But what kind of nests do the rock nuthatches construct on their limestone walls? That is one of the most interesting features of the life of these birds. One writer[1] who has observed them in their native haunts describes the rock nuthatch as "an expert clay mixer and molder." The bird does not chisel out a nursery in the rock—no, indeed; his method of constructing his nest is as follows: Having found a little hollow or indentation on the rocky wall, he will erect a cap or dome of mortar over it, plastering the structure so firmly against the surface that no rain or storm or predaceous creeping thing can demolish it until long after it has been abandoned by the little architect. The circular base of the nest is ten or twelve inches in diameter. The dome is not entirely closed up, but a small orifice is left in the center, upon the edges of which a narrow neck or funnel, also made of mortar, is raised, the hole just large enough to admit the body of the bird. The funnel is about three inches long.
The building material employed is fine clay softened and glutinated with the bird's saliva and mixed with plant fibers, for the little mason does not believe in making bricks without straw. So well packed is the inch-thick wall that a stiff knife blade must be used to cut through it. While the natural color of the adobe cottage is ash-gray, and therefore harmonizes with the general hue of its surroundings, and also with the mezzotints of the builder, yet he sometimes decorates it with the gaily colored wings of moths caught in the chase and attached to the plaster while it is fresh. The rock nuthatch is as expert a mixer of mortar as the well-known cliff swallows of our own country, and his adobe dwellings bear a close resemblance to theirs.
It is interesting to note that the European nuthatch, while nesting regularly in tree cavities, sometimes also chooses the crannies of rocks, when he goes a little more extensively into the plastering business; but his skill is not so well developed as that of his oriental cousin, whose mud cottage is a model of its kind.
[1] The writer referred to is Mr. H. C. Tracy, to whose charming article in "The Wilson Bulletin," published at Oberlin, Ohio, I am indebted for all my material on the rock nuthatch.
A FEATHERED PARASITE*
*Reprinted from Appleton's "Popular Science Monthly," with additions.
Nothing could more clearly prove that a common law runs through the whole domain of Nature than the fact that in every division of her realm there seems to be a class of parasites. In the vegetable world, as is well known, there are various plants that depend wholly on other plants for the supply of their vital forces. And in the human sphere there are parasites in a very real and literal sense—men and women who rely upon the toil and thrift of others to sustain them in worthless idleness.
In view of the almost universal character of this law it would be strange if these peculiar forms of dependence did not appear in the avian community. We do find such developments in that department of creation. Across the waters there is one bird that has won an unenviable reputation as a parasite: the European cuckoo relies almost wholly on the efforts of its more thrifty neighbors to hatch and rear its young, and thereby perpetuate the species. Strangely enough, our American cuckoos are not given to such slovenly habits, but build their own nests and faithfully perform the duties of nidification, as all respectable feathered folk should. However, this parasitical habit breaks out, quite unexpectedly, it must be conceded, in another American family of birds entirely distinct from the cuckoo group.
In America the cowbird, often called the cow bunting, is the only member of the avian household that spirits its eggs into the nests of other birds. The theory of evolution can do little toward accounting for the anomaly, and even if it should venture upon some suggestions it would still be just as difficult to explain the cause of the evolution in this special group, while all other avian groups follow the law of thrift and self-reliance.
The cowbird belongs to the family of birds scientifically known as Icteridae, which includes such familiar species as the bobolinks, orioles, meadowlarks, and the various kinds of blackbirds, none of which, I am glad to say, are parasites. The name Molothrus has been given to the genus that includes the cowbirds. They are confined to the American continent, having no analogues in the lands across the seas. The same may be said, indeed, of the whole Icteridae family. It may be a matter of surprise to many persons that there are twelve species and subspecies of cowbirds in North and South America, for most of us are familiar only with the common cowbird (Molothrus ater) of our temperate regions. Of these twelve species only three are to be found within the limits of the United States, one is a resident of western Mexico and certain parts of Central America, while the rest find habitat exclusively in South America. A fresh field of investigation is open to some enterprising and ambitious naturalist who wishes to study several of these species, as comparatively little is known of their habits, and indeed much still remains to be learned of the whole genus, familiar as one or two of the species are. Their sly, surreptitious manners render them exceedingly difficult to study at close range and with anything like satisfactory detail.
Are all of them parasites? Probably they are—at least to a greater or less degree—except one, the bay-winged cowbird of South America, which I shall reserve for notice later on in this chapter. We might assert that our common cowbirds are the parasites par excellence of the family, for, so far as I can learn from reading and observation, they never build their own nests or rear their own young, but shift all the duties of maternity, save the laying of the eggs, upon the shoulders of other innocent birds.
These avian "spongers" have a wide geographical range, inhabiting the greater part of the United States and southern Canada, except the extensive forest regions and some portions of the southern states. They are most abundant in the states bordering on the upper Mississippi River and its numerous tributaries. On the Pacific coast west of the Cascade and Sierra Nevada mountains, they occur only as stragglers. The most northern point at which they have been known to breed is the neighborhood of Little Slave Lake in southern Athabaska. In the autumn the majority of these birds migrate to southern Mexico, although a considerable number remain in our southern states, and a few occasionally tarry for the winter even as far north as New England and southern Michigan.
The male cowbird looks like a well-dressed gentleman—and may have even a slightly clerical air—in his closely fitting suit of glossy black, with its greenish and purplish iridescence, and his hood of rich metallic brown covering his head, neck, and chest. He makes a poor shift as a musician, but his failure is not due to lack of effort, for during courtship days he does his level best to sing a variety of tunes, expanding and distorting his throat, fluffing up his feathers, spreading out his wings and tail, his purpose evidently being to make himself as fascinating as possible in the eyes of his lady love. One of his calls sounds like "spreele," piped in so piercing a key that it seems almost to perforate your brain.
One observer maintains that the cowbirds are not only parasitical in their habits, but are also absolutely devoid of conjugal affection, practicing polyandry, and seldom even mating. This is a serious charge, but it is doubtless true, for even during the season of courtship and breeding these birds live in flocks of six to twelve, the males almost always outnumbering the females. However, if their family relations are somewhat irregular, no one can accuse them of engaging in brawls, as so many other birds do, for both males and females seem to be on the most amicable terms with one another, and are, to all appearances, entirely free from jealousy. Who has ever seen two cowbirds fighting a duel like the orioles, meadowlarks, and robins?
In obtruding her eggs into the nests of other birds, Madame Cowbird is sly and stealthy. She does not drive the rightful owners from their nests, but simply watches her opportunity to drop her eggs into them when they are unguarded. No doubt she has been on the alert while her industrious neighbors have been constructing their domiciles, and knows where almost every nest in the vicinity is hidden. Says Major Charles Bendire: "In rare instances only will a fresh cowbird's egg be found among incubated ones of the rightful owners. I have observed this only on a single occasion." From one to seven eggs of the parasite are found in the nests of the dupes. In most cases the number is two, but in the case of ground builders the cowbird seems to have little fear of overdoing her imposition. Major Bendire says that he once found the nest of an oven-bird containing seven cowbird's eggs and only one of the little owner's.
If parasitism were the only crime of the cowbird one would not feel so much disposed to put her into the Newgate Calendar; but she not only inflicts her own eggs upon her innocent victims, but often actually tosses their eggs out of the nests in order to make room for her own. Nor is that all; she will sometimes puncture the eggs of the owners to prevent their hatching, and thus increase the chances of her own offspring. Whether this is done with her beak or her claws is still an open question, Major Bendire inclining to the belief that it is done with the claws.
Her finesse is still further to be seen in the fact that she usually selects some bird for a victim that is smaller than herself, so that when her young hopefuls begin to grow they will be able to crowd or starve out the true heirs of the family. In this way it is thought that many a brood comes to an untimely end, the foster parents having no means of replacing their own little ones when they have been ejected from the nest. However, I doubt whether the cowbird's impositions are usually so destructive as some observers are inclined to believe. I once found a bush sparrow's nest containing one cowbird and four little sparrows, all of which were in a thriving condition. The sparrows were so well fed and active that as soon as I touched the nest they sprang, with loud chirping, over the rim of their cottage and scuttled away through the grass. They were certainly strong and healthy, in spite of the presence of their big foster brother. Before they flitted away I had time to notice how the little family were disposed. The cowbird was squatted in the center of the nest, while his little foster brothers and sisters were ranged around him, partly covering him and no doubt keeping him snug and warm. They were further advanced than he, for while they scrambled from the nest, he could do nothing but snuggle close on the bottom of the cup.
