They, too, may have their literatureunwritten, howeveron the dignity of labor.

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 mothers 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 journeys 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 choralists 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 enemys 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-birds nest. The king-bird swooped toward him, and alighted on his back. The next moment the two birds, the king-bird on the woodpeckers 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 woodpeckers back until he reached the other end of the meadow. I cannot be sure, but he seemed to be holding to the woodpeckers 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 dont fancy being converted into a beast of burden!
A large part of a birds 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 Lowells injunction,
Come up and feel what health there is
In the frank Dawns 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 literatureunwritten, howeveron the dignity of labor.

My high-school pupils soon learned to quarrel.

It is not to be supposed that there is a regularly graded system of instruction in the school-life of the birds. There may be method in their learning, but it would be difficult to state positively just where the primary, grammar, high-school, and college grades merge into one another, or when diplomas of efficiency are granted, if granted at all. But that there is something of a system of pedagogy among birds, and that the juniors do receive instruction from their seniors, no observer of feathered life can doubt for a moment. In the systems of human instruction the child-life of the young learner usually ends with his high-school course; he then stands at the threshold of young manhood, ready to do a good deal of wrestling with his problems on his own account. Taking that fact as our cue, we should say that the high-school instruction of the youthful bird begins when he leaves the nest, and ends when he is able to fly with dexterity, and provide for his own support, at least in the main. It is not probable that the lecture system prevails in the bird community,  or the method of class instruction now in vogue, or that books and charts and blackboards are used; but the instruction is chiefly individual, and is carried on mostly by example, coercion, and urgent appeal. There is not an inexhaustible number of branches to be pursued by the little undergraduates in plumes; but their efforts at obtaining an education consist chiefly in mastering three grand accomplishments,flying, feeding, and singing.
If ever you have seen a bevy of young red-headed woodpeckers, led by several of their elders, taking their wing-exercises, choosing a certain tree in the woods for a point of departure, and then sailing around and around with loud cries of delight, you must have concluded that it was a veritable class in calisthenics. One seldom has an opportunity to see young birds taking their first lessons in flight, but it is worth ones time and patience to be present at such a recitation. The parents set the example by flying from the nest to a perch near by, and then coax and scold their children to follow their example. If the little learners hesitate, as they usually do, their impatient teachers exclaim: Why, just try it once. You never will learn to fly any younger. If you will only spread your wings, let go of the rim of the nest, and venture out on the air, you will find that it will bear you up. Dont be afraid. But perhaps the pupils complain that it makes their heads dizzy to look down from their awful height. Then the teachers pooh-pooh at their fears, and cry condescendingly, The idea of being afraid! Why,  just see here! and they mount up into the air, poise, careen, and perform other extraordinary feats, while the youngsters gaze at them in wide-eyed wonder. At last, after much persuasion and many half-attempts, one of the youngsters spreads his pinions and flutters laboriously until he scrambles upon the nearest twig, with bated breath and throbbing pulses. He is frightened half to death, but he has found that the friendly air will support him if he makes proper use of his wings, and so he will soon make another effort, and another, until he begins really to enjoy the exercise. However, several days may elapse before the youngest and weakest member of the class can muster sufficient courage to take his first aerial journey.
Some species of birds graduate from the nest much sooner than others. In one case I observed that a family of goldfinches remained in the nest just seven days after a family of bush-sparrows, hatched on the same day, had taken their flight.[8] The yellow-billed cuckoo has given me no little surprise in this respect. When he first creeps out of his shell apartment, he is a callow, ungainly infant, black as coal, with a sparse covering of stiff bristles; but almost before a week has passed, he has hopped from his washed-out cradle to try the realities of the great world around him. Why the agile little goldfinch should remain in the crib so much longer than his less dexterous fellow-pupil,  the cuckoo, is a problem of bird school-life that I must leave for solution to wiser heads.
Having gone from the nest, the young bird has not yet learned all about the art of flying; no, indeed! He must become perfect by practice. Many a blunder will he make. At first he cannot always nicely calculate the distance to the twig that he has in view, and so he fails to give himself the proper propulsive force; he misses his footing by going too far, or not far enough, and then where he will alight is a question of what he happens to strike first. Probably a wild, desperate scramble will ensue, which ends only when the youthful novice has fallen plump upon the ground. He may be very much alarmed; but as soon as he recovers his breath, his courage rises, and he tries again.
