GATHERED BY THE WAY

I. THE TRAINING OF WILD ANIMALS

I WAS reminded afresh of how prone we all are to regard the actions of the lower animals in the light of our own psychology on reading “The Training of wild Animals,” by Bostock, a well-known animal-trainer. Bostock evidently knows well the art of training animals, but of the science of it he seems to know very little. That is, while he is a successful trainer, his notions of animal psychology are very crude. For instance, on one page he speaks of the lion as if it were endowed with a fair mea­sure of human intelligence, and had notions, feel­ings, and thoughts like our own; on the next page, when he gets down to real business, he lays bare its utter want of these things. He says a lion born and bred in captivity is more difficult to train than one caught from the jungle. Then he gives rein to his fancy. “Such a lion does not fear man; he knows his own power. He regards man as an inferior, with an attitude of disdain and silent hauteur.” “He accepts his food as tribute, and his care as homage due.” “He is aristocratic in his independence.”

“Deep in him — so deep that he barely realizes its existence — slumbers a desire for freedom and an unutterable longing for the blue sky and the free air.” When his training is begun, “he meets it with a reserved majesty and silent indifference, as though he had a dumb realization of his wrongs.” All this is a very human way of looking at the matter, and is typical of the way we all — most of us — speak of the lower animals, defining them to ourselves in terms of our own mentality, but it leads to false notions about them. We look upon an animal fretting and struggling in its cage as longing for freedom, pictur­ing to itself the joy of the open air and the free hills and sky, when the truth of the matter undoubtedly is that the fluttering bird or restless fox or lion sim­ply feels discomfort in confinement. Its sufferings are physical, and not mental. Its instincts lead it to struggle for freedom. It reacts strongly against the barriers that hold it, and tries in every way to overcome them. Freedom, as an idea, or a concep­tion of a condition of life, is, of course, beyond its capacity.

Bostock shows how the animal learns entirely by association, and not at all by the exercise of thought or reason, and yet a moment later says: “The ani­mal is becoming amenable to the mastery of man, and in doing so his own reason is being developed,” which is much like saying that when a man is prac­ticing on the flying trapeze his wings are being developed. The lion learns slowly through association — through repeated sense impressions. First a long stick is put into his cage. If this is destroyed, it is replaced by another, until he gets used to it and tol­erates its presence. Then he is gently rubbed with it at the hands of his keeper. He gets used to this and comes to like it. Then the stick is baited with a piece of meat, and in taking the meat the animal gets still better acquainted with the stick, and so ceases to fear it. When this stage is reached, the stick is shortened day by day, “until finally it is not much longer than the hand.” The next step is to let the hand take the place of the stick in the stroking process. “This is a great step taken, for one of the most difficult things is to get any wild animal to allow himself to be touched with the human hand.” After a time a collar with a chain attached is slipped around the lion’s neck when he is asleep. He is now chained to one end of the cage. Then a chair is introduced into the cage; whereupon this king of beasts, whose reason is being developed, and who has such clear notions of inferior and superior, and who knows his own powers, usually springs for the chair, seeking to demolish it. His tether prevents his reaching it, and so in time he tolerates the chair. Then the trainer, after some preliminary feints, walks into the cage and seats himself in the chair. And so, inch by inch, as it were, the trainer gets control of the animal and subdues him to his purposes, not by appealing to his mind, for he has none, but by impressions upon his senses.

“Leopards, panthers, and jaguars are all trained in much the same manner,” and in putting them through their tricks one invariable order must be observed: “Each thing done one day must be done the next day in exactly the same way; there must be no deviation from the rule.” Now we do not see in this fact the way of a thinking or reflecting being, but rather the way of a creature governed by instinct or unthinking intelligence. An animal never learns a trick in the sense that man learns it, never sees through it or comprehends it, has no image of it in its mind, and no idea of the relations of the parts of it to one another; it does it by reason of repetition, as a creek wears its channel, and probably has no more self-knowledge or self-thought than the creek has. This, I think, is quite contrary to the popular notion of animal life and mentality, but it is the con­clusion that I, at least, cannot avoid after making a study of the subject.