A wood thrush's nest that I found contained two young thrushes and two buntings. All of them were about half fledged. Being of nearly the same size, the queerly assorted bantlings lived in apparent peace in their narrow quarters. I watched them at frequent intervals, but saw no attempts on the part of the foundlings to crowd out their fellow-nestlings. The cowbirds were the first to leave the sylvan roof tree. Thus it appears that the intrusion of the cowbird's eggs does not always mean disaster to the real offspring of the brooding family, but of course it often prevents the laying of the full complement of eggs by the builders themselves.
Even after the youngsters have left the nest the mother cowbird does not assume the care of them, but still leaves them in charge of the foster parents. It is laughable, almost pathetic, to see a tiny oven-bird or redstart feeding a strapping young cowbird which is several times as large as herself. She looks like a pigmy feeding a giant. In order to thrust a tidbit into his mouth she must often stand on her tiptoes. Why the diminutive caterer does not see through the fraud I can not say. She really seems to be attached to the hulking youngster. By and by, however, when he grows large enough to shift for himself, he deserts his little parents and nurses and seeks companionship among his own blood kindred, who doubtless bring him up in the way all cowbirds should go.
It is surprising how many species are imposed on successfully by the cowbird. The number, so far as has been observed, is ninety, with probably more to be added. Among the birds most frequently victimized are the phoebes, the song sparrows, the indigo birds, the bush sparrows, and the yellow-breasted chats. Even the nests of the red-headed woodpecker and the rock wrens are not exempt. Some species, notably the summer warblers, detect the imposture and set about defeating the purposes of the interloper by building another story to their little cottage, leaving the obtruded eggs in the cellar, where they do not receive enough warmth to develop the embryo.
While it is surprising that acute birds should allow themselves to be imposed on in this way, perhaps, after all, they look upon the cowbird as a kind of blessing in disguise; at least, he may not be an unmixed evil. They may act on the principle of reciprocity—that "one good turn deserves another." What I mean is this: In my rambles I have often found the cowbirds the first to give warning of the approach of a supposed danger. Having no domestic duties of their own, they can well secrete themselves in a tall tree overlooking the entire premises, and thus play the useful role of sentinel. This, I am disposed to believe, is one of the compensating uses of this parasite, and may furnish the reason for his being tolerated in birdland. And he is tolerated. Has any one ever seen other birds driving the cowbird away from their breeding precincts, or charging him with desperate courage, as they do the blue jays, the hawks, the owls, and other predatory species? He evidently subserves some useful purpose in the avian community, or he would not be treated with so much consideration.
A young cowbird that I purloined from the nest and tried to rear by hand did not prove a pleasant pet. He was placed in a large cage with several other kinds of young birds. At first he was quite docile, taking his food from my hand and even allowing some of his feathered companions to feed him; but in a few weeks he grew so wild and manifested such a fierce desire for the outdoor world that I was glad to carry him out to the woods and give him his freedom. A young red-winged blackbird and a pair of meadowlarks developed a different disposition.
The dwarf cow-bird (Molothrus ater obscurus) is similar to his relative just described, except that he is smaller and his geographical range is more restricted. He is a resident of Mexico, southern Texas, southwestern Arizona, and southern California. His habits resemble those of the common cowbird. Another bunting having almost the same range, although a little more southerly, is the red-eyed cowbird, which is larger and darker than our common cowbird and has the same parasitical habits.
In South America three species have been studied by Mr. W. H. Hudson, who, in collaboration with Mr. P. L. Sclater, has published a most valuable work on Argentine ornithology. One of these is called the Argentine cowbird (Molothrus bonariensis). It is a blue-blooded parasite, and has been seen striking its beak into the eggs of other birds and flying away with them. The males, it is said, show little discrimination in pecking the eggs, for they are just as likely to puncture the cowbird eggs as those of other birds. Every egg in a nest is frequently perforated in this way. These buntings lay a large number of eggs, often dropping them on the ground, laying them in abandoned nests, or depositing them in nests in which incubation has already begun, in which case all of them are lost. However, in spite of this wastefulness the birds thrive, thousands of them being seen in flocks during the season of migration.
And, by the way, a description of their habits by Mr. Hudson has thrown interesting light on the subject of migration in the southern hemisphere. South of the equator the recurrence of the seasons is the exact reverse of their recurrence north of the equator, and therefore the breeding season of the birds is in the autumn instead of the spring; the flight from winter cold occurs in the spring instead of in the autumn, and is toward the north instead of toward the south. Thus, in February and March the Argentine cowbirds are seen flying in vast battalions in the direction of the equatorial regions—that is, northward—in whose salubrious clime they spend the winter. As our northern autumn draws near and the southern spring approaches these winged migrants take the air line for their breeding haunts in the Argentine Republic and Patagonia. At the same time the migrants of the northern hemisphere are pressing southward before the blustering north wind. It all seems wonderful and solemn, this world-wide processional of the seasons and the birds.
Naturally one would expect to find some other eccentricities in this aberrant family besides that of parasitism, and in this expectation one is not disappointed. There are two other species of cowbirds in the Argentine country—the screaming cowbird (Molothrus rufoaxillaris) and the bay-winged cowbird (Molothrus badius). The latter is only partly a trencher on the rights of other birds—only half a parasite. Indeed, it sometimes builds its own nest, which is quite a respectable affair; but, as if to prove that it still has some remnants of cowbird depravity in its nature, it frequently drives other birds from their rightful possessions, appropriates the quarters thus acquired, lays its eggs into them, and proceeds to the performance of its domestic duties like its respectable neighbors. Its virtue is that it never imposes the work of incubation and brood rearing on any of its feathered associates, even though it does sometimes eject them from their premises.
But what is to be said of the screaming cowbird? Instead of inflicting its eggs on its more distant avian relatives, it watches its chance and slyly drops them into the domicile of its bay-winged cousins, and actually makes them hatch and rear its offspring! This seems to be carrying imposture to the extreme of refinement, or possibly developing it into a fine art, and reminds one of those human good-for-naughts who "sponge" off their relatives rather than go among strangers.
Before closing this chapter I must call attention to one of the most surprising discoveries ever made by an American observer of bird ways. It was reported some time after my article on the cowbird was first published in Appleton's "Popular Science Monthly." The observer was Joseph F. Honecker, whose statement was printed in "American Ornithology" for June, 1902, and runs as follows:
"As ornithologists and all bird students think and believe that the cowbird will build no nest, but always lays in the nests of other birds, I am glad to give the results of my experiments. In order to get the desired results, in the spring of 1899 I secured a pair of cowbirds and placed them in a large cage, cared well for them, and supplied them with plenty of nesting material. To my surprise, the female built a nest, laid four eggs, hatched them, and reared the young, and on July twenty-eighth, young and old were given their freedom. This will show that the cowbird will build a nest and care for its young in captivity, while in its wild life it has never been known to do so."
A BLUE CANNIBAL*
*Reprinted by permission from "The Evening Post," New York.
In his coat of light blue, trimmed with white and black, bearing his crest jauntily atop of his head, the blue jay presents an attractive picture. And, indeed, although I myself feel that the Baltimore oriole, the scarlet tanager, the ruby-throated hummingbird, and many of the wood warblers carry off the palm for brilliancy of plumage, there are persons who declare that the jay is the most handsomely colored bird in our temperate regions.
While the jay dons an engaging attire, not much can be said in the way of eulogy for his vocal talents or acquirements. Many of his calls are harsh, penetrating, and even raucous. Frequently, too, he indulges in a great to-do over nothing, fairly splitting your ears with his noisy cries. I have said it is a to-do over nothing, though Mr. Jay may think he has the best reason in the world for making a fuss. Often espying some coveted prize on the ground in my back yard, instead of quietly dropping down and taking it, he and his companions would dash about in the trees, swing their bodies sidewise and up and down in an excited way, and scream at the top of their voices, sometimes drawing me out of the house to see what had gone wrong in Jaydom. They seemed to be determined to attract the attention of every person on the premises to the fact that they wanted that morsel on the ground, but were afraid to venture down after it. Perhaps they meant by their objurgations to test their human neighbors, to ascertain whether any of them were prowling about with a gun or a sling, ready to do them harm. If there should be any such prowlers, probably the jays meant to induce them to come out of their ambush, to show themselves in the open, and give their jayships a chance to escape. Bird psychology, as you will have occasion to note more than once, is a good deal of an enigma. How often we would give a handsome bonus to a bird if he would let us know precisely what he was thinking about!
