I have since had many an uncomfortable moment at the thought of how many lovely songsters may have paid with their lives for that ungodly experiment; for my companion hailed me as a master Nimrod from the New World; and when I refused, on the plea of bad luck, to teach him the call, I heard him give a distressingly good imitation of it. Yet the experiment seemed to prove that everywhere birds quickly catch the contagion of excitement; that in many cases they respond to a call because it stirs their anger or curiosity rather than because it conveys any definite summons for help or warning of danger.
When you open your ears among the beasts you hear precisely the same story; that is, certain cries apparently have definite meaning, like the accented haw of a crow, while others convey and also spread a wild emotion. Of all beasts, the wolves are perhaps the keenest, the most intelligent, and these seem to have definite calls for food or help or hunting or assembly. Such calls are [[26]]strictly tribal, I think, like the dialects of Indians, since the call of a coyote is quite different from the call of a timber wolf even when both intend to convey the same meaning. A friend of mine, an excellent mimic, who spent many years in the West, has shot more than a score of coyotes after drawing them within range by sending forth the food-call in winter; but though he knows also the food-call of the timber wolf, he has never once deceived these larger brutes by his imitation of it; nor has he ever seen a wolf of one species respond to the food or hunting call of another.
Like most other wild animals, timid or savage, the sensitive wolves all respond, but much more warily than the birds, to almost any inarticulate cry expressive of emotional excitement; just as your dog, who is yesterday’s wolf, grows uneasy when you whine in your nose like a distressed puppy, or leaps up, ready to fly out of door or window, when a wild ki-yi breaks out in the distance. Indeed, it is easier to keep a boy from a fire than a dog from a crowd or excitement of any kind; and the same is true of their wild relatives, though the wariness of the latter keeps them hidden where you cannot follow their action. The greatest commotion I ever witnessed in a timber-wolf pack was occasioned by the moaning howl of a wounded wolf on a frozen lake in midwinter. [[27]]It was a cry utterly unlike anything I had ever recorded up to that time, and every time they heard it the grim beasts ran wildly here and there, howling like lunatics. Then, when the wounded one grew quiet, they would approach and sniff him all over; after which some would sit on their tails and watch him closely, while others circled about on the ice, using their noses like hounds in search of a lost trail.
Occasionally, when I have had these uncanny brutes near me in the North, I have tried to call them or make them answer by giving what seemed to me a very good imitation of their cries; but seldom has a howl of mine been returned. On the contrary, the brutes almost always stop their howling whenever I begin to talk wolf-talk, as if they were listening and saying, “What under the moon is that now?” Then old Tomah, the Indian, comes out of his blanket and gives a howl exactly like mine, but with something in it which I cannot fathom or master, and instantly from the snow-filled woods comes back the wild wolf answer.
Likewise, I have called moose in many different localities, and am persuaded that it makes very little difference what kind of whine or grunt or bellow you utter, since anything resembling a moose-call will do the trick if you know how to [[28]]put the proper feeling into your voice. After listening carefully to many callers, I note this characteristic difference: that one man invariably makes the game wary, suspicious, fearful, no matter how finely he calls; while another in the same place, with the same trumpet and apparently with the same call, manages to put something into his voice, something primal, emotional and essentially animal, which brings a bull moose hurriedly to investigate. Thus it happens that the worst caller I ever heard—worst in that he had no sense, no cunning, no knowledge of moose habits, and uttered a blatant, monstrous roar unlike anything a sane man ever heard in the heavens above or the earth beneath—was still the most successful in getting his game into the open. Three nights in succession I heard him call in a region where moose were over-shy from much hunting, and where my own imitation of the animal’s natural voice brought small response. In that time fourteen bulls answered him, all that were within hearing, I think; and every one of the great brutes threw caution to the dogs and came out on the jump.
