It is an interesting fact that about all the work of domestication which has been done by man has been accomplished by the peoples of Asia and mainly by the Aryan race. The American Indians tamed the llama and alpaca and a few species of native plants; even where their habits were prevailingly sedentary they domesticated no birds. It was left for Europeans to make use of the wild turkey. Our primitive people had the same chance to tame ducks and geese as the folk of the Old World. They appear, however, to have lacked all capacity for such endeavors. The same lack of disposition to capture and tame wild creatures is noticeable among the characteristic peoples of Africa; all of which serves to show that the domesticating art, at least as applied to animals, is peculiar to the higher-grade folk of the Old World.

Of all the birds which have been domesticated, our common barnyard fowl has been by far the most useful to man. It has become in a way interwoven with his life to a degree found only in a few of our barnyard animals. Next after the pigeons and the pigs it has been most deeply impressed by the breeder's art. The wild species whence it sprang is a small creature, laying but few eggs and with but a slight tendency to accumulate fat. From this parent stock varieties have been bred which attain in some cases to eight or ten times the weight of the ancient form. They have, moreover, lost the fierce combative spirit which characterizes their ancestors and which by selection has been preserved and intensified in our breeds of game-cocks.

Various types of fowl.

The Original Jungle Fowl (Gallus bankiva)
and Some of His Domestic Descendants

It is an interesting fact that our barnyard fowl is the only species of a large family of birds which has been truly domesticated. The kindred pheasants and grouse, though abounding in the Old World and the New, and much disposed to abide about the cultivated fields, appear to be rather untamable. However well cared for, the wilderness motive seems never to have been eradicated. The domesticability of the cock, as is that of most other wild animals, is doubtless to be explained by the conditions of the life in which it has dwelt for ages before it was introduced to the society of man. In its wild state this bird had already to a great extent lost the power of flight, using its wings only for escaping from four-footed pursuers or to attain the branches of the trees in which it sought safety in the night time. With this measure of loss of the flying power, the creature abandoned the habit of ranging over a wide field, and thus was made more fit for domestication. Moreover, in their wilderness life these birds dwelt in more established communities than their kindred species. The most of these wild forms do not keep together through the year, but scatter after the young are able to shift for themselves. The Indian species of Gallus, however, from which our cocks and hens descend, have organized their life so that the individuals remain associate in a friendly way throughout the year.

A part of the fitness of this creature to cast in its lot with man arises from the fact that they have very sympathetic natures. This is shown by the way in which the cocks will fight for their hens, even against their dreaded enemies, the hawks; and by the manner in which the mother, overcoming her natural fears, will do battle for her brood. It is shown also in the curious mingling of gallantry and kindliness with which the cock will call a hen to give her some choice bit of food which he has captured. As he grows older and becomes Philistinish, we may note that, after the manner of unfeathered bipeds, he is often disposed to indulge his selfishness, and summons his flock only to see him devour the morsel. Even in old age, however, the males of the varieties which are nearest the parent stock maintain their helpful motives and will struggle with infirmity to beat off a bird of prey.

The sympathetic and affectionate quality of our barnyard fowl is perhaps best indicated by the singular variety and denotative value of their various calls and cries. Those who know these birds well will find no difficulty in recognizing about a score of diverse sounds, each of which indicates a particular turn of their mind. Almost all of these different notes have slight variations of expression which fit particular situations. Thus the crow of these birds, which may seem to the unobservant a very unvaried sound, discloses to those who have lovingly studied them at least half a dozen distinct modifications. In the fledgling male who just begins to feel the spirit of his kind, and who goes through his performance in the adolescent way, it is a cheap and often pitiful call. From the open roost in the trees, where the birds are gradually aroused by the slow-coming day, we can often hear the note of the half-awakened cock, as full of the sense of slumber as the speech of a sleeping man. As the creature gradually awakens, his cry becomes more resonant until it has the true morning ring. Brave as is this note of the full day, it is not to be compared with the crowing of a game-cock, the most splendid braggart sound of all the animal world.

The really sympathetic notes of our fowls are uttered in their ordinary intercourse. Here the gradations of sounds have a range and fineness which, it seems to me, we can observe in no other creature below the level of man. Attention, astonishment, fear, commonplace distress, exultation, and agony are all set forth with cries which we, in a way, recognize as appropriate. Although some of these sounds relate to the larger experiences of the creatures, the most instructive of them are uttered in their ordinary intercourse, where they clearly maintain a kind of consensus in the flock by unending small bits of emotional speech, the notes being shaded in a wonderful way. These fine variations of utterance can sometimes be observed to be related to slight differences of situation. Thus the cackle of a hen when she leaves her nest after laying an egg is quite different from that which is made by the same hen when, during the period of incubation, she quits her eggs in search of food and water.

