really depends upon what interests you. Some people have had enormous fun connecting small low-light cameras to their computers to record what wildlife passes through their garden after dark. Others have invested in night-vision technology and keep watch themselves. If you are mad-keen to learn which bats frequent your garden, you will need a bat detector, which uses a clever form of sound-manipulation to render the ultrasonic squeaks of the bats into audible frequencies in real-time. This sounds like magic, and therefore costs money. I wondered how much, and discovered that a basic one cost about €200 and prices climbed well into the thousand euro band. Further reading revealed that the “basic” one was quite hard to use and even harder to interpret. If you want something that says, “That’s a Daubenton’s Bat; that’s a Brown Longeared Bat; ...”, it will cost you a large slice of your pension. I decided just to enjoy my bats in their anonymity.

What’s happening in December
The weather this year has been seriously weird. Frost in April, drought in August and September, torrential rain in October. This has resulted in poor yields of fruit, nuts and fungi, although the warmth of summer did cheer us up during the Covid 19 depression. Now we have a lockdown or restricted Christmas to look forward to! Well, it will be something new to experience. Put up your decorations so everybody passing your home can see them – show the World we’re still here! The restrictions might cut down on the family gatherings, I guess, which will be a sadness to many but, I suspect, a relief to some. I shall be disappointed not to see the London fireworks on TV at New Year. Still, at least if all goes well I should see the New Year, which for a while was in some doubt! Good old French health service! Our hapless birds become even more visible now the leaves are off the trees. Sadly to cats and other predators as well as to us. Please don’t forget to feed them. Every little helps at this season.
Again, I wish you all a very merry Christmas and a happy, healthy, safe and Covid-free New Year. Mike
Mistletoe Hung in the Castle Hall
SO BEGINS A TRAGIC AND MOURNFUL SONG ABOUT A Mike George is our regularWEDDING DAY AND A LOST BRIDE, THE SORT OF DITTY contributor on THE VICTORIANS LOVED, ESPECIALLY AT CHRISTMAS wildlife and the countryside in France. He is a geologist and naturalist, living in But what is the significance of mistletoe, and where indeed does it fit Mistletoe has been regarded as something special for millennia. We know that the By Mike George the Jurassic area of the Charente into the scheme of things? Ancient Greeks regarded it as a fertility Mistletoe is a very odd plant indeed. It is halfway between a “proper” plant and a parasite. It is green, and can make its own nutrients by photosynthesis, the same as a normal, soil-rooted plant, but it draws additional sustenance from the tree on which it grows through a speciallyadapted root that finds its way into the phloem or water-carrying system of the tree and absorbs some of the nutrients that that is carrying. Only part of the nutrient is taken, but it can weaken the tree, especially if the tree is heavily infested. symbol, as did the Romans. The latter used it to decorate their houses at the festival of Saturnalia. The most famous adherents of mistletoe were the Celts and their Druidic priesthood. They regarded it as a magic plant, which could aid in all sorts of ceremonies and treatments. They found it on many types of trees, but only very rarely on Oak. Therefore any mistletoe on an Oak-tree was very soughtafter as being particularly efficacious. According to Roman historians, it was gathered with a gold-bladed knife or sickle, and caught on a fabric sheet before it could touch the ground. These Roman made a spear (or possibly an arrow) of mistletoe, with which he succeeded in arranging the killing of Baldur. This was, in Norse mythology, the beginning of the slide downhill to Ragnarok, the final battle that would destroy the gods. When Christianity came along, one way it tried to soften the trauma of conversion from paganism was to make up new myths to explain the parts plants played in the unfolding of the Christian message. They were on a pretty good wicket with The plant is spread mainly by birds, which eat the sticky seeds. Certain birds like the Mistle Thrush (which takes its name from the Mistletoe) are immune from the plant’s toxins. They cannot eat the hard seed, so either wipe it off on the bough where the tacky seed-pulp causes it to stay, or it passes though the bird’s digestive tract and emerges in the droppings. This is believed to explain the plant’s odd name. There is some disagreement, but the majority of etymologists derive “mistle” from the Anglo-Saxon for excrement, with “toe” deriving from the word for twig. At one time it was thought that the dung-route was the only way to produce a viable seed. This is now known not to be true, though a dung-carried seed will germinate more rapidly. Strangely, one of the only commercial uses for mistletoe (apart from charging exorbitant prices as a Christmas decoration) was that for centuries the seed-pulp was used to make bird-lime, a sticky substance that was spread on treetwigs to catch birds. There is even an old Latin proverb, which compares this with commentators were very much antiDruid, so they added sinister, telling little details, such as that the fabric sheet had to be held by a number of young virgin girls, and that the successful collection was celebrated by sacrificing a white oxen (or possibly a virgin). Lovable old Druids as found in Asterix were not on the Roman agenda! Quite what the Druids used their mistletoe for is not recorded. Mistletoe itself is somewhat toxic, though rarely fatal. Recent investigation has indicated a few alkaloids that may possibly be medically useful, but not much work has been done so far. It seems that mistletoe can absorb different extra alkaloids depending on the plant upon which it grows. Whether this had any significance for the Druids of course we do not know. It seems unlikely. Holly and even Ivy, but Mistletoe defeated them totally. They tried to suggest that the plant had originally been a tree, from which the Cross of Christ was made, and that it had been condemned to be smallwooded and insignificant ever since. Of course, Mistletoe had looked the same for millennia before the Crucifixion! In the end they gave up, and sort of shouldered it out of Christmas festivities. However, in York Minster, in that proud old Viking capital, a branch of mistletoe is said to be placed on the altar each Christmas. The Kissing Bunch, and kissing under the mistletoe, came much later, about the time of the Reformation, when Christmas and the involvement of saints was undergoing a lot of rethinking. This was when raffish Old Father Christmas re-entered the scene, and a few other dubious customs that had lain hidden for centuries were rediscovered. As we saw at the beginning, the ancient Greeks and Romans regarded mistletoe as a fertility symbol. This came back with a vengeance, The Kissing Bunch, and kissing under the mistletoe, came much later, about the time of the Reformation, when Christmas and the involvement of saints was undergoing a lot of rethinking the part the bird plays in spreading One thing that has been noted is that, in and now the white berries of mistletoe mistletoe, and states that Turdus ipse sibi the stomachs of some bog-bodies (corpses took on a new meaning.
