Most people seem to confuse shrews with mice; but, indeed, our small combatants are widely different creatures from those timid little beasts; they belong to a wholly different group of mammals. Mice are rodents9, descendants of the same common ancestor with the rats and dormice, and not remotely related to the squirrels and the rabbits. Shrews, on the other hand, are insectivores, first cousins of the moles10, the hedgehogs, and the desmans. Externally, it is true, they resemble considerably12 the mice and voles; but those who have followed the course of recent natural history must be aware by this time that “appearances are deceitful.” If an animal looks very much like something else, the chances are that it is altogether different. This is particularly the case with the insectivores and the marsupials, each of which great groups has independently developed a series of forms absurdly like the mice, the squirrels, the porcupines13, and the jerboas, because each fills approximately the same place in nature. For example, small mammals which creep about among grass and matted herbage are likely to assume a mouse-like shape. This has happened among rodents in the case of the mice and field-voles, among insectivores in the case of the shrews, and among Australian marsupials in the case of the pouched14 kangaroo-mice. Our English shrew is a pretty little creature of this common type, with thick soft fur like a mouse’s, only a trifle redder, and so mousey in shape that it is seldom discriminated15 from the true mice, save by naturalists16 and gamekeepers. Even externally, however, it differs much from mice in its long pointed17 snout—a marked insectivorous feature—as well as in its square and abruptly18 cut-off tail, where the mouse’s is rounded, tapering19, and slender. When you come to the teeth and internal anatomy20, however, the creature is an insectivore, displaying at once quite a separate character.
Mice, as everybody knows, feed mainly on seeds and grains, though they are fairly omnivorous21, and do not despise either bees or beetles22. But the shrew, less promiscuous23, eschews24 all vegetable foods; he makes his diet entirely25 of insects, worms, and slugs, of which he devours26 an incredible number. Hence he haunts for the most part dry fields and gardens, where such prey27 is abundant. His preference is also for a soft sandy or light loamy soil, in which he can burrow28 with ease with the muzzle29 alone, for his slender feet are ill adapted for digging through hard earth or clay. A relative of the mole11, he makes long runs, like his cousin, through the soft surface-soil in search of insects; but, unlike the mole again, he has preserved his small, keen eyes intact, and lives, on the whole, as much above ground as beneath it. Yet his cousinship stands him in small stead with his big purblind30 relation; for moles catch and eat shrews in considerable numbers. This is not to be wondered at, perhaps, when one reflects that the unnatural31 shrews also eat one another. Cannibalism32, indeed, is an unamiable trait common to man and the insectivores. Weasels, owls33, and cats are also great shrew-killers; though, strange to say, the shrew, when killed, is by no means always eaten. I put this down in the main to the powerful scent-glands, which run along the side of the body, or occur at the root of the tail, in most species of shrew, and which secrete34 a very strong and odorous liquid. This liquid, I fancy, is partly protective, partly attractive to the opposite sex. It would seem to be distasteful to outsiders, but not unpleasant to insectivores themselves, for cats will kill a shrew from pure love of sport, or by mistake for a mouse, but will seldom or never eat it, whereas shrews themselves and moles have no such prejudice. Owls, also, eat shrews, in spite of their flavour. I believe such sexually attractive scents35 almost always coexist with the pugnacious temperament36. All musky-perfumed animals fight savagely37 with one another for possession of their females, as do also those with marked frills or top-knots.
Shrews, though comparatively seldom seen by incurious eyes, abound38 by myriads39 in most parts of England. Every summer they increase sevenfold; but as autumn approaches, and food grows scarce, they die off in their thousands from cold and hunger, as I gather. So many of them then strew40 the footpaths41 in sandy districts that country people have a quaint42 superstition43 about them; they say a shrew cannot cross a church-path without dying instantly. What constitutes a church-path is somebody having once gone to church along it. The truth is, dead shrews abound equally in the grass and thickets44; but, of course, only those are seen which happen to die in the open. This is but one out of many hundred odd superstitions45 about the shrew, which may be regarded, indeed, as the most wizard-like animal now left in England.