II. AN ASTONISHED PORCUPINE

One summer, while three young people and I were spending an afternoon upon a mountain-top, our dogs treed a porcupine. At my suggestion the young man climbed the tree — not a large one — to shake the animal down. I wished to see what the dogs would dg with him, and what the “quill-pig” would do with the dogs. As the climber advanced the rodent went higher, till the limb he clung to was no larger than one’s wrist. This the young man seized and shook vigorously. I expected to see the slow, stupid porcupine drop, but he did not. He only tightened his hold. The climber tightened his hold, too, and shook the harder. Still the bundle of quills did not come down, and no amount of shaking could bring it down. Then I handed a long pole up to the climber, and he tried to punch the animal down. This attack in the rear was evidently a surprise; it produced an impression different from that of the shaking. The porcupine struck the pole with his tail, put up the shield of quills upon his back, and assumed his best attitude of defense. Still the pole persisted in its persecution, regardless of the quills; evidently the animal was astonished: he had never had an experience like this before; he had now met a foe that despised his terrible quills. Then he began to back rapidly down the tree in the face of his enemy. The young man’s sweetheart stood below, a highly interested spectator. “Look out, Sam, he’s coming down!” “Be quick, he ‘s gaining on you!” “Hurry, Sam!” Sam came as fast as he could, but he had to look out for his foot­ing, and his antagonist did not. Still, he reached the ground first, and his sweetheart breathed more easily. It looked as if the porcupine reasoned thus: “My quills are useless against a foe so far away; I must come to close quarters with him.” But, of course, the stupid creature had no such mental process, and formed no such purpose. He had found the tree unsafe, and his instinct now was to get to the ground as quickly as possible and take refuge among the rocks. As he came down I hit him a slight blow over the nose with a rotten stick, hoping only to con­fuse him a little, but much to my surprise and morti­fication he dropped to the ground and rolled down the hill dead, having succumbed to a blow that a woodchuck or a coon would hardly nave regarded at all. Thus does the easy, passive mode of defense of the porcupine not only dull his wits, but it makes frail and brittle the thread of his life. He has had no struggles or battles to harden and toughen him.

That blunt nose of his is as tender as a baby’s, and he is snuffed out by a blow that would hardly bewil­der for a moment any other forest animal, unless it be the skunk, another sluggish non-combatant of our woodlands. Immunity from foes, from effort, from struggle is always purchased with a price.

Certain of our natural history romancers have taken liberties with the porcupine in one respect: they have shown him made up into a ball and roll­ing down a hill. One writer makes him do this in a sportive mood; he rolls down a long hill in the woods, and at the bottom he is a ragged mass of leaves which his quills have impaled — an appari­tion that nearly frightened a rabbit out of its wits. Let any one who knows the porcupine try to fancy it performing a feat like this!

Another romancer makes his porcupine roll him­self into a ball when attacked by a panther, and then on a nudge from his enemy roll down a snowy incline into the water. I believe the little European hedge­hog can roll itself up into something like a ball, but our porcupine does not. I have tried all sorts of tricks with him, and made all sorts of assaults upon him, at different times, and I have never yet seen him assume the globular form. It would not be the best form for him to assume, because it would partly expose his vulnerable under side. The one thing the porcupine seems bent upon doing at all times is to keep right side up with care. His attitude of defense is crouching close to the ground, head drawn in and pressed down, the circular shield of large quills upon his back opened and extended as far as possible, and the tail stretched back rigid and held close upon the ground. “Now come on,” he says, “if you want to.” The tail is his weapon of active defense; with it he strikes upward like lightning, and drives the quills into whatever they touch. In his chapter called “In Panoply of Spears,” Mr. Roberts paints the porcu­pine without taking any liberties with the creature’s known habits. He portrays one characteristic of the porcupine very felicitously: “As the porcupine made his resolute way through the woods, the man­ner of his going differed from that of all the other kindreds of the wild. He went not furtively. He had no particular objection to making a noise. He did not consider it necessary to stop every little while, stiffen himself to a monument of immobility, cast wary glances about the gloom, and sniff the air for the taint of enemies. He did not care who knew of his coming, and he did not greatly care who came. Behind his panoply of biting spears he felt himself secure, and in that security he moved as if he held in fee the whole green, shadowy, perilous woodland world.”