It is not unlikely that the eminent domesticability of our common fowls is in a way associated with the singular variety of their notes. This variety indicates that the creatures are in constant and effective communication with one another; in a word, they are very sympathetic. With this intellectual helpfulness naturally goes the love of the domicile and a disposition to submit to control.

So nice and well understood are the differences between the sounds which these birds give forth, and so well are their notes appreciated by their companions, that the creatures may well be said to have a language. Though it probably conveys only emotions and not distinct thoughts, it still must be regarded as a certain kind of speech. The modes of expression indicate that in this creature, as in the other feathered forms, the intellectual life consists largely in the movements inspired by the emotions. On the rational side our fowls seem weaker than many other less interesting species. In their nesting and other habits there are no evidences of constructive ingenuity; and in all my observations on them I have never seen any evidence which showed either considerable powers of memory or a capacity to act in any complicated way with reference to an end. It is evident, however, that they make a very good classification of the world about them. They have, for the limited field over which they roam, a keen topographic sense; they never are lost, and this in connection with their sympathetic homing instinct prevents them from wandering from their accustomed places to take up again with a wilderness life.

In their adhesion to domestication our common fowls differ in a remarkable way from all other of our captive animals except the dog, and these birds are even more ineradicably attached to man than their older companion. While the dog will sometimes become half wild, or, as we may phrase it, undomiciled, fowls seem incapable of maintaining themselves apart from human care. In much ranging of the wilderness I have never found one of these creatures more than a thousand feet away from a human habitation. When we consider how common must be the chances of their going astray, and how easy it is in many parts of the country, as in our Southern States, for them to obtain in the wilderness food throughout the year, the fact that they never go wild is indeed remarkable. It can only be explained by the great development of the homing instinct which man has brought about in their sympathetic souls.

Although our unnatural process of breeding has done much to degrade the original beauty of the cocks and hens, destroying the delicate coloration of the feathers as well as the admirable blending and contrasts of their pristine hues, it seems likely that the effect on the physical and mental development as a whole has not been unfavorable. Though less courageous, they are stronger creatures than in their wild state; they are clearly more fecund; they are gentler natured; and, so far as I have been able to compare the high-bred with the primitive forms, their range of expression through the voice has been much increased, a feature which may be noted in other domesticated species of birds, as, for instance, in the canaries. The most remarkable alteration which has been brought about in the minds of these creatures consists in the very great diminution in the combative motive of the males. In the wild forms, as well as in the kindred variety of the game-cock, this impulse to battle attains a truly phenomenal development, the like of which is probably not to be found in any other creature. The male birds begin their warfare before they are more than half grown, and in their adult state will attack anything which they can conceive to be an enemy. They will, with slight provocation, assail any of the other domesticated species of birds, and even the lesser mammals, such as the dogs and cats. They will fight their own image in a looking-glass. I have had game-cocks attack my hand when it was held near the ground and given an up-and-down movement in imitation of their antagonist's head.

I once reared a game-cock by hand, keeping him secluded from his kind until he was adult. I then placed him in a large collection of barnyard fowl where there were half a dozen mongrel cocks, a drake of the muscovy variety, several ganders, and two turkey-gobblers. Immediately and in rapid succession he settled his accounts with the males of his own kind. He shortly overcame the drake and the ganders. He then devoted what was left of his forces to battles with the turkeys. Here he found himself in great difficulty, for the reason that these great birds would seize him by the head and lift his body off the ground. However, he soon learned an ingenious trick which protected him from this danger. When gathering breath in the intervals between his assaults, he would hover himself between his antagonist's legs, keeping step with the awkward creature in its efforts to get away from him. In a few days he wore out these doughty foemen and remained the battered master of the field.

Although the indomitable valor of the game-cock may be in some measure due to the selection which the breeder has applied to the variety, there can be no question that it is essentially natural to the species and is the result of an age-long habit which in the native wilds of the creature did much to insure its safety. The antiquity of the state of mind may be judged by the perfection to which the spurs have attained and the remarkably skilful and definite way in which the creatures use them. The spur, which has arisen from the development of the scales and underlying bone of the bird's leg, is a singularly perfect structure, the finish of which cannot be judged in the degraded form in which it is found in our ordinary barnyard species. Although in its construction this weapon is admirably devised, it is placed in a position where only a remarkably well-addressed movement can give effect to its blow. Those who have watched game-cocks in combat have had a chance to see the vaults by which the creature, partly turning in the air, is able to throw the spur in such a manner that it shares the impulse of the body when it strikes the antagonist. This peculiar craft has been in good part lost among our common varieties. Their spiritless contests differ as much from those of the game-birds as do the fist fights of untrained men from the contests of skilled pugilists.