Although no musician, the jay has quite an extensive vocal repertory. Besides his loud, challenging call, he frequently utters a series of calls that have a pensive quality and that fill the mind with an indefinable foreboding, especially on chill autumn days when all the woods are bare and gray and the wind is moaning through the boughs. Sometimes when a jay is hidden in a copse, he utters a low, scolding sputter, that seems to express the very quintessence of disgust. It is simply his way of telling you what he thinks of a man who goes prowling about without leave in the precincts of the birds.
Have you ever heard the jay's brief musical roulade? It is only a wisp of melody, rarely rich and suggestive, heard a moment, then gone. You know something sweet has passed by, but something so brief and elusive that you scarcely know what it was. Long after it has dropped on your ear, it continues to haunt your memory, and you try again and again to reproduce it, but in vain. It has a kind of gurgling quality, as if the bird were pressing his notes through an aqueous lyre, if such a conception is possible. Besides, I have, on more than one occasion, heard a jay warble a soft, reserved little lay that was continued for many minutes. It sounded very like the song of the brown thrasher, much modulated and partly uttered under its breath—a sort of flowing, rythmical melody.
A question that disturbs all bird lovers more or less is this: Does the fine white vest of the jay cover a bad heart? Is he really a thief, a nest robber, or even worse, a cannibal, in plumes? May the guardian spirit of all feathered folk forbid that I should blacken the reputation of any bird, yet honesty compels me to give an affirmative answer to the foregoing question. I hasten, however, to say that I do not believe he is as black as he has been painted by some observers, who seem to delight in making out a verdict of capital guilt against him. Although a predatory bird, he is not engaged all the time in bloodthirsty pursuits, but only while his young are in the nest clamoring for food. What are some of the proofs of his vandalism? I will mention a few of them.
First, almost all the small birds make uncompromising war upon him, especially in the breeding season, and many of them show signs of dire distress when he goes near their nests. They often utter pitiful cries, droop their wings, and the bravest of them dash at him savagely, giving him many a cuff on the head and back. The wood pewee and the kingbird succeed, I think, in driving him away; but the vireos and warblers, being so much smaller, suffer greatly from his depredations. If there were no real cause for it, these birds would not be filled with panic and rage on account of the jay's presence. There is strong presumptive evidence that they know him for an outlaw only too well.
The following incident will furnish positive proof of the jay's cannibalistic proclivities: One spring my little boy brought home from the country a young house wren, thinking it would make a delightful pet. It was quite well fledged, but its short tail and white mouth border proclaimed the tenderness of its youth. Fearing that the little thing could not be reared by hand, as it refused all our proffered tidbits, and chirped continually for its parents, I persuaded the lad to give it its freedom. A mother wren living on our premises seemed inclined to adopt the little waif, and we decided to put it under her care. No sooner was the youngling let out of the cage than it flew to the side of the house and began to scramble up the brick wall. It had a hard tug, but at length succeeded in reaching a resting place on a window-shutter of the second story.
Presently the mother wren heard its calls and paid it a visit; but instead of feeding it, she seemed very anxious to drive it away, knowing, no doubt, that there were predaceous enemies in the neighborhood. In her attempts to drive it into hiding, she pecked it on the head and in the mouth. Then she dropped down into a thicket and secured a green worm, with which she flew up to the chirping waif's perch; but I could not make out that she fed the birdling, though she thrust the worm toward its open mouth. Soon after she had gone off the second time, the little bird clambered around the corner of the wall to the lower side of the house, where it rested a while on a narrow shelf.
All this time my boy and I were watching it intently. Suddenly a blue jay came flying over from one of the trees of an adjacent yard, moving in a rapid, stealthy way. First it plunged into an apple tree at the corner of the house; then, before I could collect my wits enough to know what was happening, it darted over to the brick wall, seized the little wren with its bill, and bore it off. The mother wren followed, uttering a pitiful chatter, while the little victim called loudly for help. The blue kidnapper darted to a tree in my neighbor's yard, where he put his booty under his claw on a limb, holding it by one slender leg, while its body dangled below. Hoping still to rescue the little captive, I sprang over into the adjacent yard with a loud shout and much waving of my hands; but my vigorous efforts only caused the jay to pick up the wren in its bill and continue its flight, and neither wren nor jay was seen by me again. This incident furnishes unimpeachable testimony against the character of the blue-coated Robin Hood. There was no faltering or hesitancy in his conduct, but he seized and carried off his little victim as if he were to the manner born, and had become hardened by practice in depredations of the sort.
A farmer once related the following incident to me: A pair of chipping sparrows had built a nest in a bush in his front yard. One day after the little ones had arrived, he heard a distressed chirping coming from the parent birds, and on going to the front yard, he caught a blue jay in the act of picking a callow bantling from the chippie's nest. Holding it in his bill, the jay flew across the field with his prize, and presently returned and bore off a second nestling. By this time the farmer's ire was aroused; he bolted into the house and secured his shotgun, and when the marauding jay came back on the third trip on robbery intent, the man brought him to the ground with a shot that ended his career.
Yet the jay is not wholly bad—indeed, not even half bad. Before me lies a valuable pamphlet entitled "The Blue Jay and His Food," written by F. E. L. Beal, Assistant Biologist of the Department of Agriculture at Washington, whose researches have converted him into something of an apologist for our blue gentleman in feathers. He dissected the stomachs of 292 jays, collected during every month of the year in twenty-two states, the District of Columbia, and Canada. After stating that mineral substances in the stomachs examined averaged over 14 per cent of the total contents, Mr. Beal says:
"The real food is composed of 24.3 per cent of animal matter and 75.7 per cent of vegetable matter, or a trifle more than three times as much vegetable as animal. The animal food is chiefly made up of insects, with a few spiders, myriapods, snails, and small vertebrates, such as fish, salamanders, tree frogs, mice, and birds. Everything was carefully examined which might by any possibility indicate that birds or eggs had been eaten, but remains of birds were found in only two, and the shells of small birds' eggs in only three of the 292 stomachs. One of these, taken on February tenth, contained the bones, claws, and a little skin of a bird's foot. Another, taken on June twenty-fourth, contained the remains of a young bird. The three stomachs with bird's eggs were collected in June, August, and October, respectively. The shell eaten in October belonged to the egg of some larger bird like the ruffed grouse and, considering the time of year, was undoubtedly merely an empty shell from an old nest. Shells of eggs which were identified as those of domesticated fowls, or some bird of equal size, were found in eleven stomachs, collected at irregular times during the year. This evidence would seem to show that more eggs of domesticated fowls than of wild birds are destroyed, but it is much more probable that these shells were obtained from refuse heaps about farm-houses."
Mr. Beal's dissections are very significant, proving that the jay is not only not so destructive of eggs and bantlings as was supposed, but also that he destroys many noxious insects, and is, therefore, a bird of real economic value. The great bulk of his insect diet consists of beetles, grasshoppers, and caterpillars, with a few bugs, wasps, and flies, and an occasional spider and myriapod. The average of insect food for the whole year was 23 per cent, varying from less than 1 per cent in January to over 66 per cent in August, and it is gratifying to know that predaceous beetles and tent caterpillars form a large part of the jay's bill of fare.
His demands upon domesticated fruits and grains are comparatively light. He cares more for acorns and mast than for corn. The last he does not greatly relish, but eats it chiefly when the snow covers his favorite food. It is a little surprising that he occasionally varies his diet with fish, salamanders, tree frogs, mice, and shrews. Mr. Beal's conclusion is put in the following sentence, which closes his valuable monograph: "In fact, the examination of nearly three hundred stomachs shows that the blue jay does far more good than harm."
An important question, therefore, from more than one point of view is: Should we ever kill the blue jay? Perhaps as sensible an answer to that question as can be given is this: We should by no means engage in a war of extermination upon the jays, but it might be wise, when they become too abundant, to thin out their numbers somewhat by shooting some of them or driving them away. It can scarcely be denied that if they are permitted to thrive without hindrance, and grow to large numbers, they will become sorely destructive of the eggs and nestlings of more desirable birds. I assure you, however, that I make this statement with reluctance and reserve, for the handsome blue-coat is one of our most cunning and interesting birds, and would be greatly missed if he were exterminated.
The blue jay is also a plucky bird, as I discovered one day not so very long ago. A pair of jays had a nest in a little park in front of my house, and one day one of the youngsters, which were still unable to fly, dropped to the ground. Fearing the cats or evilly disposed boys might catch the little fellow, I thought to do him and his parents a good turn by catching him and putting him up in one of the trees beyond the reach of his enemies. After quite a chase I succeeded in catching him. But the parent birds, flitting and calling in the trees, did not understand my well-meant intentions, and so one of them swung down and struck me on the top of the head with so much force that, either with his bill or his claws; he punctured the skin and made the blood come, leaving a scar on my crown for quite a while. The pesky thing! I think he might have known that I was his friend—but he didn't, his instinct not being a sure guide that time. But who can blame him? Not an hour afterwards the youngling again fell to the ground, when some children found it and killed it without the least excuse for their action. In such a case how could the parent birds distinguish between friend and foe? They found their little one lying dead on the ground, and mourned for it with heart-broken cries.