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 phbes 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 believeif my own ears had not heard, I should be very skeptical of the accuracy of the assertionbut 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. Its mine! its 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.

Continues longer on the wing.

Nothing in Nature is more pregnant with suggestion than the nest of a bird. The story of one of these deftly woven dwellings in the woods, if fully written, might prove almost as weird and romantic as the history of a castle on the Rhine. What madrigals, what pæans, have been sung, and what victories celebrated, from the time the first fibres were braided until the chirping nestlings were able to shift for themselves! And, alas, how many fond hopes have perished as well! No doubt the ruses and subterfuges employed to elude cunning foes or ward off their murderous attacks, would fill a volume of valuable information on military tactics. One might write comedies or tragedies about the nest-life of the birds that would be no less interesting than realistic. More than that, the study of these wonderful fabrics would virtually be a study of the psychology of the feathered artisans, each nest being an index of a special type of mind and a measure of the birds mental resources. As William Hamilton Gibson has well said: To know the nidification and nest-life of a bird is to get the  cream of its history; than which nothing could be truer or more aptly expressed.
No wonder the poets have so often been thrown into lyrical moods over the homesteads of the birds! Mrs. Margaret E. Sangsters poem on The Building of the Nest is perhaps not unfamiliar to most readers; but one stanza is so graceful and rhythmical that it begs for quotation at this point:
Theyll come again to the apple-tree
Robin and all the rest
When the orchard branches are fair to see
In the snow of blossoms dressed,
And the prettiest thing in the world will be
The building of the nest.
In one of my rambles I found an abandoned towhee buntings nest containing three eggs, and could not help speculating as to the cause of its desertion. Might there have been a quarrel between husband and wife, making a separation necessary? I am loath to believe it, although, if certain acute observers are correct, divorce is not wholly unknown in the bird community. But in this case I am inclined to think that some enemy had destroyed the female, for a male flitted about in the bushes, calling a good deal and singing at intervals, and there seemed to be a plaintive note in his song, as if he might be chanting an elegy. At all events, the pair that built the nest had had their tragedy.
Every bird-student must admit that his quest for nests often ends in disappointment, because many  birds are adepts at concealment, while others build in places where you would not think of looking. However, I have had but little difficulty in finding the nests of the brown thrasher, which erects an inartistic platform of sticks, bound together by a few grass fibres, and thus is easily descried in the bushes, where it is usually placed. Early in the spring I found the nest of a pair of these birds in a thick clump of bushes near the edge of a woodland, and resolved to keep watch over it until the young family had left their home. The parent birds in this case were very solicitous for the safety of their young. Every time I called they set up a pitiful to-do, which invariably made me hurry away, after a timid peep into the cradle. There is as much difference in the temperaments of birds of the same species as there is among persons belonging to the same family. While the thrashers in question seemed to be terrified at my presence, others driven from their nests displayed little or no fear, but sat quietly on a perch near by and allowed me to examine their domicile without so much as a chirp.
The brown thrasher has surprised me by the variety of places he selects for building his log house. Wilson Flagg in his book, A Year with the Birds, says that this bird usually builds on the ground; and Mr. Eldridge E. Fish, who writes pleasantly about the birds of western New York, bears similar testimony. Perhaps thrasher-fashion in New England and New York differs from  thrasher-fashion in Ohio (in which locality the birds display the best taste I will not say); for during the spring of 1890 I found but two nests on the ground, and was surprised to find even them, while at least fifteen were discovered in other places. Most of them were on low thorn-bushes, but not all. One was built in a brush-heap, one on a pile of cord-wood, another on a small stump screened by some bushes, and two on a rail fence. Of the last two, one was partly supported by poison-ivy vines and partly by a rail; the other was built entirely on a rail in a projecting corner of the fence.