Although to persons unaccustomed to the spectacle the combats between game-birds may seem disgusting, almost every one must admire the valor, grace, and address which such scenes exhibit. Except where the brutal custom of putting steel points on the spurs prevails, the birds rarely receive fatal wounds. The defeated cock is soon brought to confess his inferiority and takes himself away. At no other time in the life of these birds does their organic beauty appear to such advantage as when they are struggling with each other. Then alone do we perceive the singular efficiency of their bodies and the quick as well as appropriate action of their instincts. They set themselves against each other in attitudes as well chosen and as peculiar as those of a well-trained fencer. Before the assault they often go through a singular performance, which consists in picking up bits of twigs or pebbles. These they cast into the air, an unmeaning movement which may be compared to the like meaningless though similarly graceful salute with which swordsmen preface their contests. Then, with their legs flexed so that they may be ready for the spring, and with the rather stiff feathers about the neck erected so as to serve as a shield, they creep toward each other until they are separated by the distance appropriate for the spring. When fairly placed for battle they begin a system of fence which is intended to provoke the enemy to an untimely assault. The art of the game appears to consist in persuading the adversary to venture an attack where his force will be spent in the air, so that a blow can be given him before he has time to recover position. The issue depends much on the endurance of the birds. Their movements require so much energy that one of them is apt to become exhausted before the other is quite spent. In rare cases, only one of which has been seen by me, a weary bird will feign death for a minute or so and thus obtain new strength with which to renew the combat, profiting also by the confusion which he will bring upon his adversary by his sudden revival.

Although the combatant motive which we find in the males among our barnyard fowls has doubtless been developed through their combats with each other, the valiant spirit which has come from it often leads the creatures to attack the enemies of their flock. I have seen a nimble game-cock strike a hawk which was pouncing to its prey, delivering the blow some feet above the surface of the ground, and this so effectively that the marauder was driven away in a sorely hurt condition. I have seen males of the game variety attack a number of other larger animals which in any way threatened their charges.

Although our barnyard fowl are almost the only ground birds which have ever been brought to a state of perfect domestication, there are several other species of the same group which have been taught in a measure to adhere to man. Of these perhaps the longest in domestication is the peafowl. This creature, though it has edible, indeed we may say savory flesh, has retained its small place in civilization solely on account of its extraordinary beauty. For its size it is doubtless the most beautiful of animals, its plumage, especially the magnificent display of the tail, exceeding that of any other natural object. There are other birds of small size which vie with the peacock in the details of ornamentation. Those jewels among the feathered tribes, the humming-birds, have a more delicate beauty. The birds-of-paradise and the lyre-birds have a grace in the attitudes of particular feathers which is unequalled; but for splendor none of them approach the peacock in his best estate.

Contributions from Asia, Africa, and America—Peacocks, Guinea-fowl, and Turkey

The peacock is a native of Southern Asia, a realm in fact in which the species of the group attain an uncommonly rich development. The creature appears to have been domesticated some thousands of years ago, but has undergone no considerable changes in its experience with man. It has in truth not been completely tamed. It does not willingly remain near the dwellings of man, but prefers to abide apart, only resorting to the home when in need of food. It is very intolerant of the other barnyard creatures, and often becomes possessed of a kind of mania for slaying their young, not for food but from pure spirit of mischief.

Intellectually speaking, the peacocks are much below the cocks and hens; although they flock together, their sympathies do not seem quick; their cries and calls do not number a fifth part of those which we hear from our chickens, and their notes are prevailingly very discordant. Their cry of defiance, answering to the crow of the cock, is one of the rudest and least sympathetic sounds which is heard among the birds. Its only merit is that it can be heard very far. It is readily audible at the distance of a mile when it breaks the stillness of a summer night. At present the bird seems out of favor. At best it is a beautiful but annoying ornament to pleasure-grounds. It is likely, indeed, that it may in time become limited to its native wildernesses and to zoÖlogical gardens.

From Africa we have derived one rather uncommon tenant of our barnyards and fields, the guinea-hen. This creature, though of convenient size, hardy, and commendable from the number of eggs it lays, has never won a large place in the esteem of our rural people, and is now not much kept, except in some parts of the Southern States of this country. The difficulty with this creature, as with the peacock, is that it is not truly domesticated; though it will not betake itself altogether to the woods, it prefers to maintain a half-wild habit. It will not, if it can possibly avoid it, lay its eggs in any place where they are likely to be found by man. Moreover, their rude and little-modulated cries are in the summer season almost incessant, and the din which a considerable flock can produce is exceedingly vexatious. They thus do not fit the needs or comfort of man to the degree which is likely to give them a permanent place among his associates.