III. BIRDS AND STRINGS

A college professor writes me as follows:

 “Watching this morning a robin attempting to carry off a string, one end of which was caught in a tree, I was much impressed by his utter lack of sense. He could not realize that the string was fast, or that it must be loosened before it could be car­ried off, and in his efforts to get it all in his bill he wound it about a neighboring limb. If as little sense were displayed in using other material for nests, there would be no robins’ nests. It impressed me more than ever with the important part played by instinct.”

Who ever saw any of our common birds dis­play any sense or judgment in the handling of strings? Strings are comparatively a new thing with birds; they are not a natural product, and as a matter of course birds blunder in handling them. The oriole uses them the most successfully, often attaching her pensile nest to the branch by their aid. But she uses them in a blind, childish way, winding them round and round the branch, often getting them looped over a twig or hopelessly tangled, and now and then hanging herself with them, as is the case with other birds. I have seen a sparrow, a cedar-bird, and a robin each hung by a string it was using in the building of its nest. Last spring, in Spokane, a boy brought me a desiccated robin, whose feet were held together by a long thread hopelessly snarled. The boy had found it hanging to a tree.

I have seen in a bird magazine a photograph of an oriole’s nest that had a string carried around a branch apparently a foot or more away, and then brought back and the end woven into the nest. It was given as a sample of a well-guyed nest, the dis­coverer no doubt looking upon it as proof of an oriole’s forethought in providing against winds and storms. I have seen an oriole’s nest with a string carried around a leaf, and another with a long looped string hanging free. All such cases simply show that the bird was not master of her material; she bungled; the trailing string caught over the leaf or branch, and she drew both ends in and fastened them regardless of what had happened. The inci­dent only shows how blindly instinct works.

Twice I have seen cedar-birds, in their quest for nesting-material, trying to carry away the strings that orioles had attached to branches. According to our sentimental “School of Nature Study,” the birds should have untied and unsnarled the strings in a human way, but they did not; they simply tugged at them, bringing their weight to bear, and tried to fly away with the loose end.

In view of the ignorance of birds with regard to strings, how can we credit the story told by one of our popular nature writers of a pair of orioles that deliberately impaled a piece of cloth upon a thorn in order that it might be held firmly while they pulled out the threads? When it came loose, they refastened it. The story is incredible for two reasons: (1) the male oriole does not assist the female in building the nest; he only furnishes the music; (2) the whole proceeding implies an amount of reflection and skill in dealing with a new problem that none of our birds possess. What experience has the race of orioles had with cloth, that any member of it should know how to unravel it in that way? The whole idea is absurd.

IV. MIMICRY

To what lengths the protective resemblance the­ory is pushed by some of its expounders! Thus, in the neighborhood of Rio Janeiro there are two species of hawks that closely resemble each other, but one eats only insects and the other eats birds.

Mr. Wallace thinks that the bird-eater mimics the insect-eater, so as to deceive the birds, which are not afraid of the latter. But if the two hawks look alike, would not the birds come to regard them both as bird-eaters, since one of them does eat birds? Would they not at once identify the harmless one with their real enemy and thus fear them both alike? If the latter were newcomers and vastly in the minor­ity, then the ruse might work for a while. But if there were ten harmless hawks around to one dangerous one, the former would quickly suffer from the char­acter of the latter in the estimation of the birds. Birds are instinctively afraid of all hawk kind.

Wallace thinks it may be an advantage to cuckoos, a rather feeble class of birds, to resemble the hawks, but this seems to me far-fetched. True it is, if the sheep could imitate the wolf, its enemies might keep clear of it. Why, then, has not this resemblance been brought about? Our cuckoo is a feeble and defenseless bird also, but it bears no resemblance to the hawk. The same can be said of scores of other birds.

Many of these close resemblances among different species of animals are no doubt purely accidental, or the result of the same law of variation acting under similar conditions. We have a hummingbird moth that so closely in its form and flight and man­ner resembles a hummingbird, that if this resem­blance brought it any immunity from danger it would be set down as a clear case of mimicry. There is such a moth in England, too, where no humming­bird is found. Why should not Nature repeat herself in this way? This moth feeds upon the nectar of flowers like the hummingbird, and why should it not have the hummingbird’s form and manner?