The thrasher, as has been said, builds an artless platform of sticks that in some cases barely holds together long enough to answer the purpose for which it was intended. In this respect its habits differ from those of the wood-thrush, a bird that is very abundant and musical in my neighborhood. I have found many of the wood-thrushs nests, which are built in the crotches of small saplings in the thickest part of the woods, and are made almost as substantial as the adobe dwellings of the robin. The thrush does not use as much mortar as his red-breasted relative; otherwise there is a close resemblance between the nests of the two birds.
It was amusing to find pieces of newspaper bedizening the houses of the wood-thrushes so frequently, though it cannot be said that they showed the highest literary taste in their selections; for one or two of the fragments contained  accounts of political caucuses. However, it would be too much to assume that the birds had read them, as many of us humans find such literature too deep for our comprehension. I shall neither eulogize nor stigmatize this favorite minstrel by calling him a politician, although if one were to regard his nesting-habits alone, he deserves that sobriquet quite as well as the white-eyed vireo.
That parasite among American birds, the female cow-bunting, audaciously spirits her eggs into the wood-thrushs nest, to be hatched with those that properly belong there, while she and her mate sit in the trees near by and whistle their taunting airs, and watch to see whether their dupe attends faithfully to the additional household cares imposed upon her. When the birds are hatched, the victim of this piece of imposture innocently feeds her foster children with the best tidbits she can find, spite of the fact that they may soon crowd her own offspring out of the nest-home. The wonder is that she does not discover the trick at once; for her eggs are deep blue, while the cow-birds are white, speckled with ashy brown. Can the wood-thrush be color-blind?
About two miles from town, along the banks of a small creek, was the nest of that interesting little bird, the summer warbler,a dainty structure, composed of downy material, and deftly lodged among the twigs of a sapling at the foot of a cliff. A cold spring gurgled from the rocks near by; the willows and buttonwood trees bent to the balmy breezes, and the tinkling of the brook mingled with the songs  of many birds. A place for day-dreams truly, and the summer warblers were the dryads and nymphs flitting through the realms of fancy. If all birds were as astute as the summer warbler, the race of cow-buntings would soon become extinct, or would soon have to change their methods of propagation, and go to rearing their own families. Our little strategist, when she comes home and finds a cowbirds egg dropped into her nest, begins forthwith to add another story, and thus leaves the interloper in the cellar, with a floor between it and her warm breast. It is a genuine case of being left out in the cold. I have found several of these exquisite towers that were three stories high, on the top of which the little bird sat perched like a goddess on the summit of Olympus. (My simile may seem a trifle farfetched, but I shall let it stand.) But why, you dear little sprite, do you not merely pitch the offensive egg out of the nest, instead of going to all the trouble of building a loft? No answer, save an untranslatable trill, comes from the throat of the dainty minstrel.[3]
Some years ago I witnessed a curious bit of bird-behavior that I have never seen described in any of the numerous books on ornithology which I have  consulted. I make reference to it here for the first time. I was strolling along the banks of a broad river in northern Indiana on the first of June, when a warm, steady rain set in. How the birds contrive to keep their eggs and nestlings dry during a shower had long been an enigma to me, and now was my time to find out. Knowing where a summer warbler had built her nest in some bushes, I cautiously approached, and then stood looking down on the bird before me, which showed no disposition to leave her progeny to the mercy of the elements. It was a picture indeed! The darling little motherhow can one help using an endearing term!sat with her wings and tail spread out gracefully over the rim of the nest all the way round, thus making a perfect umbrella of her lithe, dainty body.
Nothing could differ more from the airy out-door nest of the summer warbler than the dark subterranean caverns of the swallows in the bank of the creek. One day, while sauntering along a stream, I noticed a hole in the opposite bank. I passed on, but on second thought turned to look at the excavation a little more closely, when a swallow darted like an arrow into it, and in a few moments made as quick an exit. Wading across the creek, I thrust my walking-stick, which was almost four feet long, into the orifice over its entire length without reaching the end! Why a bird, so neat in attire and so agile on the wing, should build her nest in a dark Erebus like that, is a Sphinxs riddle that must be left to wiser heads to solve.