The last considerable addition to our barnyards has come to us in the form of the turkey. This species has the peculiar distinction of being the only animal form of definite use to man over a wide field which has been contributed from the life of the New World. Although the creature was much hunted by our North American Indians, and is of a type which lends itself to domestication, it does not appear to have become a companion of man until it was taken from the West India Islands to Europe shortly after the discovery of this country. Thence the domesticated form appears to have been returned to this country, where it has been a favorite in a measure unknown in the Old World. Ornithologists deem the Cuban turkey, whence our tame form came, to be specifically distinct from those which are found on the mainland of this continent. Although these kinds are distinguishable by plumage, they are probably only varieties of a common species. This is indicated by the fact that our tame flocks readily intermingle with their wild kindred.

The ease with which the turkey becomes domesticated is remarkable. In this regard the creature may be compared to our cocks and hens. In both cases the tamableness is doubtless to be explained by the fact that the primitive forms dwelt in permanent association, the movements of which were in a way controlled by the adult males, and by the fact that the forms had abandoned the use of wings for wide-ranging flight. The change which has been brought about in the turkeys with their adoption into the human association has been slight. No distinct varieties of breeds have been originated, though here and there the observer may note slight local variations in the coloration of the plumage, which are probably due to varying admixtures with the wild forms of our forests. Thus in Kentucky and other parts of the South, where the opportunities for the intermingling of blood of the tame and wild forms are frequent, the domesticated creatures often resemble so nearly the wilderness forms that even the wary hunter may make mistakes as to whether the bird he sights be fair game or not. Unless carefully watched, a drove of these creatures on the border of the wilderness is apt gradually to return to the wild state, the three or four centuries of life about the home of man not having been sufficient to do away with their ancient love of freedom.

Among the English folk of North America the turkeys found a large place as an element of the food-supply. It has become curiously associated with the Puritan festival of Thanksgiving, an institution which has spread throughout the United States and which has in a way taken the place of the harvest-home festivities of the Old World and bygone ages. It is probable that the relation of this bird to our national festivities has done much to keep it in use in this country. It is a well-recognized fact that it is costly to keep and that the eggs are not desirable for culinary use. The species requires a wide range. It does not do well in the confined conditions in which cocks and hens can readily be maintained. It therefore is not likely to be kept in any region where the agriculture is of a high grade. It is best suited to farms where there are considerable areas of half-wild pastures.

Although the turkey is a truly gregarious form, its mental endowments are of a lower grade than those of most social birds. Their calls are few in number and have little of that conversational quality which we note in those of our ordinary barnyard fowls. Although the males contest the field with each other by personal combats, they are not very valiant, the creatures trusting for favor with the females rather to the parade of their plumage and the pomp of their carriage than to the wager of battle. In the matter of show they are, however, very effective, being surpassed only by the peacock in the splendor of their attire. In their domesticated state they lose much of the beauty which they have in the wilderness, as they do their pristine dimensions. Those who have hunted our wild species are likely to remember scenes where in some forest glade they have beheld a gobbler displaying his graces to an admiring harem. As he struts about with his tail feathers erect and his neck arched back, now and then pausing to utter an exultant gobble, the spectacle is one of the most amusing displays of animal pride which the naturalist has a chance to behold.

Recent experiments in ostrich farming seem to indicate that we are on the eve of introducing into our "happy family" the noblest remaining member of that group of great birds which characterized the life of the later geological periods. As yet the efforts in taming ostriches are too new for us to tell just what the effect of man's skill on the development of this creature will be. It is evident, however, that the creature can be won from its wilderness state, at least to something like the imperfect companionship with man which has been attained by the guinea-fowls and turkeys. All we know of the variations in plumage of birds indicates that the breeder's art may bring about great changes in the highly decorative feathers for which this bird is to be reared. It is also probable that with the better food which domestic conditions imply, this wanderer of the desert may be brought to attain a very much greater size than it wins in the hard life of its native land. If the form should prove as plastic as that of our ordinary barnyard species, we may indeed succeed in developing a variety approaching in dimensions the gigantic moa of New Zealand, or the Æpyornis of Madagascar, those magnificent creatures of the past which passed away just before their native lands were known to our race. The variations in size of the wild ostrich appear to indicate that this interesting result may be attainable.

Next after the cocks and hens the most important birds of economic value have come from the water fowl. In this field there are great opportunities for domestication, only a few of which have been adequately used. The aquatic birds, save for the fact that they are in all cases inspired with a more or less strong migratory humor, lend themselves to the shaping hand of man more readily than most other forms. These creatures have the habit of association in a much more perfect way than our ground birds. They normally dwelt in rather close order and in relations which are necessarily very sympathetic. Whoever has watched the flight of wild geese must have remarked the beautiful way in which they arrange at once for close companionship and for safety in the violent movements which impel their heavy bodies at high speed through the air. In the order of their flight the alignment is more perfect than in the march of trained soldiers. Each bird keeps as near to his neighbor as possible; but manages always to preserve the interval which will insure against a collision of the strong and swift-moving wings, an accident which might well disable them for flight. I have repeatedly undertaken to confound their motion by firing a rifle bullet at the head of the moving wedge. Although the sound of the projectile, if well directed, will disturb their processional order, it never brings confusion. The startled birds sink down or rise above the plane of the air in which their comrades are moving, but they never strike against them.