Some things cause a great to-do in the jay world. One day, while I was living in Kansas, the skeleton of a jay, with the feathers still attached, was found in the rubbish of an ash-pile in my rear yard, and exposed to view. An hour later a half dozen or more jays were flinging about in the peach tree above the feathers of their dead comrade, screaming at the top of their voices, "juking" their bodies, as is their wont when excited, and glaring at the disheveled plumes on the ground. If it was a funeral service, it certainly was a demonstrative one, and I do not believe that their grief and terror were affected.
A HANDSOME SCISSORSTAIL*
*Reprinted by permission from "American Ornithology," with important additions.
In order to study the scissorstailed flycatcher (Milvulus forficatus), of which some friends had told me again and again in a glow of enthusiasm, I made a trip to southern Kansas and northern Oklahoma. Several days passed before an individual of this species put in appearance, as the scissorstails, which are migrants, had not yet returned from their winter quarters in a more southern clime, and so I had to wait for their arrival.
One day a friend and I were driving along a country road over the prairie, when a quaint bird form went swinging from the wire fence by the roadside toward a clump of willows in a shallow dip of the prairie. Dashing after him, I heard a clear, musical call that proclaimed a bird with which I had not yet become acquainted.
In a few moments he flew from the tree. My binocular was fixed upon him as he went flitting across the field and presently alighted on the ground. My surmise was correct; it was the scissorstail flycatcher, one of the most unique and handsome birds belonging to our American avifauna, one that merits more than a passing notice. To see him perched on a fence, or swinging gracefully through the air, and hear his bell-like calls and whistles makes you feel as if you were suddenly transported to a foreign land, like Australia or Borneo, where so many feathered curios are to be found.
In a fever of excitement I followed the bird, which presently flew back to the fence by the roadside. He flitted from point to point as my friend and I slowly pursued him, giving us an exhibition of his scissoring process. Sometimes he would alight on a post, then on the barbed wire, usually sitting flat on his breast. When open, the tail is bicolored, the outer border all around being white and the inner black. His general color is hoary ash, paler, almost white, below, giving out a slight iridescence in the sunshine; his wings are blackish, with white trimmings; his flanks are stained with salmon-red, and when his wings are spread, there appears a large blotch of scarlet at the inner angle of the intersection with the body. One individual that I afterwards saw wore a scarlet epaulet, which was almost concealed by the other plumes when the wing was closed, but was clearly seen when it was extended. An orange or scarlet gem adorns the crown, but is so well hidden by the other crest feathers that it is seldom noticed.
My friend and I were privileged to witness a rare and attractive scissorstail show, more gratifying than any circus performance. A loggerhead shrike suddenly appeared on the scene, and made an assault on the flycatcher. The two birds went gyrating, zigzagging, see-sawing through the air in a perfect jumble of white and black and ash. It must be remembered that the shrike himself makes a handsome picture on the wing, and when you come to mix up a scissorstail and a shrike in inextricable confusion, you have a feathery display worth seeing.
Nor was that the end of the exhibition, for in a moment a second scissorstail, the precise facsimile of the first, appeared from somewhere, and the two flycatchers combined against their enemy. Then for a few minutes there was such a chaos of shrike and scissorstail that we could scarcely tell which was which. By and by the shrike wheeled away, when, as if to bring the gladiatorial show to a climax, the scissorstails engaged in a set-to that was really wonderful, coming together in the air, whirling around and around, rising in a spiral course, opening and closing their beautiful forked tails in quick succession, the black and white trimmings flashing momentarily, then disappearing, until the contestants finally descended, parted in the most graceful manner, and alighted on separate fence posts, none the worse for their melee.
In the evening I returned to the enchanted spot, but the scissorstails had disappeared. Not having had my fill of these charmers, I stopped, on my return home, for a day at Wellington, Kansas, where I was so fortunate as to find three birds of this species, who permitted me to watch them to my heart's content. They are not shy birds, but fly in a graceful, leisurely way from post to post along the fence as you walk or drive, sometimes sitting quietly to let you pass by. In this respect their habits are much like those of their cousin, the kingbird.
As his name indicates, our bird is the proud possessor of a genuine scissorstail, composed of two long, slender prongs that are spread far apart under certain conditions of flight. Let me describe the process minutely, for it is unique here in North America where fork-tailed birds are rare.
When the bird starts up from a perch, he spreads apart the prongs of his tail for a moment, as if to give himself a spring; then he closes them in a single slender stem, tapering outward to a point, keeping them closed during prolonged flight, and just as he sweeps down to another perch, he opens his ornamental scissors again, shutting them up as soon as he has settled upon his resting place. He does not open and close his tail at regular intervals during flight, as might be supposed, but keeps it closed until he descends to a perch, when it is opened for a moment in the act of alighting. However, if he has occasion to wheel or make a sudden turn in the air, either for an insect or in a playful prank, his scissors fly open, one might almost say spontaneously, no doubt serving the double purpose of rudder and balancing pole. When closed, the tail is very narrow, looking almost like a single plume. On the perch (except when he desires to shift his position, when he also makes use of his wings) his tail is closed. Therefore the picture of this bird in Dr. Coues's "Key to North American Birds" is not accurate, for it represents our bird in the sitting posture with the tines of his fork spread apart. If the wings were outstretched, representing the bird in the act of alighting or shifting his position, the picture would be true to scissorstail life.
The range of these birds is somewhat restricted, and for that reason, doubtless, so little is known about their habits. According to Ridgway, their proper home is in eastern Mexico and the southwestern prairie districts of the United States, though many of them come north as far as southern Kansas and southwestern Missouri to spend the summer and rear their families. In winter they go as far south as Costa Rico. Restricted as their habitat is, it is curious to note that they are "accidental" in a few unexpected places, such as Key West, Fla., Norfolk, Va., and also in several localities in New England, Manitoba, and Hudson Bay Territory. Prof. W. W. Cooke, of Colorado, says they are "rare, if not accidental," in that state. To show that our birds are unique, it is relevant to say that there are only two species of scissors-tailed flycatchers in North America, which have the genus Milvulus all to themselves. The other member of the genus is the forked-tailed flycatcher (Milvulus tyrannus), a resident of tropical America, migrating north normally as far as southern Mexico. He is a sort of southern twin of our scissorstail.
The nests of the scissorstails are set in the crotches of trees in the neighborhood of country homes on the prairie. Considering the size of the birds, their nests are quite small, not so large as those of the brown thrashers, though the cup is deeper and the architecture more compact and elaborate. A friend describes a nest which he found on a locust tree about sixteen feet from the ground. It was made mostly of dry grass and locust blossoms, with here and there a piece of twine braided into the structure. It had no special lining, but the grass was more evenly woven on the inside of the cup than elsewhere.
From three to five eggs are deposited. The ground color is white, either pure or creamy, sparingly mottled with rich madder-brown and lilac-gray, the spots being thicker and larger on the larger end. While the nest is undergoing examination, the owners circle and hover overhead, much after the fashion of the red-winged blackbirds, expressing their disapproval in loud and musical calls, and displaying their rich scarlet decorations.
My descriptions have related only to the male bird, whose beautiful forked tail is nine to ten inches long, and whose colors are clear and more or less intense. His spouse resembles him, but is slightly smaller, while her tail, though forked like her mate's, is from two and a half to three inches shorter. The salmon and scarlet ornaments on the sides, flanks, and axillars are paler than those of her lord, and the scarlet spot shows very indistinctly on her occiput. The young of both sexes don the dress of the mother bird during the first season, save that they fail to adorn themselves with a scarlet gem on the crown.
Like all the members of the flycatcher group, the scissorstails capture insects while on the wing, making many an attractive picture as they perform their graceful and interesting evolutions in the air.
It was a year or two later that I saw a scissorstail performing his ablutions in the northwestern part of Arkansas. How do you suppose he went about it? Not in the way birds usually do, by squatting down in the shallow water, twinkling their wings and tail, and sprinkling the liquid all over their plumage. No; this bird has a reputation to maintain for originality, and therefore he took his bath in this manner: First he perched on a telegraph wire by the roadside; then he swung gracefully down to a little pond, dashed lightly into the water, giving himself a slight wetting, after which he flew up to his original perch on the wire. A minute or less was then spent in preening his plumes; but they were not moist enough to suit his purpose, so he darted down to the pond again, making the spray rise as lie struck the water; then up to his perch he swung again, to arrange his feathers; and this was repeated a number of times, till his toilet was completed. It would not be safe to risk saying that the scissorstail always takes his bath in this way; but I know this one did. I once saw a kingbird doing the same thing, and so it may be a fashion in flycatcher circles.