Then there are accidental resemblances in nature, such as the often-seen resemblance of knots of trees and of vegetables to the human form, and of a cer­tain fungus to a part of man’s anatomy. We have a fly that resembles a honey-bee. In my bee-hunting days I used to call it the “mock honey-bee.” It would come up the wind on the scent of my bee box and hum about it precisely like a real bee. Of course it was here before the honey-bee, and has been evolved quite independently of it. It feeds upon the pollen and nectar of flowers like the true bee, and is, therefore, of similar form and color. The honey-bee has its enemies; the toads and tree-frogs feed upon it, and the kingbird captures the slow drone.

When an edible butterfly mimics an inedible or noxious one, as is frequently the case in the tropics, the mimicker is no doubt the gainer.

It makes a big difference whether the mimicker is seeking to escape from an enemy, or seeking to deceive its prey. I fail to see how, in the latter case, any disguise of form or color could be brought about.

Our shrike, at times, murders little birds and eats out their brains, and it has not the form, or the color, or the eye of a bird of prey, and thus probably deceives its victims, but there is no reason to believe that this guise is the result of any sort of mimicry.

V. THE COLORS OF FRUITS

Mr. Wallace even looks upon the nuts as pro­tectively colored, because they are not to be eaten. But without the agency of the birds and the squir­rels, how are the heavy nuts, such as the chestnut, beechnut, acorn, butternut, and the like, to be scat­tered? The blue jay is often busy hours at a time in the fall, planting chestnuts and acorns, and red squirrels carry butternuts and walnuts far from the parent trees, and place them in forked limbs and holes for future use. Of course, many of these fall to the ground and take root. If the protective colora­tion of the nuts, then, were effective, it would defeat a purpose which every tree and shrub and plant has at heart, namely, the scattering of its seed. I notice that the button-balls on the sycamores are protectively colored also, and certainly they do not crave concealment. It is true that they hang on the naked trees till spring, when no concealment is possible. It is also true that the jays and the crows carry away the chestnuts from the open burrs on the trees where no color scheme would conceal them. But the squir­rels find them upon the ground even beneath the snow, being guided, no doubt, by the sense of smell.

The hickory nut is almost white; why does it not seek concealment also? It is just as helpless as the others, and is just as sweet-meated. It occurs to me that birds can do nothing with it on account of its thick shell; it needs, therefore, to attract some four-footed creature that will carry it away from the par­ent tree, and this is done by the mice and the squir­rels. But if this is the reason of its whiteness, there is the dusky butternut and the black walnut, both more or less concealed by their color, and yet having the same need of some creature to scatter them.

The seeds of the maple, and of the ash and the linden, are obscurely colored, and they are winged; hence they do not need the aid of any creature in their dissemination. To say that this is the reason of their dull, unattractive tints would be an expla­nation on a par with much that one hears about the significance of animal and vegetable coloration. Why is corn so bright colored, and wheat and barley so dull, and rice so white? No doubt there is a reason in each case, but I doubt if that reason has any relation to the surrounding animal life.

The new Botany teaches that the flowers have color and perfume to attract the insects to aid in their fertilization — a need so paramount with all plants, because plants that are fertilized by aid of the wind have very inconspicuous flowers. Is it equally true that the high color of most fruits is to attract some hungry creature to come and eat them and thus scatter the seeds? From the dwarf cornel, or bunch-berry, in the woods, to the red thorn in the fields, every fruit-bearing plant and shrub and tree seems to advertise itself to the passer-by in its bright hues. Apparently there is no other use to the plant of the fleshy pericarp than to serve as a bait or wage for some animal to come and sow its seed. Why, then, should it not take on these allur­ing colors to help along this end? And yet there comes the thought, may not this scarlet and gold of the berries and tree fruits be the inevitable result of the chemistry of ripening, as it is with the autumn foliage? What benefit to the tree, directly or in­directly, is all this wealth of color of the autumn? Many of the toadstools are highly colored also; how do they profit by it? Many of the shells upon the beach are very showy; to what end? The cherry-birds find the pale ox-hearts as readily as they do the brilliant Murillos, and the dull blue cedar berries and the duller drupes of the lotus are not concealed from them nor from the robins. But it is true that the greenish white grapes in the vineyard do not suffer from the attacks of the birds as do the blue and red ones. The reason probably is that the birds regard them as unripe. The white grape is quite recent, and the birds have not yet “caught on.”