What a contrast is the open-air hammock of the Baltimore oriole, swinging from the flexible branches of a buttonwood tree a little farther up the stream! How softly the chirping brood within is rocked by the breezes that sweep down from the slopes, laden with the odor of clover blossoms! Somewhere near there must be a warbling vireos nest, for one of these birds is singing in the trees; but my eyes are not sharp enough to descry its pensile domicile.
On my way home, on the top of a hill, I step casually up to a small thorn-bush, whose branches and leaves are thickly matted together, and, as I push the foliage aside, there is a flutter of wings, followed by a rapid chirping, and a little bird flits away, pretending to be seriously wounded. It is a bush-sparrow. Cosily placed beneath the leafy roof among the thick boughs is the procreant cradle. What could be more dainty! A little nest, woven of fine grass-fibres, deftly lined with hair, and containing four speckled eggs, real gems. How beautiful for situation is this tiny cottage on the hill! Here the feathered poets may sit on their leafy verandas, look down into the green valleys, and compose verses on the pastoral attractions of Nature. One is almost tempted to spin a romance about the happy couple.
On returning, one day, from an ornithological jaunt, I met my friend, the young farmer, who knows something about my furor for the birds. There was a knowing smile on his sunburned face. I know where theres a killdeers nest, he said;  would you like to see it? Tired out as I was with my long walk, I exclaimed: Yes, sir! Ill follow you to the end of the world to see a plovers nest. The sentence was added merely by way of mild (not wild) hyperbole. A shallow pit in the open corn-field, lined with a few chips and pebbles, constituted the nest of the plover, not having so much as a spear of grass to protect it from rain and storm. It contained one egg and a callow youngster, the egg being quite large at one end and pointed at the other, which gave it a very uncouth shape. My young friend informed me that there had been five eggs when he found the nest, all lying with their acute ends toward the centre; the next time he went to look there were only four, then three, and finally only two. Evidently the parent birds were having a serious time guarding their homestead from marauders. On going to the place some days later, I found both the egg and the baby plover gone, and I could only hope that no mischance had befallen them.
Strange as it may seem, the winter is a favorable season for nest-hunting. True, the birds are not then at home, to speak with a good deal of license, or engaged in rearing families; but the deserted structures may be more readily found after the leaves have fallen from the trees and bushes. As I stroll through the woods or the marsh on a winter day, scores of nests that escaped my eye during the summer are to be seen. Especially is this the case after a snowfall, for the nests catch the descending  flakes which are piled up in them in downy mounds, and thus attract the attention of the observer. I have often felt inclined to heap upon myself the most caustic epithets for having passed again and again, during the breeding-season, so near the nest of an interesting bird without knowing of its existence until winters frosts had stripped the coppice of its leaves, and have resolved as often that the next season shall not find me napping.
In the marsh which is one of my favorite trudging-grounds, I made a quaint discovery some winters ago, which has raised more than one query in my mind. One day, after a snowfall, I found many deserted nests in the thickets. Brushing the snow out of them revealed, in the bottom of each basket, a small pile of the seeds and broken shells of wild-rose and thorn berries. Why had the birds put them thereif it was the birds? Perhaps the winter birds, when they arrived in the autumn, found these old nests good storehouses in which to lay by their winter supplies. I have never seen the birds feeding on them, but, as spring approached, the berry seeds had nearly all disappeared.
Come with me, for I know a pleasant, half-cloistered field of clover which is the habitat of a number of charming little birds. Just where it is shall remain one of my semi-sylvan secrets, for one must not betray all the confidences of ones feathered intimates. The field cuts a right angle in a woodland, by which it is, therefore, bounded on the east and north, while toward the west and south the  undulating country stretches away like a billowy sea of green. The woods themselves, on the sides adjacent to the field, are hemmed and fringed with a thick growth of saplings, bushes, and brambles, where the feathered husbands sit and hymn their joy by the hour to their little mates hugging their nests in the clover and the copse. It is a quiet spot,one of Natures nunneries. Human dwellings may be seen in the distance; but it is seldom that any one, save a mooning rambler like myself, goes there to disturb the peace of the feathered tenants.