I am minded, in order to make this monograph more complete, to borrow a couple of paragraphs from Mrs. Bailey's "Handbook of Birds of the Western United States." She has studied the bird in the Southwest, and gives the following graphic description of the bird and its habits:
"One of his favorite performances is to fly up and, with rattling wings, execute an aerial seesaw, a line of sharp-angled VVVVVVV's, helping himself at the short turns by rapidly opening and shutting his long white scissors. As he goes up and down he utters all the while a penetrating scream, Ka-quee-ka-quee-ka-quee-ka-quee-ka-quee, the emphasis being given each time at the top of the ascending line.
"Frequently when he is passing along with the even flight of a sober-minded crow, and you are quietly admiring the salmon lining of his wings, he shoots rattling into the air, and, as you stare after him, drops back as suddenly as he rose. He does this apparently because the spirit moves him, as a boy slings a stone at the sky, but fervor is added by the appearance of a rival or an enemy, for he is much like a Tyrannus in his masterful way of controlling the landscape. He will attack caracaras and white-necked ravens, lighting on their backs and giving them vicious blows while screaming in their ears."
AN ALPINE ROSY FINCH*
*Part of the material used in this chapter has already appeared in the author's work entitled "Birds of the Rockies," but it is here printed in different form, that of a monograph, with a number of additional facts. The writer feels that the readers of the present volume will relish at least a taste of bird study among the alpine heights of the Rocky Mountains. The article is reprinted from the "Denver Post," whose courtesy is hereby acknowledged.
The common name of the subject of this sketch is the brown-capped rosy finch; in the scientific works on ornithology he is called the brown-capped leucosticte. He is certainly a bird of peculiar habits and out-of-the-way preferences. Should he send you his card from his summer residence, it would read something like this: "At home in the mountains of Colorado, from 10,000 feet above sea-level to the summits of the highest peaks." There is only one other bird in Colorado that has so high a summer range, and that is the white-tailed ptarmigan, usually called, in hunter's parlance, the "mountain quail."
The rosy finch is slightly larger than the bluebird. His general color is light brown, suffused with a beautiful pink or rosy tint, the dark shaft lines and pale edges of the feathers of the back giving it a striped appearance. The forepart of the top of the head is blackish, and the cap is brown, from which he gets the qualifying adjective of his name. In the best nuptial plumage the rosy coloring is heightened to an intense crimson, especially on the wings, tail coverts, and the under parts. The female's attire is paler and duller of tint, the pink being sometimes almost obsolete. Oddly enough, in summer the bills of these birds are deep black, while in winter they become yellow, only the tip remaining black or blackish.
My introduction to the leucostictes occurred on the summit of Pikes Peak, at an elevation of 14,147 feet above the level of the sea. With exhausting toil I climbed the peak one night, and the next morning, when I stepped out of the signal station, where I had secured lodging, a flock of the brown-caps were flitting merrily about the garbage heap, helping themselves to an early breakfast. Their blithe chirping sounded very much like conversation all among themselves, and proclaimed two pleasant traits of character—cheerfulness and good temper. It was evident that they were happy and contented in their alpine home, in the upper story of the world, the rare, cool, exhilarating air, the majestic panoramas, and the unlimited freedom all contributing to the blithesomeness of their spirits. The keepers of the signal station told me that the birds came to the refuse pile every day for their meals.
Two years later, on the twenty-eighth of June, a friend and I clambered up Grays Peak, which is several hundred feet higher than Pikes Peak. It was a long and toilsome climb, winding about the snowbeds of the mountain side. Sometimes we scaled straight up the acclivity on "all fours," throwing ourselves down on the rocks at frequent intervals to rest our aching limbs and fill our lungs with the rarefied air; up and up and up, until at last, with a long pull and a strong pull, we stood on the sky-haunting ridge above all the surrounding elevations, looking down upon the rest of the world, which seemed to be crouching at our feet.
Long before we reached the summit we were saluted by a new bird voice—one that had not been heard farther down the mountain. It was a cordial chirp, which seemed to bid us welcome to the alpine region and to assure us that there was no risk in climbing to these sky-aspiring summits. A glance proved that our little salutarian was the brown-capped rosy finch, which I had not seen since my ascent of Pikes Peak. Down in the green, copsy valley at the base of the mountain we had met with the white-crowned sparrows and Wilson and Audubon warblers; then, as we began to climb the steep shoulder of the mountain, the American pipits had become our comrades, accompanying us about half way up the elevation; now all other birds had disappeared and we entered the arctic precincts of the leucostictes, which, like a gallant bodyguard, escorted us to the summit, cheering us on with their friendly chirping. The bailiwicks of the pipits and the rosy finches slightly overlapped, as did also those of the pipits and the white-crowned sparrows near the great mountain's base. However, no pipits ventured to the upper story of this elevated region—at least, not at the time of our visit, although they may have ascended to the summit later in the season.
How blithe and cheerful were the pretty leucostictes! Now they darted fearlessly about in the air over the summit and the gorges; now they alighted on the wall of the dilapidated old signal station, and anon hopped and flitted about over the extensive snow beds, picking up dainties that were evidently to their taste, all the while beguiling the time with their companionable, half-musical chirping. So far as I observed, they have no real song. If they have, it is strange that they did not furnish a sample of their lyrical gifts on so calm and sweet a summer day in the season of courtship.
What billsome morsels did they find on the snow? We examined their white tablecloth and found a number of small beetles and other insects creeping up through it or crawling around over its surface. Thus Nature spreads her banquet everywhere for her feathered children.
One cannot help falling into the speculative mood as one reflects on these little birds and their remarkable habits. Why do they, of all birds, choose the highest mountain peaks for their summer homes? Might the cause be physiological? Are their lungs, muscles, and nervous systems so constructed as to be adapted to a dry, rare, crisp atmosphere, which would prove injurious, perhaps fatal, to birds of a different structural organization? Who can tell? At all events, they live on these towering elevations all summer long, woo their plainly-clad mates, build their nests, and rear their happy families.
Their nests are set amid the rocks, and are quite bulky, the walls composed of grasses and the lining consisting of soft feathers. In order to procure the grasses required, they must descend at least to the belt of scant vegetation just below the region of bare rocks and boulders. Where they get the downy feathers for the carpet of their nurseries I have not been able to ascertain. No nest has yet been discovered below an elevation of 12,000 feet. Our little bird may, indeed, be called a "haunter of the sky." The height of the breeding season is in the latter part of July. The broods having left the nests, old and young gather in small flocks and range over the peaks and ridges, feeding on the insects to be found on the fields of snow.
No less interesting are the habits of these birds in winter. In October and November most of them descend only to the timber line, where they remain throughout the winter, save as they are driven down into the denser forests by the fierce tempests of this arctic region. What feathered Vikings they are! They do not even make for themselves snow huts for protection from the winter storms. However, a few descend almost to the base of the foothills, while others—perhaps the less hardy—seek a blander climate in the northern part of Mexico.
There are in North America four other species of the genus Leucosticte; the Aleutian, whose habitat is the Aleutian and Prybilof islands and east as far as the island of Kadiak; the gray-crowned, which breeds in British America near the Rocky Mountains, comes to Colorado in winter, and has been taken as far east as western Iowa; the Hepburn, dwelling chiefly in the mountain ranges of the Pacific coast, breeding mostly in the far North, and in winter coming as far south and east as Nevada and Colorado; and, lastly, the black leucosticte, which winters in the central latitudes in the Rocky Mountains and whose summer range and breeding home is unknown to men of science.
HAPPENINGS BY THE WAY
If one were to keep on writing monographs of all our interesting avian species, the books that would result would make a good-sized library. The few examples that have been given will illustrate what can be done in this direction with the help of the field glass and the handbook. A few chapters will now be given on what might be called "odds and ends of bird life," and these are written not only for the information they may impart, but also for the purpose of showing how many interesting facts can be gathered along the way by the method of bird study commended in our opening chapter.
The prince of American ornithologists, Dr. Elliott Coues, has somewhere said that he would travel a long distance to discover a new kind of bird, or even to ascertain a new fact about a familiar species. I would applaud and echo that sentiment, for by all means let us have bird news that really is news, instead of revamping the familiar facts again and again, as some amateurish writers do. While I am not able to add any new species to science, I have made note of many pleasing incidents in the bird realm, and these, I venture to hope, may be of not a little general interest.