Poisonous fruits are also highly colored; to what end? In Bermuda I saw on low bushes great masses of what they called “pigeon-berries” of a brilliant yellow color and very tempting, yet I was assured they were poisonous. It would be interesting to know if anything eats the red berries of our wild turnip or arum. I doubt if any bird or beast could stand them. Wherefore, then, are they so brightly colored? I am also equally curious to know if any­thing eats the fruit of the red and white baneberry and the blue cohosh.

The seeds of some wild fruit, such as the climbing bitter-sweet, are so soft that it seems impossible they should pass through the gizzard of a bird and not be destroyed.

The fruit of the sumac comes the nearest to being a cheat of anything I know of in nature — a collec­tion of seeds covered with a flannel coat with just a perceptible acid taste, and all highly colored. Unless the seed itself is digested, what is there to tempt the bird to devour it, or to reward it for so doing?

In the tropics one sees fruits that do not become bright colored on ripening, such as the breadfruit, the custard apple, the naseberry, the mango. And tropical foliage never colors up as does the foliage of northern trees.

VI. INSTINCT

Many false notions seem to be current in the popular mind about instinct. Apparently, some of our writers on natural history themes would like to discard the word entirely. Now instinct is not opposed to intelligence; it is intelligence of the unlearned, unconscious kind, — the intelligence in­nate in nature. We use the word to distinguish a gift or faculty which animals possess, and which is independent of instruction and experience, from the mental equipment of man which depends mainly upon instruction and experience. A man has to be taught to do that which the lower animals do from nature. Hence the animals do not progress in knowledge, while man’s progress is almost limitless. A man is an animal born again into a higher spirit­ual plane. He has lost or shed many of his animal instincts in the process, but he has gained the ca­pacity for great and wonderful improvement.

Instinct is opposed to reason, to reflection, to thought, — to that kind of intelligence which knows and takes cognizance of itself. Instinct is that lower form of intelligence which acts through the senses, — sense perception, sense association, sense memory, — which we share with the animals, though their eyes and ears and noses are often quicker and keener than ours. Hence the animals know only the present, visible, objective world, while man through his gift of reason and thought knows the inward world of ideas and ideal relations.

An animal for the most part knows all that it is necessary for it to know as soon as it reaches ma­turity; what it learns beyond that, what it learns at the hands of the animal-trainer, for instance, it learns slowly, through a long repetition of the process of trial and failure. Man also achieves many things through practice alone, or through the same process of trial and failure. Much of his manual skill comes in this way, but he learns certain things through the exercise of his reason; he sees how the thing is done, and the relation of the elements of the problem to one another. The trained animal never sees how the thing is done, it simply does it auto­matically, because certain sense impressions have been stamped upon it till a habit has been formed, just as a man will often wind his watch before going to bed, or do some other accustomed act, without thinking of it.

The bird builds her nest and builds it intelli­gently, that is, she adapts means to an end; but there is no reason to suppose that she thinks about it in the sense that man does when he builds his house. The nest-building instinct is stimulated into activity by outward conditions of place and climate and food supply as truly as the growth of a plant is thus stimulated.

As I look upon the matter, the most wonderful and ingenious nests in the world, as those of the weaver-birds and orioles, show no more independent self-directed and self-originated thought than does the rude nest of the pigeon or the cuckoo. They evince a higher grade of intelligent instinct, and that is all. Both are equally the result of natural prompt­ings, and not of acquired skill, or the lack of it. One species of bird will occasionally learn the song of another species, but the song impulse must be there to begin with, and this must be stimulated in the right way at the right time. A caged English spar­row has been known to learn the song of the canary caged with or near it, but the sparrow certainly inherits the song impulse. One has proof of this when he hears a company of these sparrows sitting in a tree in spring chattering and chirping in unison, and almost reaching an utterance that is song-like. Our cedar-bird does not seem to have the song im­pulse, and I doubt if it could ever be taught to sing. In like manner our ruffed grouse has but feeble vocal powers, and I do not suppose it would learn to crow or cackle if brought up in the barn-yard. It expresses its joy at the return of spring and the mating season in its drum, as do the woodpeckers.

