Part 12
Although the young birds have the whole world for their larder, with victuals just to their taste constantly at their elbow, they must learn even the art of eating, and, until they do so, they demand that their parents be their caterers. For several weeks after they have passed the first term of school-life, they will still sit on a limb, open their mouths, twinkle their wings, and allow their patient victuallers to thrust morsel after morsel down their throats. My opinion is that the patience of their parents wears out after a time, and they leave the overgrown youngster to paddle for himself. How proud he must be of the exploit when he catches his first insect and successfully stows it away in his maw! In a deep, quiet glen I watched a family of young phœbes and their parents catching insects on the wing. It was amusing. The old birds evidently felt that it was about time for their pupils to learn to provide their own victuals, but the youngsters stoutly demanded that their luncheons be brought them in the accustomed manner. They must have noticed that the old birds would occasionally catch an insect and dispose of it themselves. Once when the parent bird darted out for a small cabbage butterfly, a young fellow swooped down at her with such force that she let the insect squirm out of her bill and flutter to the ground, and thus make good its escape before she could recover it. Both birds lost their dinner through the greed and rashness of the little gourmand. Another time an old bird caught a yellow butterfly, dashed to a limb, and quickly gulped it down, wings and all, before any of the presumptuous high-schoolers could reach him. The bearing of the bird was most laughable. Finally, several of the young birds darted out into the air for passing insects, proving that they were taking lessons in that fine art; but their gymnastics were far from perfect, and they hit the mark scarcely half the time.
With most young birds music is a part of their high-school curriculum. Perhaps you have thought that they learn their lessons in vocal music without special instruction, but this is not always the case. Observation proves that the old birds have them under tutelage, setting them lyrical copies, which they are expected to learn by frequent rehearsal. I have myself observed such a performance in the case of the wood-pewee, as described in the chapter on “Midsummer Melodies.” First attempts are crude and awkward, although the tones may be very fine. It requires frequent drill to bring the vocal organs under perfect control, just as is the case with human singers. If you have listened to the squeaking, chattering, twittering medley of young song-sparrows, you have realized how much practice is necessary before the would-be vocalists will be able to execute the wonderful trills of which they are master when they graduate from the musical conservatory.
I must tell you of a little bird high-school class over which I once assumed charge. It consisted of three wood-thrushes, two bluebirds, and a brown thrasher, all of which were taken from the nest before they were ready to fly, and confined in a large wire cage. Very soon they learned to take food from my hand. But in many things that are essential to bird life and bird weal they had no tutors and no drill-masters, and therefore had to learn them as best they could. Yet it was surprising how soon they gained proficiency. Without a single copy from adult birds, all of them were able to fly about from perch to perch in a few days. It was not more than a week before they began to pick in an awkward way, but after more than five weeks they would still open their mouths and take food from the hand. The mechanical act of eating was something they had to learn by slow degrees. While they could readily pick up a tidbit, it seemed to be a difficult task to get it back far enough into the mouth to swallow it. This was especially true of the thrasher, whose bill was long. How he would toss a morsel about, pinch it, fling it away, catch it up again, and pound it against a perch, before he could work it back into his capacious throat!
They were amusing pets, those feathered pupils of mine. From them I have gained an insight into bird character which could have been gained in no other way. The difficulty in observing birds in the wild state is, you cannot study them at close range, and hence cannot watch their development from day to day. None the less interesting were my little pupils because they had to depend on their own wits and learn their lessons without a pedagogue. How did they learn to bathe without being shown how! They learned it, that is sure; and they went through the exercise precisely as birds do in the wildwood. They would leap into the bath-dish, duck their heads into the water, flutter their wings and tails until thoroughly rinsed, and then fly up to a perch to preen their bedrenched plumage. But they made some mirth-provoking blunders. One day a wood-thrush got astride of the rim of his bath-tub, one leg outside and the other inside, and in that interesting position tried to take his ablution. He looked exceedingly droll, and seemingly could not understand why he did not succeed better. Another time the thrasher remained outside of the bath-dish, and thrust his head over the rim into the water, squatting on the sand and twinkling his pinions. But the time came when all the birds discovered of their own accord that the proper way was to leap right into the lavatory.
How early in life do juvenile birds begin to sing? That is a question, I venture to say, that very few students of bird life would be able to answer. It may be difficult to believe—if my own ears had not heard, I should be very skeptical of the accuracy of the assertion—but my wood-thrushes had not been in my care more than three or four weeks before one of them began to twitter a little song. He could not have been much more than five weeks old. This is all the more remarkable when it is remembered that there were no adult thrushes within a half-mile of the house. He seemed to discover that he had a voice, and thought he might as well use it.