There is the companionable white-breasted nuthatch which goes scudding up and down the tree trunks with as much ease and aplomb as a fly gliding over a window-pane. I have already told you something about him. I had long been aware that he wedged grains of corn, sunflower seeds, and kernels of nuts in the crannies of the bark; but one day he invented a trick that was a surprise to me. It occurred at a summer resort in northern Indiana, where I noticed a nuthatch hitching up and down and around the slender stem of a sapling, pausing at intervals to thrust something into the crevices of the bark. My curiosity led me to pry into the bird's affairs. Stepping smartly forward, I drove him away, not heeding his vigorous protest of "yank, yank," and examined the bark of the sapling. What did I discover? A colony of black ants were scuttling up and down the tree, apparently under stress of great excitement; and good reason they had, for here and there one of their number was tightly wedged into a chink of the bark, often doubled up into a bow or an angle. They were not killed, at least not all of them, for they were still wiggling their legs and antennas; but they were evidently benumbed, or some of their backs were broken, and they were fastened so securely in the fissures that they could not escape. Does it not look as if the forehanded nuthatch was laying by a supply of ants for a coming time of hunger?
One day a family of wood pewees visited the dooryard of my tent. A multitude of gnats circling about in the air, seemed to be precisely to the taste of the pewee parents and their hungry bairns. The bantlings sat chirping in the saplings, or flitted from twig to twig, twinkling their wings in the coaxing way that is characteristic of young birds, while the papa and mamma swung out into the air, nabbed the insects on the wing, and flew back to the trees, describing many circles, ellipses, and festoons of rare grace and beauty. The snapping of their mandibles could often be heard as they closed upon the fated insects. Most of the gnats thus captured were thrust into the mouths of the young birds, the parents dashing up to them and feeding them without alighting. As lavish a minstrel as the pewee pater familias is under most circumstances, that morning he was too busy to tune his wind harp.
Speaking of the voracious appetites of birds, as exhibited by the young pewees, which never seemed to get enough, I am reminded of something I witnessed one day in a deep, wooded hollow. A red-eyed vireo suddenly appeared in the branches above me, holding an immense green worm in his beak. Then followed a tussle for the "upper hand" that was worth seeing. The bird, holding its squirming victim by one end, proceeded to beat it against the limb, though it was almost too big and recalcitrant for him to handle. Presently the vireo, after a good deal of effort, succeeded in passing his quarry through his bill from end to end, thus reducing it to somewhat smaller dimensions. Still, it was a large morsel for so small a diner.
However, there were some intimations that the bird intended to bolt the worm whole. And that was just what he was planning to do! What a struggle ensued! I would have wagered that the little gourmand had reckoned without his host when he undertook to swallow that immense worm. He twisted his neck this way and that, gulped and squeezed and pried, until I feared he would burst his throat open. At length the worm was partly bolted, but it seemed to stick fast, and the bird stood there with his mandibles pressed far apart, the end of his dinner bulging out of his mouth, and I felt uneasy for a time lest he should choke to death before my very eyes. But, after resting a minute, he gave his neck a number of convulsive twists, and at last succeeded in forcing the unwilling worm down his throat, after which he wiped his bill on the limb with a self-satisfied air and flitted away as happy as a lark, knowing that his faithful craw would do the rest.
A slate-colored junco did a pretty thing in the woods one day of early spring—much more pleasing to see than the incident just described. He had rinsed his feathers in a pool of the little stream down in the hollow, and now he was squatting flat on his belly on the ground in a soft bed of brown leaves, preening and primping his plumes with his little white, conical bill. Now he gave his quills a deft touch, now the feathers of his wing, now those of his dainty breast. Lying there in the sun he presented a perfect picture of feathery laziness. Many a bird I have seen arranging his toilet after a bath while perching on a limb or a twig, and even, as in the case of the brown creeper, while clinging to the bole of a tree, but never before did I see one doing this while lolling on the ground. He was not sick or hurt, simply lazy; for when I went near him he flew away as chipper as a bird could be.
The rambler not only sees many of these pretty bird ways, but he sometimes has a hearty laugh at the birds' expense. During one of my outings a blustering whirlwind started on the summit of a small hill scantily covered with scrub oak. It seized the dead leaves and twirled them about as if in a spasm of anger; then it went scurrying noisily down the steep incline, flinging itself against a couple of large brush heaps in the hollow where a number of fox and Harris sparrows were concealed. They had imagined themselves safe in their brushy covert. Suddenly the whirlwind struck their hiding place with a clang and clatter, sending the birds in a wild panic in every direction. They did not seem to know what had struck them, and, as the wanton breezes tossed them this way and that, they expressed their astonishment in loud and frightened chirping. All over and no harm done, the bird lover burst into a peal of laughter at the discomfiture of his feathered neighbors, who looked at him as if they did not know what to make of his untimely hilarity.
Then, too, one cannot be an observing rambler without stumbling upon some exceedingly odd avian pranks, as the following description will indicate: One day I was sitting on the steep bank of a wooded ravine watching several rare little birds, hoping to discover some of their nests. Presently the susurrus of the hummingbird was heard, and a moment later two ruby-throats, a male and a female, flashed into view on the slope below me. The tiny madam settled on a twig near the ground, while her ruby-throated spouse performed one of the queerest antics I have ever witnessed in featherland. He began to swing back and forth in an arc of almost half a circle, the diameter of which was at least twelve feet, just grazing his mate whenever he reached the lowest point of his concentric movements. Back and forth he swung at least a dozen times, looking like a tiny pendulum moving in an immense arc, and, oddly enough, the segment seemed to be perfectly formed every time. Had the bird wheeled entirely around, he would, I feel sure, have described a circle and not an ellipse. The movement was exceedingly swift, and might well have been called the embodiment of grace. Suddenly, as the diminutive acrobat reached the highest point of his arc, he dashed off to the right in a straight line, followed by his mate, and in a moment both had disappeared. Whether other observers have been witnesses of this curious gambol, I am unable to say.
Have you ever been ill-mannered enough to watch the birds going to bed? I remember spending an evening in the woods playing the role of Paul Pry on my feathered neighbors. The sun was just sinking behind the bluffs on the other side of a broad river—the Missouri—and the moon, which was half full, was hanging high in the blue sky. What were those two large black objects over yonder in the woods? My glass soon revealed their identity—a pair of turkey buzzards perched side by side on a limb, one of them squatted flat on his belly ready to take his first nap. My curiosity led me to go near them, when they spread their broad, sable wings, flew a few rods, and alighted on another horizontal bar. There they sat as long as I could see them in the thickening darkness, turning their heads now and then to see whether their ill-bred visitor was still spying upon them. They made no efforts to conceal themselves, as the small birds do in roosting, for they knew, no doubt, that nothing would carry off fowls of their size.
A little later on the same evening a whip-poor-will darted up from the roadside and flew into the woods a short distance, alighting on a white flag of good size, so that I could plainly see his dark form in the moonlight. Then I was witness of this uncanny bird's table manners, which were entirely unknown to me and may be to others. At irregular intervals he leaped into the air, now in one direction, now in another, captured an insect, and flew back to the top of the flag. Some of his evolutions were quite wonderful, and all of them were the perfection of grace. He described all kinds of curves and loops. On alighting he uttered a low, hollow chuck suggestive of the sepulchral. Another notch had to be cut in the tally-stick of my ornithological journey—I had learned how the whip-poor-will takes his nocturnal dinner of moths and beetles, and I felt that there was still such a thing as news to be gathered in birdland.
Most birds, however, do not take their dinner at night, and therefore it is easier to watch them at their table d'hote. One day a red-headed woodpecker was giving a strapping youngster as large as herself his noonday meal. She came close to him with a morsel in her long bill, and, after pounding it awhile against a limb, she thrust it into the screaming youngling's mouth. But she had failed to reduce it to a swallowable size; it stuck in his throat, and, do what he would, he could not bolt it. It was so large that he was choking; what should be done? The simplest thing you can conceive. The mother bird reached over and impatiently jerked the refractory morsel out of her baby's throat, thumped it vigorously several times against the branch, then gave it to him again, as much as to say, "Now try it! I guess you can manage it this time." And he did, for down his gullet it went with very little effort. Then she went after more provender for his spacious craw. Whenever she came with a tidbit, she would first drop it into a kind of pocket in the bark, and pound it a while to reduce it to a proper consistency; the while the youngster would sit near and watch her with hungry eyes, and often scream in his coaxing way and twinkle his wings, until she was ready to deliver up the tempting fragment.