Here, one summer a few years ago, a pair of those wary birds the yellow-breasted chats built a nest, which they placed snugly in the blackberry bushes that bordered and partly hid the rail fence. I kept close reconnoissance on this little homestead until the nascent inmates were about half-fledged, when, to my dismay, every one of them was kidnapped by some despicable nest-robber. My own sorrow was equalled only by the inexpressible anguish of the bereaved parents. To add to my troubles, a nestful of young indigo-birds came to grief in the same way. There must be, it seems, a system of brigandage in every realm, be it human or faunal.
A pair of bush-sparrows, however, were more fortunate in their brood-rearing. One day, while standing near the fence, I noticed a bush-sparrow, bearing an insect in her bill, dart down into the clover, a short distance over in the field. I walked to the spot, when she flew up with an uneasy chirp,  proclaiming a secret that she could not keep. There on the grass, sure enough, was her nestful of little ones. Some accident must have befallen the fibrous cot, for the weeds and clover were broken down and trampled flat all around it, so that it sat loosely, on the ground, without even a blade of grass to shelter it. Fearing that buccaneers in the shape of jays or hawks might rob the nest, I broke off a number of weeds and made a sort of thatched roof over it; that would also protect the panting infants from the sun, which was beating down like a furnace. Then I took my stand a few rods away, to see what the old birds would do. Erelong both the papa and mamma came with billsome morsels in their mouths, and, after fluttering about uneasily for a few minutes, darted down to the nest and fed their young. Of course, they first had to peep, and peer, and cant their dainty heads this way and that, to examine the roof I had improvised for the nest, wondering, no doubt, what kind of a bungling architect had been at work there; but finally they seemed to think all was well. Perhaps in their hearts they thanked me for my thoughtful care.
A day or two later I called again, even at the risk of coming de trop. The weeds arched over the bird crib at my former visit having withered, I made them another green roof, sheltering them as cosily as I could and leaving a small opening at the side for an entrance. After an absence of a few minutes I crept surreptitiously back to the enchanted spot,for it drew me like a loadstone,and there sat the  trim little mother on her cradle, covering her children to keep them warm, her reddish-brown tail daintily reaching out through the doorway. She did not fly up as I bent lovingly over her, and presently I stole away, desirous not to disturb her.
The bush-sparrow is a captivating little bird, graceful of form and sweet of voice, singing his cheerful trills from early spring until far past midsummer. The song makes me think of a silver thread running through a woof of golden sunshine, carried forward by a swinging shuttle of pearl. I think the figure is not far-fetched. He is quite partial to a dense little thorn-bush for a nesting-place, often concealing his grassy cottage so cunningly that you must look sharply for it among the leaves and twigs, or it will escape your eye.
One of the neatest and prettiest denizens of my clover-field was the goldfinch. Wings of black and coat of bright yellow, he went bounding through the ether, rising and falling in graceful festoons of flight, in such a lightsome way he seemed to be rocking himself on the breeze. How jauntily he wore his tiny black cap, little exquisite of the field that he is, to whom I always go hat in hand! He deserves a monograph all to himself, but at this time I can spare him only a few paragraphs.
As a rule, the goldfinches prefer to build their nests in small trees, often selecting the maples along the suburban streets of the city. I was greatly surprised, therefore, to find a nest in my clover-field, where there were no trees at all. Noticing a  bird fly into a clump of blackberry bushes one day, I took it for a female indigo-bird. A nest was soon found woven very neatly and compactly, and having not only grass-fibres wrought into its structure, but also wool and thistle-down. A queer indigo-birds nest, I mused. The wool in the cup was ruffled and loose, and taking it for a deserted homestead, I carelessly thrust my hand into it. The next moment I was sorry for the thoughtless act, for the material looked so fresh that I decided it must be an unfinished bird-cradle. I resolved to discover the owners, if possible. Two days later it was in the same condition. Had I driven away the little builders by laying defiling hands on the nest? I felt like a culprit, and waited a week before again venturing to visit the place, when, as I approached, a female goldfinch flew from the nest, uncovering five dainty white eggs, set like pearls in the bottom of the cup. A goldfinchs nest in a blackberry bush! That was a climax of surprises, in very truth.
