In the rutting season there is a good deal of desperate fighting between jealous males; but this business disposed of a nursery nest or "hover" is constructed of rushes and grass, and lined with the soft, purple flower panicles of the great reed. Here, in the winter, the bitch Otter brings forth her two or three blind young. They are already covered with a fine downy fur. Both parents hunt to provide them with food, and in due course they are taken out one night to be taught the way of life in the waters. The partnership of the parents is only temporary, and as soon as the young ones are capable of taking care of themselves, the old dog Otter goes to live by himself. The mother remains with her family until the rutting season returns, when she also departs to find another mate. In Norfolk the nursery is frequently found on the surface, in the great reed-beds.
The chief enemy of the Otter is the river-keeper on waters that are preserved for fishing, who has always his traps set for them. This is somewhat strange when it is remembered that the Otter is also an animal of the chase, packs of Otter-hounds still being kept like fox-hounds in certain districts, though the packs are by no means so numerous as in former times. The flesh of the Otter is rank and fishy-flavoured, and therefore not in demand for human food; but there are many records showing that it has been esteemed for use on days when the rules of the Church permitted fish only to be eaten, the clerical casuists easily finding that as it spends most of its active life in the water and has a fishy taste, it must be a kind of a fish! Readers of dear old Izaak Walton will remember the Otter-hunter's reply when Piscator asks him whether he hunts a beast or a fish. The Huntsman says—
"Sir, it is not in my power to resolve you; yet I leave it to be resolved by the College of Carthusians, who have made vows never to eat flesh. But I have heard the question hath been debated among many great clerks, and they seem to differ about it; yet most agree that her tail is fish; and if her body be fish too, then I may say that a fish will walk upon land (for an Otter does so), sometimes five or six or ten miles in a night."
More recently Pennant says he saw an Otter in the kitchen of the Carthusian monastery near Dijon, being prepared for dinner.
There have been many cases of tame Otters who hunted streams for fish for the benefit of their owner, to whom they return on hearing a whistle or other signal. Some years ago an interesting account appeared in The Field of an Otter whelp that had been mothered by an Otter-hound, afterwards hunting its own kind with the pack.
Pine Marten (Mustela martes, Linn.).
The Pine Marten or Marten Cat was formerly quite a common woodland beast, but owing to the onslaughts of the gamekeeper and the high prices paid for a skin, it is now, so far as southern and midland England is concerned, extinct. In the wilder parts of the Peak district, the North of England, Wales, Scotland, and Ireland, however, it still exists, though in small and ever decreasing numbers in most places. In the Lake District it was quite recently reported to be fairly common even. The name Pine Marten is a misnomer in so far as it indicates that the animal is at all restricted to pine woods; and it is probable that in the past it led to confusion, for in all the natural histories published up to a late date in the nineteenth century, Britain was credited with an additional species, the Beech Marten (Mustela foina). The two species are much alike, and the practice appears to have been to record those found in pine woods as M. martes and those in other woods as M. foina! Bell, indeed, though he expressly states his disbelief in our possession of two species of Marten, refers to the white-throated form as the Beech Marten or Common Marten and says it is more frequently met with than the yellow-throated form or Pine Marten. The truth is that there is a white-throated Mustela foina in Europe and Asia, but it does not reach northward so far as Sweden, Norway, or the British Isles. The white examples found in this country are old animals from which the yellow tint has faded.
The Pine Marten may be described as resembling roughly the better known Polecat, but with longer legs, a broader, more triangular head with sharp-pointed muzzle, and a longer, more bushy tail. Its entire length is between twenty-five and thirty inches, of which from nine to twelve inches are contributed by the tail. Its colour is a rich dark brown, except on the throat and breast which vary from orange through yellow to creamy-white. The middle of the back and the exposed sides of the legs and feet are darker than the rest, whilst beneath the tint approaches grey. The superficial colour is provided by the long upper, glossy fur, but beneath this is a finer, softer fur of shorter reddish-grey hairs tipped with yellow. The eyes are large, black, and prominent, the ears broad, open, and rounded at the tips. Like all the other members of the family Mustelidæ, the Marten is provided with glands near the base of the tail. It is these which enable the Skunk and the Polecat to disgust their enemies; but in the case of the Marten the secretion is merely of a musky odour and not objectionable; in consequence one of its old English names was Sweet Marten to distinguish it from the Foulmart or Polecat.
The habits of the Pine Marten are mainly arboreal, for which the long slender body and sharp long claws specially fit it, whilst the long bushy tail is useful as a balancer in negotiating slender branches in the pursuit of birds, or in reaching their nests for eggs. All the same, the Marten is at times very active on the ground where he destroys rats, mice, voles, rabbits, hares, game-birds, and domestic poultry large and small. He is even accused of attacking lambs and stealing trout from the fishing boats. He has also a taste for bilberries, strawberries, cherries, and raspberries; and C. St. John tells an interesting story in this connection which illustrates the Marten's cleverness in hiding. He says: "I saw in my garden in Inverness-shire that some animal came nightly to the raspberry bushes; the track appeared like that of a rabbit or hare, but as I also saw that the animal climbed the bushes, I knew it could be neither of these. Out of curiosity, I set a trap for the marauder; the next morning, on going to look at it very early, I could see nothing on the spot where I had put my trap but a heap of leaves, some dry and some green; I was just going to move them with my hand, when I luckily discovered a pair of bright eyes peering sharply out of the leaves, and discovered that I had caught a large Marten, who, finding that he could not escape, had collected all the leaves within his reach, and had quite concealed himself under them. The moment he found that he was discovered, he attacked me most courageously, as the Marten always does, fighting to the last. I had other opportunities of satisfying myself that this animal is a great fruit-eater, feeding much on the wild raspberries, and even blackberries, that grow in the woods." It also robs beehives of their honey.