The admirable sense of interval which the wild birds exhibit in their flight is to be seen also when they move over the surface of the water, where the fleet of living forms is always so arranged that each individual does not interfere with its neighbor. I recall with much pleasure an occasion when, from a ship becalmed in a thick fog off the southern shore of Labrador, within sound of the breakers, I undertook to find something about the lay of the land and the chance of harborage by paddling in a small boat toward the shore. I had hardly lost sight of the ship when my boat glided into an assemblage of eider ducks, where the mothers, with their fledgling young, were lazily swimming to and fro, as if to practise the ducklings in the art of swimming. Each brood appeared to have its own space of water, and between each of the chicks there was likewise a less but equally well measured interval. The same features of orderly association, which I have just noted in the swimming and flying of these wild birds, may be seen in a somewhat degraded state in our domesticated varieties of the group. They all indicate in these forms a keen sense of their neighbors and a habit of association based upon sympathetic emotions.

The sympathetic quality of our water fowl, at least in that part of the emotion which leads them to be concerned with the afflictions of their species, appears to be more distinct than in the case of our ordinary barnyard fowl. Geese, as is well known, will make common cause against an intruder from whom harm to the flock may be expected. Their simultaneous din when anything occurs to arouse their enmity is commemorated in the ancient myth concerning the aid which they gave in the defence of the walls of Rome. There are anecdotes apparently well attested where water fowl have borne away a wounded comrade which had fallen before the huntsman's fowling-piece. In Smiles's "Life of Edwards" there is an often-quoted story which appears to be trustworthy and sufficiently illustrates this point. A hunter, having shot one of a flock of terns, which fell wounded into the water near the shore, waded in to seize it. Suddenly two of the terns came to their wounded companion, seized him by either wing, and bore him toward the open sea. When these two helpers were weary, the sufferer was lowered into the water, and, in turn, seized by two other birds which were fresh for the labor. Working in succession, these birds carried their companion to a rock some distance from the shore. When the hunter endeavored to approach the rock, yet others of the species seized the cripple and bore him far beyond reach.

Although too much value must not be given to the numerous anecdotes concerning the sagacity of water fowl, the great mass of these stories, as compared with the poverty of the anecdotes concerning the better-known barnyard creatures, seems to establish the fact that their intelligence is much greater than that of the land birds. This superiority can probably be attributed to the fact that their life requires much more definite adaptation of means to ends than in the simpler conditions which are met by the forms which dwell in the fields. The circumstances of their life are something like those of the seals among mammals. They have to do with the conditions of the air, the land, and the water; and as they generally undertake long migrations, the range of the things they have to accommodate themselves to is great, and the effect of their labor is decidedly educative.

As yet, from the great number of species of water fowl man has really domesticated but two characteristic groups, the species of geese and of ducks. Swans have been brought to a state where they tolerate the presence of man, though they rarely establish any really intimate relations with him. Some other species, as, for instance, the grebe, have been taught to dwell about the homes of man, accepting food from his hands. It is likely that more of these water fowl would have come into human associations were it not for the fact that they are naturally migratory, and when, after a season of domestication, they join a passing flock, they never return to the place where they have been kept.

The swan, like the peacock, has been bred for ornament rather than for use. In fact, the bird has no other merit than its exceeding grace. We cannot believe that much pains was ever taken with this creature to break up the migratory instincts which are common in the wild kindred species. We have to suppose that the bird in its pristine form was without the impulse to undertake distant journeys in the winter season, or that it abandoned ancient habits with no great difficulty. We obtain some light on this point by noting the fact that among the migratory species it not infrequently happens that, while the greater number of individuals undertake the annual journey, certain of them will remain on the ground where they were born. Those which remain would be more likely to mate with those which were like-minded than with others that journeyed afar. In this way small local breeds might well be originated which would differ from their migratory kindred not only in the measure of the wandering instincts, but in the capacity for flight which their kindred preserve. There is some reason to believe that this process of selection naturally and somewhat frequently takes place. In certain cases it may lay the foundation of new species, or at least of distinct varieties; more commonly, however, the individuals which have abandoned the migratory life are likely to perish from the severity of climate or the other unfavorable conditions that their mates avoid by their wanderings.