Ah, yes, and sad to relate, my high-school pupils soon learned to quarrel, and that without the example of their elders. When I threw a billsome morsel on the floor of the cage, several of them would make a dive for it, and soon get into a wrangle. “It’s mine! it’s mine!” each would proclaim by his greedy behavior. Then perhaps two would seize it, and tug at it like boys fighting for an apple. Or if one contrived to get it first, the rest would try to wrench it from his beak, and thus they would pursue one another about in a wild chase. The thrasher, being younger than his fellows, was for a time cheated out of every choice morsel he secured; but he finally learned to help himself and swallow his victuals instanter. Two of the thrushes, probably males, seemed to have a mutual grudge. They would pursue each other until the fugitive would turn and stand at bay, snapping his mandibles in a savage manner, as if they were worked by steel springs. I regret being compelled to publish these pugnacious tendencies in my beloved pets; but I prefer giving a realistic rather than a fictitious or roseate sketch of the school-days of these pupils in plumes.
IV. BIRD WORK.
“Life is real, life is earnest,” might be just as truly said of “our little brothers of the air” as of us, their big brothers of the soil. If you think that their whole career consists of nothing but play and song and bounding joy, you have seen very little of the bird life around you. For the mother bird, at least, the whole period of nesting, sometimes extending over several months, is a time of drudgery, anxiety, and, far too often, of disappointed hopes. I have heard a bird mother’s wail that went like iron into my soul, and told me all too plainly that it had come from a bereft and broken heart. When we remember how many tragedies occur in the feathered community, we scarcely care about singing, “I wish I were a little bird.” Had you witnessed the unutterable agony of a pair of yellow-breasted chats one spring, when their four pretty bairns were stolen by some heartless buccaneer, you would have thanked the Pleiades, Ursa Major, Ursa Minor, and all your other lucky stars, that you were a man or woman and not a bird.
“Oh! it would be so pleasant to fly and tilt in the air, to dash from twig to twig, to make long aerial voyages to foreign countries!” Do I hear you say that? Wait a moment. Have you ever thought that even the long, bounding flight of the swallows and swifts, accomplished apparently without effort, may sometimes become a weariness to the flesh, especially when insects are scarce and their maws empty? Then, those long nocturnal journeys that birds make during the migrating season may often tax their strength to the utmost. Indeed, if you will listen to their feeble chirping, as they sweep overhead through the darkness, you will often detect a note of fatigue running through it, as much as to say, “Ah, I wish we were at our journey’s end!” No, bird life is not all roseate. It has its humdrum and drudgery, its wear and tear, its prose as well as its poetry, its hard realism as well as its romance.
One of the tasks of bird life is the building of nests. It is true, the birds always do this work with a zest that makes it seem half play; but, after spending a day in gathering material and weaving it into the nest, scarcely taking time to stop for meals, I have no doubt the little toilers are ready to retire when bedtime comes. Have you ever watched these little artists constructing their nests? They first lay the foundation, which is usually made of rather coarse material, and is more or less loosely woven; and then they proceed to build the superstructure. Some birds, like the robin and the bluebird, will have their mouths full of material every time they come to the nest; while others, such as the dainty warblers, will return with a single fibre. Usually the bird leaps into the cup of the nest, and deftly weaves in the new material with its bill; and then shifts around with a quivering motion of body and wings, to give the structure proper shape and size. The nest must be made to fit the body of the bird like a glove, so that she may rest easily in it during the long period of incubation. The robin and the wood-thrush bring mud and clay; this they mix, no doubt, with their own saliva, which gives it its viscid character. The dainty, blue-gray gnat-catcher collects lichens of various kinds, with which she decorates the high walls of her compact little cottage. Does this tiny artist sometimes build nests just for fun or æsthetic effect? I watched the building of two nests one spring that were never used. With what a graceful touch the feathered dots laid the lichen bricks in the walls!
The hatching of the eggs must be a severe tax on the patience of the mother bird, for the principal part of this work devolves upon her. Sitting hour by hour upon the nest, looking out upon the wide spaces of air waiting to be conquered by her active wings; with nothing except hope to feed her mind; with not even a book or a newspaper to read,—well, here is a chance to let patience have her perfect work. Then think of her uneasiness at the approach of every foe. It is work; it is not mere idleness. As for her lord, it may seem only like holiday sport to sit in the tree-top and sing all the livelong day, to beguile the weary hours of his sitting mate. But perhaps it often takes on the hue of work, too, when singing becomes a duty. Small wonder, if the choralist’s vocal chords often become jaded and sore, while there may be danger of bringing on throat or lung trouble. Besides, he must often carry a dainty morsel to his spouse when he would much prefer to eat it himself. Then, he must take his turn on the nest while his partner goes off for a “constitutional” to get the stiffness out of her joints, or gathers a relay of food and preens her ruffled plumes.
