In the wilder districts of Scotland, wherever there is sufficient forest, martens are still far from uncommon; and they are comparatively abundant in parts of Scandinavia, France, Spain, Germany, Hungary, and Russia. Among the characteristics of the species, the most easily recognisable is the yellow or orange area on the throat; this part being white in the beech-marten. That these two animals are distinct species, and not merely local races of a single one, seems to be demonstrated by their occurrence in the same districts. How far eastwards the range of the marten extends does not appear to be ascertained. In Siberia the species is, however, represented by the closely allied sable (_M. zibellina_), which in turn gives place in North America to the American marten (_M. americana_). All three might perhaps, however, be regarded as geographical races of one and the same species. Martens are essentially forest-animals, which prefer evergreen trees, and are especially partial to woods where dead tree-trunks lie rotting on the ground or form natural bridges from one stem to another. Here they are as active as squirrels, and chase one another in the same sportive manner. Much of their prey is, however, taken on the ground, and they are deadly foes to hares, rabbits, pheasants, and partridges, as well as to small birds of all kinds. They are also reported to eat beech-mast, and if this be the case, berries may also very probably form a portion of their diet. The persistency with which a marten will follow the trail of a hare or a rabbit, even in deep snow, is a character the species possesses in common with the weasel tribe generally; and if it fail to pounce upon the unsuspecting victim in the first few springs, it will settle down to the chase as steadily as a beagle or a harrier. [Illustration] Martens are devoid of the unpleasant odour of the polecat, or foumart, and are therefore suitable for taming. In their native forests they associate in pairs, and make their nests high up in tall trees, selecting in some instances a hole in the stem, but in other cases taking possession of the deserted nests of wood-pigeons or other large birds, or occasionally the drey of a squirrel. In this nest are born early in the spring the six or seven young, which come into the world blind, and are tended by their parents with assiduous care; and they remain in its neighbourhood till they are nearly full grown. In North America it has been observed that once in about every eight or ten years martens more or less completely disappear from districts in which they are at other times abundant. Strange to say, there is no evidence of the prevalence of disease on such occasions; and it is certain that the martens do not migrate after the manner of lemmings. It has, however, been noticed by the trappers that just before their disappearance none of the martens in the district will take a bait, although at other times they are caught with comparative ease.