The recent English writer Richard Kearton says there is “no such dead level of unreasoning instinct” in the animal world as is popularly supposed, and he seems to base the remark upon the fact that he found certain of the cavities or holes in a hay-rick where sparrows roosted lined with feathers, while others were not lined. Such departures from a level line of habit as this are common enough among all creatures. Instinct is not something as rigid as cast iron; it does not invariably act like a machine, always the same. The animal is something alive, and is subject to the law of variation. Instinct may act more strongly in one kind than in another, just as reason may act more strongly in one man than in another, or as one animal may have greater speed or courage than another of the same species. It would be hard to find two live creatures, very far up in the scale, exactly alike. A thrush may use much mud in the construction of its nest, or it may use little or none at all; the oriole may weave strings into its nest, or it may use only dry grasses and horse-hairs; such cases only show variations in the action of instinct. But if an oriole should build a nest like a robin, or a robin build like a cliff swal­low, that would be a departure from instinct to take note of.

Some birds show a much higher degree of vari­ability than others; some species vary much in song, others in nesting and in feeding habits. I have never noticed much variation in the songs of robins, but in their nesting-habits they vary constantly. Thus one nest will be almost destitute of mud, while another will be composed almost mainly of mud; one will have a large mass of dry grass and weeds as its foundation, while the next one will have little or no foundation of the kind. The sites chosen vary still more, ranging from the ground all the way to the tops of trees. I have seen a robin’s nest built in the centre of a small box that held a clump of ferns, which stood by the roadside on the top of a low post near a house, and without cover or shield of any sort. The robin had welded her nest so completely to the soil in the box that the whole could be lifted by the rim of the nest. She had given a very pretty and unique effect to the nest by a border of fine dark rootlets skillfully woven together. The song sparrow shows a high degree of variability both in its song and in its nesting-habits, each bird having several songs of its own, while one may nest upon the ground and another in a low bush, or in the vines on the side of your house. The vesper sparrow, on the other hand, shows a much lower degree of variability, the individuals rarely differing in their songs, while all the nests I have ever found of this sparrow were in open grassy fields upon the ground. The chipping or social sparrow is usually very constant in its song and its nesting-habits, and yet one season a chippy built her nest in an old robin’s, nest in the vines on my porch. It was a very pretty instance of adaptation on the part of the little bird. Another chippy that I knew had an original song, one that resembled the sound of a small tin whistle. The bush spar­row, too, is pretty constant in choosing a bush in which to place its nest, yet I once found the nest of this sparrow upon the ground in an open field with suitable bushes within a few yards of it. The wood­peckers, the jays, the cuckoos, the pewees, the war­blers, and other wood birds show only a low degree of variability in song, feeding, and nesting habits.

The Baltimore oriole makes free use of strings in its nest-building, and the songs of different birds of this species vary greatly, while the orchard oriole makes no use of strings, so far as I have observed, and its song is always and everywhere the same. Hence we may say that the lives of some birds run much more in ruts than do those of others; they show less plasticity of instinct, and are perhaps for that reason less near the state of free intelligence.

Organic life in all its forms is flexible; instinct is flexible; the habits of all the animals change more or less with changed conditions, but the range of the fluctuations in the lives of the wild creatures is very limited, and is always determined by surrounding circumstances, and not by individual volition, as it so often is in the case of man. In a treeless country birds that sing on the perch elsewhere will sing on the wing. The black bear in the Southern States “holes up” for a much shorter period than in Can­ada or the Rockies. Why is the spruce grouse so stupid compared with most other species? Why is the Canada jay so tame and familiar about your camp in the northern woods or in the Rockies, and the other jays so wary? Such variations, of course, have their natural explanation, whatever it may be. In New Zealand there is a parrot, the kea, that once lived upon honey and fruit, but that now lives upon the sheep, tearing its way down to the kidney fat.