Although many of the free-flying birds of the land are or have been kept captive because of the pleasure which men have found from their songs, their grace, or their quaint ways, only one of these has really been gained to domestication. In the pigeon, man has made what is on many accounts the most remarkable of all his conquests over the wild nature about him. While the breeder's art has led many forms, some of them on several divergent lines, far away from their primitive estate, in no other field has it accomplished such surprising results as with the doves. The original wild form of this group is a native of Europe and Asia, where the species Columba livia, or rock pigeon, is still common, and whence it may be readily won anew to domestication. It is a small, plain-colored, rather invariable and inconspicuous bird about the size of our American dove. In its wild state it dwells in small flocks, nesting by preference in the crannies of the cliffs, and exhibiting no striking qualities which make it seem a desirable subject for domestication. We note, however, that even in this primitive condition the creature has certain physical and mental qualities which have been the basis of its adoption by man as well as of the wide changes which it has undergone at his hands.

It is a characteristic of all the doves that their young are born in a very immature state, and for some time after they come from the egg they have to be supplied with food which has been partly digested in the crop or upper part of the stomach of the parent. For the proper rearing of the brood there is required the assiduous care of both parents. Therefore quite naturally we find among these birds that the pairing habit is well developed, and as they rear several broods each season, that the mating is for life. Although there are numbers of birds in various orders which are accustomed to the monogamic habit, it happens that the pigeon is the only animal which man has ever won to true domestication in which the sexes can be thus permanently united. In the dovecote, however many birds it may contain, the breeder can be always sure as to the parentage of the young which he is rearing. This affords an admirable basis for the practice of his art, which is still further favored by the fact that pigeons reproduce rapidly and the progeny are ready to mate in a few months after they come into the world. Thus the species affords really ideal conditions for that process of selection on which the improvement of all domesticated animals intimately depends.

Selective breeding of pigeons began in India, as the records seem to show, more than two thousand years ago. Though other animals have been brought to domestication at much earlier times, this appears to have been the first of them to be subjected to deliberate efforts on the part of their masters, which were intended to bring about in a methodical way certain changes in their forms and habits. The most curious part of this great endeavor which has been applied to breeding pigeons is found in the fact that the ends sought have no utility, but afford satisfaction from the point of view of pure diversion or the gratification of taste. We are well accustomed to the action of such motives upon our flowering plants of the garden, but the pigeon is the only animal where fancy has labored for thousands of years for its gratification. The breeders of pigeons from remote antiquity to the present day appear to have had no definite purpose in all their pains. They have taken the chance variations in form and habit and endeavored to extend these sports of nature by a careful system of mating those in which the singular features were most evident. Thus the fan-tail breed has been developed until the creatures display their unornamental tail feathers with all the dignity with which a peacock shows his marvellous decorations. The pouters have in some unaccountable way learned to take air into their crop; and the habit has been developed by selection until the bird destroys all trace of his original shapeliness, though he seems to take pride in his diseased appearance. The tumbler, probably derived from some ancestor afflicted with a disease of an epileptic character, manages to go through his convulsions in the air without serious consequences and apparently with some pleasure to himself. There are over one hundred less conspicuous varieties, of which only one deserves notice, and this for the reason that it has some possible utility to man and is now much attended to. This is known as the carrier pigeon.

In early time, before the invention of the railway and telegraph, some ingenious breeder of pigeons, observing the constant way in which these creatures returned to the place where they were bred, invented the plan of using them to convey information. This service was found convenient not only for ordinary correspondence, but was exceedingly valuable where a place was beleaguered by an enemy. In such cases carrier pigeons could often be used to convey information across the otherwise impassable lines. Even in modern times, as, for instance, during the last siege of Paris, these swift and sure flying birds proved of great use in keeping up communications between the people of the invested town and the French armies in the field. Letters in cipher, sometimes photographed down until the characters were microscopically fine, were made into packages of small weight in order not to impede the flight of the bird, carefully affixed to its body, and thus sent away. Very generally these curious shipments came to the hands of those for whom they were destined. The birds can be trusted to fly at night; they retain for a long time the memory of their home, and spare no pains to return to it.

The homing power of the carrier pigeon appears to be a special development of a natural capacity, as is also its swiftness and endurance in flight. Our other breeds and the wild species whence they have all come are not disposed to undertake long journeys; they rarely, indeed, wander far from their abiding places. Our experience with the carriers shows how readily the creatures may be educated to perform feats which they were not accustomed to do in their wild state. Something of the same elasticity of constitution may be observed in the bodies of our pigeons as they have been affected by selection. Not only has the plumage been greatly altered by the breeder's art and in pursuance of his plans, but the form and proportions of the bones have coincidently and unintentionally been greatly changed. So considerable are these alterations that if these creatures were submitted for dissection to a naturalist who knew nothing of the history of the bird, he would have no hesitation in classing them as belonging not only in different species, but as members of diverse genera.