One of the most unpleasant tasks of the time of incubation and brood rearing is the warding off of enemies. And they are numerous. No feathered parents can feel sure that they shall be able to tide their little family safely over this perilous period. Have you ever seen the plucky wood-pewee engaging in a contest with that highwayman in feathers, the blue jay? How he dashes at the bloodthirsty villain, snapping his mandibles viciously at every onset, and sometimes pecking a feather from his enemy’s back! Nor will he give up the battle until the jay steals off with a hangdog expression on his face. The little warbling vireo is no less game when the jay comes too near his precincts.
One day in spring I was witness to a curious incident. A red-headed woodpecker had been flying several times in and out of a hole in a tree where he (or she) had a nest. At length, when he remained within the cavity for some minutes, I stepped to the tree and rapped on the trunk with my cane. The bird bolted like a small cannon-ball from the orifice, wheeled around the tree with a swiftness that the eye could scarcely follow, and then dashed up the lane to an orchard a short distance away. But he had only leaped out of the frying-pan into the fire. In the orchard he had unconsciously got too near a king-bird’s nest. The king-bird swooped toward him, and alighted on his back. The next moment the two birds, the king-bird on the woodpecker’s back, went racing across the meadow like a streak of zigzag lightning, making a clatter that frightened every echo from its hiding-place. That gamy flycatcher actually clung to the woodpecker’s back until he reached the other end of the meadow. I cannot be sure, but he seemed to be holding to the woodpecker’s dorsal feathers with his bill. Then, bantam fellow that he was, he dashed back to the orchard with a loud chippering of exultation. “Ah, ha!” he flung across to the blushing woodpecker; “stay away the next time, if you don’t fancy being converted into a beast of burden!”
A large part of a bird’s toil, after there are children in the nest, consists in providing victuals for them. For this purpose the whole country around must be scoured, and sometimes long journeys must be made. I have watched a kingfisher flying again and again from a winding creek in the valley to her nest on a hillside nearly a half-mile distant, with a minnow in her bill, while the sun was pouring a sweltering deluge upon the fields. It kept her busy every moment to supply the imperious demands of her hungry brood in the bank. A common field-bird, which I watched one day for a long while, would often return to her nest every minute with an insect. Many, many times have I obeyed Lowell’s injunction,—
“Come up and feel what health there is In the frank Dawn’s delighted eyes, As, bending with a pitying kiss, The night-shed tears of Earth she dries.”
But even at that early hour the feathered toilers have always been ahead of the human wage-workers in beginning the labors of the day. The nestlings must have a twilight breakfast; and then, in the evening, as long as the gloaming lasts, they noisily demand just one more mouthful for supper.
Young birds are ravenous feeders. They seem to live to eat, and have no thought of eating to live. For an hour and a half, one August day, I kept watch of a nestful of bantlings, and during that time the parent birds were so shy that they fed their infants only twice. At last the little things became fairly desperate for food, springing up in the nest and opening their mouths with pitiful cries every time the breeze stirred the bushes about them. They were so famished that I hurried away lest they should go to preying on one another, for they would sometimes greedily seize one another by the bills or heads, and try to gobble one another down. Incidents like this prove that the old birds must be on the jump every moment to procure a sufficient supply of food for their young. Even after they have left the nest, the juvenile members of the family must be fed for several weeks. As long as mamma and papa will get their luncheons for them, they will make little effort to help themselves. I have seen the dainty little accentor feeding a great, overgrown mossback of a cow-bunting, which had to “juke” down to her like a giant to a dwarf to receive the morsel she offered him. What a drudgery it must have been to collect victuals enough to fill his capacious maw! Think of a toil-worn, care-fretted little mother feeding a strapping boy that will not work!
Moreover, adult birds often are kept busy for hours supplying their own craving for food. One April day a hooded warbler, natty little beau, near an old gravel-bank in the woods, was watched by me for an hour and a half. During that time he must have caught an insect almost every minute, and sometimes no sooner had he gulped down one than he made a swift dash for another. Had he not been so very, very handsome, I should have dubbed him a gourmand.
At certain seasons of the year what an active life the red-headed woodpeckers are compelled to lead, in order to satisfy the demands of their stomachs! With intervals of scarcely more than a few seconds, they bound out from a perch, seize an insect on the wing, and wheel back again. For hours this half work, half frolic is kept up. By the way, almost all birds sometimes engage in this flycatcher game of taking their prey on the wing. The Baltimore orioles, the bluebirds, the yellow-bellied woodpeckers, the crested tits, the chippies, the indigo-birds, and even the white-breasted nuthatches and English sparrows, to say nothing of many species of warblers, catch insects in this way.