Once, after she had given him all she had brought, he still opened his mouth and whimpered for more. At this exhibition of gluttony she lost her patience. Would he never be satisfied, the great, greedy, overgrown lubber? He was simply making a slave and a drudge of her. She looked at him for a moment with a savage glitter in her dark eyes, then began to peck him angrily right in the mouth, and drove him peremptorily backward down the limb. Mother patience has its limitations in the bird world as well as elsewhere.
On the same day a bank swallow was feeding her little ones, a half dozen or so, which were ranged on a willow stem at the margin of the river. Every time she flew toward them they set up a vigorous calling to be fed. She procured her food by skimming airily over the river and catching the insects that rose from its surface. Having nabbed one, she would dart with it to her little family, and, without alighting, and scarcely pausing in her swift flight, would thrust it into the mouth of one of the birdkins. Thus she fed them one by one until she had gone the round of the little circle, though sometimes, oddly enough, she would serve the same infant twice in succession.
The little family, all perched in a row, looked very attractive, and I was watching them closely most of the time. Suddenly the mother bird disappeared, and was gone for several minutes. I forgot to keep my eye steadily on the youngsters sitting six in a row, and, to my great surprise, when she reappeared they had left their perch, which was in plain sight, and I could not rediscover them for some time. Finally, however, I espied them cuddling among some leafy twigs a few feet away, where the mother resumed her duties of purveyor. My opinion is that she had begun to feel uneasy for their safety in the exposed place where I could see them so plainly, and so, while I was looking elsewhere, had persuaded them to shift their position. Now they were partly screened by the intervening leaves, and she felt that they were secure.
There can be no doubt that birds have a language which the youngsters soon come to understand, however simple and inarticulated it may be. In a shady hollow, one day of early spring, a pair of tufted titmice were supplying the wants of a family of famishing children, and I invited myself to the family reunion. The young birds had left the nest and were perched in a leafy tree. Most of the time they kept up a great clamor for food—or, perhaps, they shrieked merely from force of habit; but every few minutes one of the parent birds would utter a shrill, commanding cry, at which all the noisy clamorings of the youthful family would suddenly cease, and for a few moments perfect quiet would reign in titmouse town; then the hubbub would begin again, and continue until another order for perfect silence was given. So far as I could see, there was no danger from raptorial foes at hand, but the little family seemed to be in training against the approach of a marauder.
It may be a far cry, but from green-robed spring fancy yourself suddenly flung into the lap of snow-bound winter, to look upon scenes quite different from the foregoing. The Frost King had been playing a good many pranks for a week or two, and once, in a spasm of frigid ill humor, had jammed the mercury in our thermometers a dozen or more degrees below zero, and had held it there quite too long for our comfort. More than once had he shrieked and blustered and stamped his feet incontinently, and more than once sent his legions of wind, sleet, and snow howling through the leafless woods. Everybody in our central latitudes knows what an explosive old fellow the Frost King is, and how fierce and savage he can become let the mood once seize him.
Sometimes, too, by the hour he had ground his ice crystals to powder in mid-air and hurled them to the earth, covering its surface with a robe of purest white, thus proving that, with all his rudeness and bluster, he is an old gentleman of aesthetic tastes. One evening his mood became blander, and he dropped his crystals from the sky in large, damp flakes, which clung tenaciously to the branches and twigs; then during the night his breath became chilled and froze the snowy cylinders, and when morning broke the woods were a miracle of loveliness, every leaf and twig bearing a ridge of gleaming pearls, while the sylvan floor was pure white. Soon the sun was shining from an unmarred sky, and the snow-clad earth smiled back in shimmering recognition. It was a day for worship in God's first sanctuary.
Yet it was a day for watching the gambols of the birds, and such occupation by no means interfered with the spirit of worship. In the depths of the woods the white-breasted nuthatches were holding a friendly interview. How affectionately they talked to one another in idioms all their own, saying "Hick! hick!" and "Yank! yank!" and "Ha-ha! ha-ha! ha-ha!" which may mean anything that is kind and cordial and confidential. They were either playing at a game of tag, or were having a peep-show among the bushes, hiding for a moment in some leafy cluster, then dashing in pursuit of one another in the most frolicksome way. I crept in under the arches of the snow-clad bushes to watch their caperings more closely, but the birds at once quieted down, and went about their more prosaic vocation of grub gathering. They were no doubt "aching" to frisk about among the snowy bushes, but would not indulge their playful mood under the eye of a human spectator.
Presently one of them was seen carefully primping his feathers—a function that I had not previously seen a nuthatch perform. His plumes seemed to be really quite damp, and, as there was no water at hand—the streams being mailed with ice as well as nearly a half mile away—he must have used a snowbank for his lavatory. But you ask how he arranged his toilet. I had several times seen the little brown creeper clinging to the vertical wall of a tree and preening his plumes after a bath, and it was natural to suppose that his congener, the nuthatch, being also a bird of reptatory habits, would follow the same formula. But not so! Instead of clinging to the upright bole of a tree, Master Nuthatch perched crosswise on a twig like a robin or a chickadee, and smoothed his ruffled plumes.
After this interesting interview with the nuthatches, I trudged about in the woods for some time without seeing any birds. What had become of my feathered neighbors, my companions in every ramble throughout the winter? Had the storm driven them to other climes where bland winds prevailed? Oh, no! See what prudent creatures they were that wintry day. At the eastern border of the woods, where the sun shone warmly and the keen westerly breeze was broken and tempered, my little friends were found in goodly numbers, well knowing where the Frost King's anger would be softened.
Here were nuthatches and chickadees in plenty, and also tufted tits, tree sparrows, juncos, downy woodpeckers, and, to make the complement as nearly full as possible, a hairy woodpecker drummed and chir-r-r-red, several blue jays complained in the distance, and a goldfinch swinging overhead threaded the air with festoons of black and gold. And here I witnessed a new and pretty antic of a tree sparrow, which flew over from a cornfield hard by and perched on a dogwood sapling only a few feet away; then it plunged its beak into the little snowbank on the twig before it and ate greedily of the snow, some of the crystals clinging to its mandibles, just as the crumbs adhere to the lips of a hungry boy. Had the exclamation not been so much like slang, I would have cried "Next!" And there was a "next," as sure as you live, for the little bird soon flitted to another twig in the same tree and, reaching up, daintily sipped from the dripping underside of the branch just above and in front of it. Its thirst having been assuaged, it flew over into the adjoining field to resume its winter feast of seeds and berries.
And what was happening over in the field? Something worth noting, to be sure. A coterie of juncos and tree sparrows were breakfasting on the seeds of a clump of tall weeds, a few of the little feasters perched on the swaying stems, while others stood on the snow on the ground and picked the seeds from the racemes that were bent down by their burden of crystals. When I went to the place, I could see the delicate tracery of their feet on the snow, as if they had been writing their autographs on an untarnished scroll. Two tiny footprints at regular intervals, one a little before the other, and each pair connected with the next by a slender thread or two traced by the bird's claws—that is a junco's or a tree sparrow's trail in the snow.
A little later a scattering flock of tree sparrows were skipping about on the snowy floor of the woods, picking up at quick intervals a palatable tidbit. Birds often find edibles on the surface of the snow when our duller eyes can see nothing but immaculate whiteness. What long leaps the little birds took across the snow, which looked like a marble pavement with fairies dancing upon it! Near by, on one of the lower twigs of a thorn bush, a sparrow sat with feathers fluffed up and wings hanging negligently at his side, as if he were taking a siesta after a hearty meal of weed seeds and winter berries. Two of his companions soon joined him in his noonday rest, the trio making a pretty picture sitting there within an inch or two of the ground.
It was not very long before a tree sparrow perpetrated another surprise, proving that this species is not without character, as indeed no species is. He leaped to the bole of a sapling, clinging there a few moments like a chickadee or a wren, while he pecked an appetizing morsel from the bark; then he dropped down to the snow for a brief breathing spell, after which he sprang up again to the sapling for a few more bits, repeating the little performance a number of times.
In the same part of the woods a company of chickadees was flitting about in the trees, plunging into the little snowbanks on the twigs, sometimes standing in them up to their white bosoms, and often brushing a segment to the ground, thus making numerous breaches in the white drifts. The racket they made with their scolding and piping might have been called a musical din. Deciding to watch them a while, I flung myself down upon the snow. This act was the signal for a precious to-do among the nervous little potherers. Did any one ever hear or read of such a performance in all the annals of birdland? What in the world did it mean—a man lying flat on the ground out there in the woods? I was highly amused at the hurly-burly, and decided to add still more variety to it. Suddenly I sprang to my feet with a shout. Several of the birds dropped, as if shot, into a thorn bush below them, where they set up a hubbub that would have made on old-time Puritan laugh, even at the risk of being censured for levity. By and by they quieted down, and one of them began to whistle his pretty minor tune with as much serenity as if he had never been excited in his life. My winter outing proved that the Frost King and the hardy birds often go cheek by jowl, as if they were on terms of the most cordial fraternity.