It must be regarded as unfortunate that the experiments which have been made on pigeons have been limited to their features of form, color, and slight peculiarities in their habits. If the breeders had sought to modify the intellectual parts with anything like the insistence which they have given to the development of these bodily peculiarities, we might now have a most valuable store of knowledge as to the limitations of animal minds. The facts gained in the breeding of the carriers show clearly that certain of the instincts of these birds can be readily modified. There is every reason to suppose that their mental capacities in other directions have something of the same pliability.

Although the pigeon is the only free-flying form which has been won to intimate relations with man, there are numerous other species of these volant creatures which have been reduced to partial domestication, though they cannot be trusted to abide with us without being more or less completely caged. Experience has shown that by far the greater part of the arboreal birds may be kept and will breed in captivity. From the host of these feathered creatures men have from time to time selected species which grace their habitations by their beauty, their song, or by the sympathetic relations which they form with their captors. Our successes in these efforts toward domestication of these birds have been most eminent with those varieties which in their wilderness state have a well-developed social life, which abide in families or flocks, and have the pairing habit well affirmed. The reason for this has been already indicated. It is due to the sympathetic motive which is developed in such communal life, and is manifested in the friendly relations with each other which the creatures maintain. A good instance of this is to be found in the crows and their kindred, a group of extremely sociable creatures, which are endlessly engaged in chattering communications with each other. All these forms are highly domesticable, and if for any reason they had proved permanently attractive to men they would doubtless have been brought into the state of willing captives.

Although some of the free-flying or tree birds have been kept for their beauty alone, the greater part of them have commended themselves to man because of their voices. It is hardly necessary to tell the reader that the birds, of all animals, are most provided with means of expression through the voice. There is hardly a species which has not a greater range of notes or calls than the most vocal of our wild mammals, and many varieties are impelled to tuneful expression in a measure which no other creature, not even man, exhibits. In most cases these utterances are pleasing to the human ear, for they have the quality which we term musical. Therefore it is not surprising that the most of our captive birds have been chosen for their song.

It seems clear that the song of birds, like their calls—the two shade indefinitely into each other—expresses a sympathetic emotional consciousness of the actions going on about them, particularly of the life of their kind. In general these utterances are directed toward their kindred of their own species. In many cases, however, as among the imitative birds, the sounds which they utter indicate a curiously keen interest in the actions of their masters or other human affairs. The mocking-birds and some other species will, with great assiduity, endeavor to copy any sound which they happen to hear. I well remember watching a mocking-bird which was listening with rapt attention to the noise produced by a man sharpening a saw with a file. The poor bird would hearken with great attention until he thought he had caught the note, and then endeavor to reproduce it. As may be imagined, the measure of his success was small. He was fully conscious of his failure, and would beat himself about the cage in evident chagrin, returning again and again to try the hopeless task.

Wherever the vocal organs of caged birds permit them to imitate human speech they are apt to devote a large part of their labor to this task, paying little attention to other less meaningful sounds. It appears to me that they perceive in a way the sympathetic character of language and therefore take a peculiar pleasure in copying it. It is hardly to be believed that they ever get a sense of the connotative value of words, but it is not to be doubted that they sometimes attain to a certain appreciation of the denotation of simpler phrases. In this task they do not exhibit as much sagacity as the dog, a creature which learns to understand the purport of rather complicated sentences. Nevertheless, their capacity for imitating speech is a fascinating peculiarity, one which has greatly endeared them to bird fanciers.

Those who have observed the talking birds have doubtless noted the fact that their capacity for remembering and uttering words varies greatly. I am inclined to think that in the same species some individuals can do such tasks several times as easily as others. If these speaking forms could be brought to breed in captivity, and something like the selective care were given to their development that has been devoted to the varieties of pigeons, we might well expect to attain very remarkable results. If anywhere in the animal world there is a chance to open communication by means of speech with the lower creatures, it should be here.

At one time among our ancestors it was accustomed to make much use of the larger hawks in hunting. Curiously enough this amusement, more refined and elaborated than any other form of the chase, has gradually fallen into disuse among Europeans. So far as I have been able to learn, the only region in which it is well preserved is in northern Africa, a country in which the custom was probably introduced from Spain during the occupancy of that peninsula by the Moors. From the literature of this art of hawking, even after we allow much for the exaggeration of unobservant men, it seems certain that the training of these fierce birds was carried to a point of singular perfection. The creatures learned to do their duty in a very skilful way, and they readily acquired habits of obedience, under circumstances of excitement, more perfect than those which we succeed in instilling in any animal but the dog. When we consider the natural qualities of the hawk, and note that when well trained he flew at only the designated game, and came back to the master when a bit of hide or other lure was thrown into the air as a signal, we may fairly believe that the creature displayed an extraordinary fitness for receiving instruction. The facts are the more remarkable because these hawks were not bred in cages, but were taken from the wild nests; so that there was none of that gradual accumulation of inheritances under the conditions of selection which have brought about the obedience of our really domesticated animals.