Many birds have to “scratch for a living,” and that in a literal sense. There is the towhee bunting, for example. Instead of getting down on his breast, however, like the hen or the partridge, he stretches himself up on his legs as if they were stilts, and then bobs up and down in an amusing fashion, while he scatters leaves and dirt to side and rear. I do not know whether the robins scratch or not, but they often jerk the leaves from the ground with their bills, and hurl them away with a half-disdainful air. Several young wood-thrushes kept in a cage removed obstructions in the same way.
Even the merry bobolink, the Beau Brummel of our meadows and clover-fields, cannot spend every day
“Untwisting all the chains that tie The hidden soul of harmony;”
for the time comes when he must do the work of a staid husband and father, and help to take care of the growing brood. With all his pirouetting in the air, he carries in his bosom an anxious heart, as you will quickly see if you go too near his snuggery in the grass. The wild scramble in which birds of all kinds often have to engage, in order to secure a refractory insect, proves that there is ample room for the play of their best energies. Thus we see that the birds have plenty to do besides rollicking, singing, enjoying gala-days, and taking excursions to gay watering-places. Like their human brothers and sisters, they must toil patiently on “through the every-dayness of this work-day world.” They, too, may have their literature—unwritten, however—on the “dignity of labor.”
V. BIRD PLAY.
How strange it is that animals never laugh! If you watch a group of monkeys playing their antics, you will find their faces as sedate as a judge’s, save, perhaps, a merry twinkle of the eye. Comical as their gambols are, one would think they would break into convulsions of merriment. True, animals have various ways of giving vent to their exuberant feelings, but this is done very slightly by means of facial expression. Their risibles must be meagrely developed. What has been said in regard to animals in general is also true of birds, whose eyes often twinkle and are intensely expressive, but whose countenances proper reveal very little of the emotion swelling in their breasts.
Yet by the movements of their bodies you can easily read their feelings. You can tell at a glance by the conduct of a bird whether or not it is alarmed at your presence, or whether it is engaged in a frolic or in watching a wily foe. How different is the behavior of most birds in the breeding-season, with a nest near at hand, from their demeanor at other times! Look at that brown thrasher perched in a tree-top on a spring morning, singing his pæan to the surrounding woodland, and notice how fearless he appears. Contrast his manners two months later when he goes skulking through the tanglewood, afraid to be seen. Conceal their secret as they may, an expert student of birds can almost always tell if there is a nest in the neighborhood.
It is, therefore, by their conduct rather than by their facial expression that birds reveal their love of play. That they do have their frolics, no one can doubt. Much of their time is occupied in labor, and that often of the most serious, if not arduous, kind, and they frequently combine toil and play; but there are times when they seem to give themselves up to unmixed sportiveness. There is not much system in their games, so far as I have observed. They mostly engage in frolics of a rough-and-tumble kind, for the pure love of the fun, and perhaps with no thought of winning a prize.
It is possible, however, that the company of red-headed woodpeckers I watched one day in the woods were having a genuine flying-race. One tree was selected as a point of departure, from which they would start and fly around in a wide circle,—perhaps their race-track,—always returning to the same tree with loud chattering, which sounded like shouts of applause. This exercise they kept up for hours, always starting from the same tree and describing nearly the same circle. If it was not a contest of speed, I am at a loss to know what it was.
The woodpeckers, especially the youngsters, have another game that has a decidedly human flavor; it is the game of bo-peep among the trunks and branches of trees. A red-head will shy off from his companions, conceal himself somewhere behind a tree-trunk, and then peep from his hiding-place in an exquisitely comical way, until he is espied by some sharp-eyed fellow-frolicker. A vigorous chase will follow, as pursuer and pursued dash wildly away among the trees. Sometimes, when the fugitive is too hotly pursued, he will stop and keep his companion at bay by presenting his long, spearlike bill as a sort of bayonet.
Another tree-climber is the brown creeper. I have described many of his pranks in the first chapter of this volume. One November day I witnessed a performance that beats the record. Two creepers were hitching up the trunks of the trees in their characteristic manner, when one of them suddenly dropped straight down about fifteen feet, scarcely more than an inch from the trunk of the tree; then, instead of alighting, he darted straight up again the same distance, fluttered a moment uncertainly on the wing, and then dropped again to the foot of the tree, where he alighted, and resumed his upward march. But that was not all. Presently his companion, not to be outdone, began to whirl around and around the tree, descending in a spiral course until he reached the foot. There he tarried a moment to take breath, and then, much to my surprise, whirled himself up in the same way, a distance of perhaps twenty feet, accomplishing it in four or five revolutions. But, as if to distance all creepers’ pranks ever witnessed before, he descended again in the same spiral course. These performances can be interpreted only as ways in which to give vent to the spirit of frolic in the creeper nature.