On the same day, not far distant, another bush-sparrows nest was found in some bushes, placed about three feet from the ground. In a few weeks there were babies five in the goldfinchs nest, and four in that of the bush-sparrow. Pray keep both nests in mind, remembering that the youngsters of both families were hatched on the same day. One evening at twilight I again stepped out to the clover-field. The mother goldfinch was sitting close on her nest, and did not stir as I came near. Then I touched her lightly with my cane. Still she remained  on her nest as if glued fast, only glaring at me with her wild, beady eyes. At length I softly laid my finger on her back, when she uttered a queer, half-scolding cry, and leaped up to the nests rim, but did not fly. There she stood, turning her head and eying me keenly until I stole away, unwilling to forfeit her confidence and good-will. But when, on my way home, I paused a moment to look at the bush-sparrows nest, the mother flitted away with a frightened chirp before I came within reach. She was not as confiding as her little neighbor, the goldfinch.
Now mark! On the fifteenth of August the young bush-sparrows had become so large and well developed that when, meaning no harm, I touched them gently with my finger, they flipped out of the nest like flashes of lightning. The infant goldfinches were not yet more than half fledged, and merely snuggled close to the bottom of the nest when I caressed them. The idea of flying was still remote from their little pates. These observations prove that young bush-sparrows develop much more rapidly than young goldfinches; yet, strange as it may seem, the goldfinch, when grown, flies much higher, if not more swiftly, than his little neighbor, and continues longer on the wing.
On the same day I sat down in the clover, a few rods from the goldfinchs nest, and kept close watch on both the old birds and their offspring for an hour and a half. The sun attacked me savagely with his red-hot arrows, and the sweat broke from every  pore, but I felt amply repaid for my vigil. During the first half-hour the parent birds ventured slyly to feed their bantlings twice. Then I crept closer, and waited an hour; but the parent birds were too shy to bring their hungry nestlings a single mouthful of food, choosing, it would seem, to let them suffer hunger rather than take risk themselves. The little things were almost famished, and behaved very quaintly. Every rustle of the leaves in the wind caused them to start up, crane out their necks, pry open their mouths as wide as they could, waddle awkwardly from side to side, and chirp for something to eat. How famished they were! They even seized one anothers heads and tried to gulp one another down. The spectacle was just a little uncanny.
But, dear me! they were not as ignorant of the ways of the world as you might suppose. When I lightly tapped the stems of the bushes with my cane, instead of leaping up and opening their mouths as they were expected to do, they shrank down into the bottom of the nest, discerning at once the difference between those strokes on the bush and their parents quiet approach or loving call. Something must have put them on their guard, and instilled feelings of fear into their palpitating bosoms. Perhaps it was that shy personage, the mother herself; for she would call admonishingly at intervals from the woods, Ba-bie! ba-bie! putting a pathetic accent on the second syllable. It was droll to see  the youngsters try to preen their feathers, they went about the performance so awkwardly.
On the seventeenth of the month one of the nestlings was missing, and no amount of looking for it in the thicket revealed any clew to its whereabouts. None of the remaining birds were ready to fly. Two days later they were still in the nest, although they had grown considerably since my last visit, so that one of them was almost crowded out of the circular trundle-bed. I could not resist the temptation to lift it in my hand, just to see how pretty it was and how it would act. It uttered a sharp cry of alarm, and sprang from my hand; but its wings were still so weak that it merely fluttered in an oblique direction to the ground. The third time I caught it, it sat contentedly on my palm, and allowed me to stroke its back, looking up at its captor with mingled wonder and trustfulness.
On the heads of all the nestlings a fine down protruded up through and above the feathers. The birds looked very knowingly out of their small coal-black eyes, but the cunning little things obstinately refused to open their mouths for me, entice them as I would; however, when I moved away some distance, and their mamma came with a tempting morsel, they sprang up instantly and gulped it down. Not so very unsophisticated, after all, for mere bantlings! On the morning of the twenty-sixth all the young finches had left the nest, and were perched in the bushes near by. I contrived to catch one of them  and hold him in my hand a few moments, to admire his dainty toilet and pretty dark eyes. Thus my brief study in comparative ornithology proved that the young goldfinches left the nest seven days after the young bush-sparrows, hatched at the same time, had taken wing.