This is a wide departure in instinct, but it is not to be read as a development of reason in its place. It is a modified instinct, — the instinct for food seek­ing new sources of supply. Exactly how it came about would be interesting to know. Our oriole is an insectivorous bird, but in some localities it is very destructive in the August vineyards. It does not become a fruit-eater like the robin, but a juice-sucker; it punctures the grapes for their unfermented wine. Here, again, we have a case of modified and adaptive instinct. All animals are more or less adaptive, and avail themselves of new sources of food supply. When the southern savannas were planted with rice, the bobolinks soon found that this food suited them. A few years ago we had a great visitation in the Hudson River Valley of crossbills from the north. They lingered till the fruit of the peach orchards had set, when they discovered that here was a new source of food supply, and they became very destructive to the promised crop by deftly cutting out the embryo peaches. All such cases show how plastic and adaptive instinct is, at least in relation to food supplies. Let me again say that instinct is native, untaught intelligence, di­rected outward, but never inward as in man.

VII. THE ROBIN

Probably, with us, no other bird is so closely associated with country life as the robin; most of the time pleasantly, but for a brief season, during cherry time, unpleasantly. His life touches or min­gles with ours at many points — in the dooryard, in the garden, in the orchard, along the road, in the groves, in the woods. He is everywhere except in the depths of the primitive forests, and he is always very much at home. He does not hang tim­idly upon the skirts of our rural life, like, say, the thrasher or the chewink; he plunges in boldly and takes his chances, and his share, and often more than his share, of whatever is going. What vigor, what cheer, how persistent, how prolific, how adap­tive; pugnacious, but cheery, pilfering, but com­panionable!

When one first sees his ruddy breast upon the lawn in spring, or his pert form outlined against a patch of lingering snow in the brown fields, or hears his simple carol from the top of a leafless tree at sundown, what a vernal thrill it gives one! What a train of pleasant associations is quickened into life!

What pictures he makes upon the lawn! What attitudes he strikes! See him seize a worm and yank it from its burrow!

I recently observed a robin boring for grubs in a country dooryard. It is a common enough sight to witness one seize an angle-worm and drag it from its burrow in the turf, but I am not sure that I ever before saw one drill for grubs and bring the big white morsel to the surface. The robin I am speaking of had a nest of young in a maple near by, and she worked the neighborhood very industriously for food. She would run along over the short grass after the manner of robins, stopping every few feet, her form stiff and erect. Now and then she would suddenly bend her head toward the ground and bring eye or ear for a moment to bear intently upon it. Then she would spring to boring the turf vigorously with her bill, changing her attitude at each stroke, alert and watchful, throwing up the grass roots and little jets of soil, stabbing deeper and deeper, grow­ing every moment more and more excited, till finally a fat grub was seized and brought forth. Time after time, during several days, I saw her mine for grubs in this way and drag them forth. How did she know where to drill? The insect was in every case an inch below the surface. Did she hear it gnawing the roots of the grasses, or did she see a movement in the turf beneath which the grub was at work? I know not. I only know that she struck her game uner­ringly each time. Only twice did I see her make a few thrusts and then desist, as if she had been for the moment deceived.

How pugnacious the robin is! With what spunk and spirit he defends himself against his enemies! Every spring I see the robins mobbing the blue jays that go sneaking through the trees looking for eggs. The crow blackbirds nest in my evergreens, and there is perpetual war between them and the robins.

The blackbirds devour the robins’ eggs, and the robins never cease to utter their protest, often backing it up with blows. I saw two robins attack a young blackbird in the air, and they tweaked out his feathers at a lively rate.

One spring a pack of robins killed a cuckoo near me that they found robbing a nest. I did not witness the killing, but I have cross-questioned a number of people who did see it, and I am convinced of the fact. They set upon him when he was on the robin’s nest, and left him so bruised and helpless beneath it that he soon died. It was the first intimation I had ever had that the cuckoo devoured the eggs of other birds.

Two other well-authenticated cases have come to my knowledge of robins killing cuckoos (the black-billed) in May. The robin knows its enemies, and it is quite certain, I think, that the cuckoo is one of them.

What a hustler the robin is! No wonder he gets on in the world. He is early, he is handy, he is adap­tive, he is tenacious. Before the leaves are out in April the female begins her nest, concealing it as much as she can in a tree-crotch, or placing it under a shed or porch, or even under an overhanging bank upon the ground. One spring a robin built her nest upon the ladder that was hung up beneath the eaves of the wagon-shed. Having occasion to use the lad­der, we placed the nest on a box that stood beneath it. The robin was disturbed at first, but soon went on with her incubating in the new and more exposed position. The same spring one built her nest upon a beam in a half-finished fruit house, going out and in through the unshingled roof. One day, just as the eggs were hatched, we completed the roof, and kept up a hammering about the place till near night; the mother robin scolded a good deal, but she did not desert her young, and soon found her way in and out the door.