ODDS AND ENDS
The ornithologist is always interested in noting how the conduct of birds of the same species differs and agrees in different localities. In a previous chapter some of the differences between the avifauna of Ohio and Kansas have been described, but a good deal still remains to be said, teaching more than one lesson in comparative ornithology.
At the beginning of my studies in the Sunflower state the song sparrows proposed an enigma for my solution, whether wittingly or unwittingly, I know not. In Ohio they were the most lavish singers in the outdoor chorus, chanting their sweet lays every month in the year, summer or winter; indeed, their most vigorous recitals were often given in February and March, when there was dearth of other bird music.
But what about the song sparrows of Kansas? The first winter and spring passed, and yet my numerous rambles in their haunts did not bring to my waiting ear one first-class song sparrow concert. A few feeble, half-hearted wisps of melody on days that were especially mild were the only vocal performances they vouchsafed. To put it bluntly and truthfully, I never, during my residence of five and a half years in Kansas, heard a first-rate song sparrow trill. Nor is that all. In the Buckeye state these birds were disposed to be sociable, often selecting their dwellings near our suburban homes, visiting our dooryards, singing their blithe roundels on the ridge of the barn roof or a post of the garden fence. Not only so, but their songs were often heard in some of the principal streets of towns where trees were abundant.
Quite otherwise was the conduct of their western cousins, which seldom came to town or even near a human residence in the country, but kept themselves ensconced in the matted copses in the banks of the Missouri River or in the deep hollows running back from the broad valley. In these sequestered haunts they were quite wary, usually scuttling out of sight at my approach. True, in Ohio many individuals also chose out-of-the-way places for habitats, but even then they were not timid, for often they would mount to the top of a bush or a sapling in plain sight and trill sweetly by the hour, with never a quaver of fear. At rare intervals a Kansas sparrow would visit the thicket on the vacant lot near my house, but, my! how shy he was! And as for singing, he would only squeak a little score.
Wondering at the reticence of the Kansas sparrows, I wrote to a friend living in Springfield, Ohio, my former home, and inquired what the song sparrows were doing in that locality. His reply was that, as usual, they had been singing with splendid effect on almost every day after the middle of February. What is the reason of this difference between the eastern and western birds? They are, according to the systematists, the same type, and yet they behave so differently. The solution of the problem is, after all, quite simple. In Kansas the song sparrows are winter residents exclusively, passing farther north when the breeding season approaches; only at rare intervals does a pair decide to remain in the state throughout the summer; whereas in the Buckeye state these birds are permanent residents, remaining throughout the year, and therefore they feel sufficiently at home to tune their lyres at all seasons. On the other hand, being only winter visitors in Kansas, they do not seem to be able to overcome their shyness; either that, or their wind harps are out of tune. As a matter of fact, migrating birds seldom sing a great deal in their winter homes, their best lyrical efforts being husbanded for their breeding haunts. I once spent part of the month of June in Minnesota, almost directly north of my Kansas field of research, and there found these charming minstrels as tuneful and affable as the most exacting bird lover could wish. Perhaps some of the very sparrows that spend the winter in silence in northeastern Kansas trill their finest arias in their summer homes on the shores of Lake Minnetonka or in the boggy hollows in the neighborhood of Duluth.
When I first began to plan for moving back to Ohio, I was foolish enough to fear that the song sparrows of that state might have changed their habits during the years of my absence, and that I should be disappointed in them: but no need of borrowing trouble on their account, for they were the same blithe and familiar birds, trilling their sweetest chansons in the trees in the residence portion of the town in which I lived. And sing! Were there ever birds with more dulcet tones, with finer voice register, or with a greater variety of tunes in their repertoire?
Going back to Kansas in winter, we note that the song sparrows, instead of remaining at one place, shifted about a good deal more than I had ever known them to do in the East. In December a pair found a dwelling in the weed clumps and brush heaps of a hollow a short distance from the Missouri River; but they soon deserted this spot, well sheltered as it was, none being seen there until the twenty-third of February. It surprised me to find another pair, and sometimes two pairs, in a thicket right on the bank of the wide river, where they were exposed to many of the winter blasts, especially those that swept down from the frozen north. Up in the deep, winding ravine they might have had excellent shelter and, so far as I could see, just as good feeding. However, I have long ago learned that there is no accounting for tastes in the bird realm any more than in the human realm.
The hardiest of the Mniotiltidae tribe are the myrtle warblers, which dapple the whitened edges of winter, both autumn and spring, with their golden rumps and amber brooches. Evidently these birds are shyer of the rigorous Ohio winters than of the more mild-mannered Kansas weather. In the former state I never saw a myrtle warbler after the first or second week in November, while in Kansas I came upon a flock of them in a wooded hollow by the river on the eighth of December, 1897, and then after a severe snowstorm had swept over the region from the western prairies. It seemed odd to find these dainty featherland blossoms when the whole country was covered with an ermine of snow.
Then they disappeared, and I did not expect to see them again until the next spring; but on the fourteenth of February, which was a warm, vernal day thrust into the midst of winter, a flock of perhaps a dozen were flitting and chirping among the trees in the suburbs of the city, their hoarse little chep, always giving one the impression that the birds have taken a cold which has affected their vocal cords, sounding as familiar as of old. However, that very evening at dusk a black cloud, charged with electricity and bellowing with anger, came up out of the west like a young Lochinvar, and hurled a fierce storm across the hills and valleys, and the next day not a myrtle warbler was to be seen in all the countryside, though I tramped weary miles in search of them. The tempest had doubtless frightened them away to the suaver southland, from which they did not return until the following spring.
One of my most pleasing observations was made on December 19, 1902. There had been a number of days of severe weather, accompanied by hard storms. Six inches of snow lay on the ground. Now the storm had spent its force, the sun was shining genially, and the snow was melting. Warm as it was, I was greatly surprised to find a flock of myrtle warblers in the woods so late in the season. They had braved the storms of the preceding week, and were as chipper and active as myrtle warblers could be. But their employment was a still greater surprise. They were darting about in the air among the treetops, as well as amid the bushes in the deep ravine, catching insects on the wing. That insects should be flying after the wintry weather of the previous week was still more surprising than that the warblers should be here to dine upon them. Soon after that day, however, the little yellow-rumps must have taken the wing route to a more genial climate, for they were seen no more that winter.
Of a more permanent character was the residence of the jolly juncos, which dwelt all winter in northeastern Kansas, let the weather be never so lowering. Always active and alert, flitting from bush to weed, and from the snow-carpeted ground to the gnarled oak saplings, now pilfering a dinner of wild berries and now a luncheon of weed seeds, they seemed to generate enough warmth in their trig little bodies to defy old Boreas to do his best. Water flowing from melting snow must be ice-cold, yet the juncos plunged into the crystal pools and rinsed their plumes with as much apparent relish as if their lavatory were tepid instead of icy, and as if balmy instead of nipping winds were blowing.
One day I watched a member of this family taking his dinner of wild grapes. Finding a dark red cluster, he would pick off the juiciest berry he could reach, press it daintily between his white mandibles for a few moments, swallow a part of the pulp, and drop the rest to the ground. What part of the grape did he eat? That is the precise problem I could not solve with certainty, for on examining the rejected portions that had been flung to the ground I found that one seed still remained, together with part of the pulp and all of the broken rind. I half suspect, though, that Master Junco likes to tipple a little—never enough, however, be it remembered, to make him reel or lose his senses. No! no! a toper Master Junco is not; he is too sane a bird for that! Would that all the citizens of our republic would display as much sound judgment and self-control.
Where all the birds sleep on biting winter nights it would be difficult to say, but the acute little juncos lease the farmer's corn shocks hard by the woods. At dusk you may startle a dozen of them from a single shock. They dart pellmell from their hiding places, chippering their protest, and when you examine the shock you find cozy nooks and ingles among the leaves and stalks, where they find couches and at the same time coverts from the sharp winds. As you stand at the border of the woods in the gloaming you can hear the rustling of the fodder as the juncos move about in their tepees, trying to find the choicest and snuggest berths. Usually they select the tops of the standing shocks, perhaps for safety; yet some may be found also in the shocks that have partly fallen to the ground. |