From such observations, and from others which I have not chronicled, I judge that the higher orders of birds and beasts have a few calls which stand for definite things, or mental images of [[29]]things, but that their ordinary cries merely project an emotion or excitement in such a way that it stirs a similar emotion in other birds or beasts of the same species; just as the sound of hearty laughter invariably stirs the feeling of mirth in men who hear it, or any inarticulate cry of fear sets human feet in motion—toward the cry if the hearer be brave, or away from it if he be of cowardly disposition. Yet even among men, who by civilization have lost some of their natural virtues, the primal impulse still lives. Like the wolf or the raccoon, the man’s first impulse is to rush to his distressed or excited fellows. If he turns and runs the other way, it means simply that his artificial habit or training has deadened his natural instincts.
In speaking of “man” here I refer to the genus homo, not to the male specimen thereof. Among brutes most of the natural instincts are the same in both sexes; they vary in degree, not in kind, and the instincts of the female are commonly the stronger or keener. Yet I have noticed, or think I have noticed, this difference: when a cry of distress is uttered in the woods, the first bird or beast to appear is almost always a female; but the male is quicker on his toes at a battle-yell or a senseless clamor.
This last is a personal impression, and cannot well be verified. The only record I have which [[30]]might pass for evidence in the matter comes from my observation of the crows. In the spring many of these questionable birds indulge their taste for eggs or tender flesh and soon become incurable nest-robbers; and for that reason I often shoot them, to save other and more useful birds. The method is very simple: one hides and calls, and takes the crows as they appear in swift flight, the number shot being commonly limited to one or two at a time. And I have observed repeatedly, at different times and in different localities, that when I use the distress-call of a young crow as a decoy, the first to appear over the tree-tops is a female. This is the common rule, with occasional exceptions to point or emphasize it. But whenever I clamor like a crow that has discovered an owl, or send forth a senselessly excited hawing, almost invariably the first crow to come whooping over is a long-winged and glossy old male.
Does it seem to you like thoughtless barbarity on my part to kill crows in this fashion? Perhaps it is barbarous; I do not quite know; but it certainly is not thoughtless. One cannot blame the crows for their taste in eggs or nestlings; but one must note that they destroy an enormous number of insectivorous birds, and that the harm they do in this respect outweighs their usefulness in destroying field-mice and beetles. I write this [[31]]with regret; for I admire the crow, and consider him as, of all birds, the most intelligent and the most considerate of his own kind. I know that it is a moot question whether the crow does more harm or good, and that some naturalists have settled it in his favor; but I have too often caught him plundering nests in the springtime to be much impressed by his alleged usefulness at other seasons. I think that he may have been once useful in preserving the so-called balance of nature; but that balance is now dangerously unequal. The crow has flourished even in well-settled regions, thanks to his superior wit, while other useful birds have fearfully diminished, and this at a time when our orchards and gardens call more and more insistently for their help. Because of his disproportionate numbers the crow now appears to me, like our destructive and useless cats, as a positive menace in a country where he once occupied a modest or inconspicuous place—such a place as he still occupies in the wilderness, where I meet him but rarely, and where I am glad to leave him in peace, since he does not seriously interfere with his more beautiful or more useful neighbors. But we are wandering from the dim trail of animal communication, which we set out to follow.
The inarticulate but variously accented cries of which we have spoken constitute the only animal [[32]]language to which our naturalists have thus far paid any attention; and doubtless some of them would object to the use of the word “language” in such a connection. In all matters of real natural history, however (real, that is, in the sense of dealing at first hand with individual birds or beasts), I am much more inclined to listen to old Tomah, who says, when I ask him whether animals can talk: “Talk? Course he kin talk! Eve’ting talk in hees own way. Hear me now make-um dat young owl talk.” And, stepping outside the circle of camp-fire light, Tomah utters a hoot, which is answered at a distance every time he tries it. After parleying with the stranger in this tentative fashion, Tomah sends forth a different call; and immediately, as if in ready acceptance of an invitation, a barred owl glides like a gray shadow into a tree over our heads. I have heard that same old Indian use horned-owl talk, wolf and beaver and woodpecker talk, and several other dialects of the wood folk, in the same fascinating and convincing way.