If a robin makes up her mind to build upon your porch, and you make up your mind that you do not want her there, there is likely to be considerable trouble on both sides before the matter is settled. The robin gets the start of you in the morning, and has her heap of dry grass and straws in place before the jealous broom is stirring, and she persists after you have cleaned out her rubbish half a dozen times. Before you have discouraged her, you may have to shunt her off of every plate or other “coign of van­tage” with boards or shingles. A strenuous bird indeed, and a hustler.

VIII. THE CROW

One very cold winter’s morning, after a fall of nearly two feet of snow, as I came out of my door three crows were perched in an apple tree but a few rods away. One of them uttered a peculiar caw as they saw me, but they did not fly away. It was not the usual high-keyed note of alarm. It may have meant “Look out!” yet it seemed to me like the ask­ing of alms: “Here we are, three hungry neighbors of yours; give us food.” So I brought out the en­trails and legs of a chicken, and placed them upon the snow. The crows very soon discovered what I had done, and with the usual suspicious movement of the closed wings which has the effect of emphasiz­ing the birds’ alertness, approached and devoured the food or carried it away. But there was not the least strife or dispute among them over the food. Indeed, each seemed ready to give precedence to the others. In fact, the crow is a courtly, fine-mannered bird. Birds of prey, will rend one another over their food; even buzzards will make some show of mauling one another with their wings; but I have yet to see any­thing of the kind with that gentle freebooter, the crow. Yet suspicion is his dominant trait. Anything that looks like design puts him on his guard. The simplest device in a cornfield usually suffices to keep him away. He suspects a trap. His wit is not deep, but it is quick, and ever on the alert.

One of our natural history romancers makes the crows flock in June. But the truth is, they do not flock till September. Through the summer the dif­ferent families keep pretty well together. You may see the old ones with their young foraging about the fields, the young often being fed by their par­ents.

From my boyhood I have seen the yearly meet­ing of the crows in September or October, on a high grassy hill or a wooded ridge. Apparently, all the crows from a large area assemble at these times; you may see them coming, singly or in loose bands, from all directions to the rendezvous, till there are hundreds of them together. They make black an acre or two of ground. At intervals they all rise in the air, and wheel about, all cawing at once. Then to the ground again, or to the tree-tops, as the case may be; then, rising again, they send forth the voice of the multitude. What does it all mean? I notice that this rally is always preliminary to their going into winter quarters. It would be interesting to know just the nature of the communication that takes place between them. Not long afterwards, or early in October, they may be seen morning and evening going to and from their rookeries. The matter seems to be settled in these September gatherings of the clan. was the spot agreed upon beforehand and notice served upon all the members of the tribe? Our “school-of-the-woods” professors would probably infer something of the kind. I sus­pect it is all brought about as naturally as any other aggregation of animals. A few crows meet on the hill; they attract others and still others. The rising of a body of them in the air, the circling and caw­ing, may be an instinctive act to advertise the meet­ing to all the crows within sight or hearing. At any rate, it has this effect, and they come hurrying from all points.

What their various calls mean, who shall tell? That lusty caw-aw, caw-aw that one hears in spring and summer, like the voice of authority or com­mand, what does it mean? I never could find out. It is doubtless from the male. A crow will utter it while sitting alone on the fence in the pasture, as well as when flying through the air. The crow’s cry of alarm is easily distinguished; all the other birds and wild creatures know it, and the hunter who is stalking his game is apt to swear when he hears it. I have heard two crows in the spring, seated on a limb close together, give utterance to many curi­ous, guttural, gurgling, ventriloquial sounds. What were they saying? It was probably some form of the language of love.

I venture to say that no one has ever yet heard the crow utter a complaining or a disconsolate note. He is always cheery, he is always self-possessed, he is a great success. Nothing in Bermuda made me feel so much at home as a flock of half a dozen of our crows which I saw and heard there. At one time they were very numerous on the island, but they have been persecuted till only a remnant of the tribe remains.