The remarkable way in which the art of hawking has disappeared from our civilization deserves more than a passing notice, though it appears to be inexplicable. It is evident that it was a tolerably ingrained habit, at least among the English-speaking people, for it has left a very deep impress upon the language. There are far more phrases derived from the custom than can be traced to any other of the sportsman's arts. At least one of these collocations of words which has escaped from the minds of grown people still holds a place among the boys of this country. When two lads are fighting we often hear the bystanders say, by the way of encouragement to one of the contestants, "Give him jesse." The use of this curious phrase prevails in all parts of the United States, but after much inquiry I have failed to find a trace of it preserved in England. There seems to be little doubt that these words are due to a custom of beating a hawk which failed to do its duty with the thongs or jesses by which it was attached to the wrist of the falconer. Giving another jesse thus came to be equivalent to giving a person a strapping.

Whatever may have been the reason for abandoning this beautiful and in a way noble sport, its disuse must be deemed most unfortunate by all the students of animal intelligence, for it has deprived us of precious opportunities in the way of observations on the mental peculiarities which exist in a most interesting group of birds. In these days, when there is a fancy for reviving the customs of our forefathers, it might be well for some persons of leisure to give their attention to restoring the arts of falconry. Enough of the practice and of the traditions is left to make it an easy task to reinstitute all the important parts of the custom. Moreover, those who essayed the matter would have access to a much greater range of rapacious birds than our forefathers, who had to content themselves with the limited number of wild species which inhabit the continent of Europe. Especially on our Western plains, where game-birds abound and the country lies wide open, sportsmen would find an admirable field in which to follow the bird they flew. Not only would the restoration of hawking give us a sport much more skilful and refined than the fox chase, but it would reintroduce the cultivation of the only creature which, having once been brought to the service of man, has been permitted to return to its ancestral wild life.

The most striking and by far the most interesting quality exhibited by our birds is found in their sympathetic motive. In this spiritual quality, so far as it relates to their own kind, the feathered creatures are clearly in advance of all other species, including even man. A single fact, one of great generality, will serve to make this statement clear. Among the birds we find the only cases of true marriage which are known in the animal kingdom. In the greater number of the species the union is for a season, but among many it is for life. In the case of certain varieties of paroquets, the union is so indissoluble that, according to common report, a report which seems much better verified than the most of those concerning the habits of animals, neither member of the pair will survive the death of the other. Man, with all his striving towards a better social state, has, as a whole, not yet attained to the enduring affection for the mate which is evinced by the greater part of the birds.

In this same connection, we may note that the Æsthetic appreciation among the birds appears to have attained a far higher level than it has won in any other creatures. There can be little doubt that the exquisitely beautiful plumage, the unparalleled shapeliness of form and grace of carriage, as well as the melodies which are uttered by so many species, all owe their development to a process of sexual selection which has led the discerning females to prefer the more ornamental of the males who sought them as partners. If any one will examine the exquisite shapes and gradations of color which are exhibited in the tail of the peacock, or of the lyre-bird, or even the coloration of the game-cock, he may perhaps imagine how prodigious must be the development of the Æsthetic sense in these species, in order that it may take account of every little betterment which leads towards more perfect beauty. As it will take the generations of Æsthetes many generations before they are able to "live up to" the level of their culture which is attained by the peacock's tail, it is not unreasonable for us to hold that in the appreciation of simple beauty in form and in color, the birds are far ahead of ourselves. It must not be supposed that our Æsthetic culture is to be reckoned below that of birds, though in our case the work embodies the delineation of ideas, while in the birds it is a matter of pure ornament. Nevertheless, taking the evidence which shows the way in which these creatures appreciate beauty in the three realms of form, color, and sound, it seems to me clear that while their intellectual life is low, their purely emotional experiences are probably more vivid than those of ordinary men.

As the joy of life is, in the main, even in ourselves the result of emotional experiences, we may fairly reckon, even on a priori ground, that the birds win a measure of happiness, though it be that of an unconscious kind, which is granted to no other living beings. Psychologically described, they might well be termed the group built for joy. Their bodies are, on the whole, the best constructed of all animals, except the insects. They suffer little from disease. We all see that their intercourse with each other is freer and merrier than that of other creatures. The wide range of their notes shows that in most forms they appreciate every little difference in the pleasure-giving changes of the day or the weather. They rejoice in the coming of each morning; they are sorrowful with the advent of each evening. They echo the distress of their kind in a readier way than any other forms. He is indeed a poor naturalist who overlooks this trait; for however deeply he may have delved, he has not won the jewel unless he appreciates this element of an unending joy which the bird-life continually offers him. From that life we may well believe that man is hereafter to derive some great and fruitful lessons.
