THE WOOD THRUSH

The wood thrush is the handsomest species of the thrush family. In grace and elegance of manner he has no equal. Such a gentle, high-bred air, and such inimitable ease and composure in his flight and movement! He is a poet in very word and deed. His carriage is music to the eye. His performance of the commonest act, as catching a beetle, or picking a worm from the mud, pleases like a stroke of wit or eloquence. Was he a prince in the olden time, and do the regal grace and mien still adhere to him in his transformation? What a finely proportioned form! How plain, yet rich, his color, – the bright russet of his back, the clear white of his breast, with the distinct heart-shaped spots! It may be objected to Robin that he is noisy and demonstrative; he hurries away or rises to a branch with an angry note, and flirts his wings in ill-bred suspicion. The thrasher, or red thrush, sneaks and skulks like a culprit, hiding in the densest alders; the catbird is a coquette and a flirt, as well as a sort of female Paul Pry; and the chewink shows his inhospitality by espying your movements like a detective. The wood thrush has none of these underbred traits. He regards me unsuspiciously, or avoids me with a noble reserve – or, if I am quiet and incurious, graciously hops toward me, as if to pay his respects, or to make my acquaintance. I have passed under his nest within a few feet of his mate and brood, when he sat near by on a branch eying me sharply, but without opening his beak; but the moment I raised my hand toward his defenseless household his anger and indignation were beautiful to behold.

What a noble pride he has! Late one October, after his mates and companions had long since gone South, I noticed one for several successive days in the dense part of this next-door wood, flitting noiselessly about, very grave and silent, as if doing penance for some violation of the code of honor. By many gentle, indirect approaches, I perceived that part of his tail-feathers were undeveloped. The sylvan prince could not think of returning to court in this plight, and so, amid the falling leaves and cold rains of autumn, was patiently biding his time.

It is a curious habit the wood thrush has of starting its nest with a fragment of newspaper or other paper. Except in remote woods, I think it nearly always puts a piece of paper in the foundation of its nest. Last spring I chanced to be sitting near a tree in which a wood thrush had concluded to build. She came with a piece of paper nearly as large as my hand, placed it upon the branch, stood upon it a moment, and then flew down to the ground. A little puff of wind caused the paper to leave the branch a moment afterward. The thrush watched it eddy slowly down to the ground, when she seized it and carried it back. She placed it in position as before, stood upon it again for a moment, and then flew away. Again the paper left the branch, and sailed away slowly to the ground. The bird seized it again, jerking it about rather spitefully, I thought; she turned it round two or three times, then labored back to the branch with it, upon which she shifted it about as if to hit upon some position in which it would lie more securely. This time she sat down upon it for a moment, and then went away, doubtless with the thought in her head that she would bring something to hold it down. The perverse paper followed her in a few seconds. She seized it again, and hustled it about more than before. As she rose with it toward the nest, it in some way impeded her flight, and she was compelled to return to the ground with it. But she kept her temper remarkably well. She turned the paper over and took it up in her beak several times before she was satisfied with her hold, and then carried it back to the branch, where, however, it would not stay. I saw her make six trials of it, when I was called away. I think she finally abandoned the restless fragment, probably a scrap that held some "breezy" piece of writing, for later in the season I examined the nest and found no paper in it.

How completely the life of a bird revolves about its nest, its home! In the case of the wood thrush, its life and joy seem to mount higher and higher as the nest prospers. The male becomes a fountain of melody; his happiness waxes day by day; he makes little triumphal tours about the neighborhood, and pours out his pride and gladness in the ears of all. How sweet, how well-bred, is his demonstration! But let any accident befall that precious nest, and what a sudden silence falls upon him! Last summer a pair of wood thrushes built their nest within a few rods of my house, and when the enterprise was fairly launched and the mother bird was sitting upon her four blue eggs, the male was in the height of his song. How he poured forth his rich melody, never in the immediate vicinity of the nest, but always within easy hearing distance! Every morning, as promptly as the morning came, between five and six, he would sing for half an hour from the top of a locust-tree that shaded my roof. I came to expect him as much as I expected my breakfast, and I was not disappointed till one morning I seemed to miss something. What was it? Oh, the thrush had not sung this morning. Something is the matter; and, recollecting that yesterday I had seen a red squirrel in the trees not far from the nest, I at once inferred that the nest had been harried. Going to the spot, I found my fears were well grounded; every egg was gone. The joy of the thrush was laid low. No more songs from the tree-top, and no more songs from any point, till nearly a week had elapsed, when I heard him again under the hill, where the pair had started a new nest, cautiously tuning up, and apparently with his recent bitter experience still weighing upon him.

There is no nest-builder that suffers more from crows and squirrels and other enemies than the wood thrush. It builds as openly and unsuspiciously as if it thought all the world as honest as itself. Its favorite place is the fork of a sapling, eight or ten feet from the ground, where it falls an easy prey to every nest-robber that comes prowling through the woods and groves. It is not a bird that skulks and hides, like the catbird, the brown thrasher, the chat, or the chewink, and its nest is not concealed with the same art as theirs. Our thrushes are all frank, open-mannered birds; but the veery and the hermit build on the ground, where they may at least escape the crows, owls, and jays, and stand a good chance of being overlooked by the red squirrel and weasel also; while the robin seeks the protection of dwellings and outbuildings. For years I have not known the nest of a wood thrush to succeed. During the season referred to I observed but two, both apparently a second attempt, as the season was well advanced, and both failures. In one case, the nest was placed in a branch that an apple-tree, standing near a dwelling, held out over the highway. The structure was barely ten feet above the middle of the road, and would just escape a passing load of hay. It was made conspicuous by the use of a large fragment of newspaper in its foundation, – an unsafe material to build upon in most cases. Whatever else the press may guard, this particular newspaper did not guard this nest from harm. It saw the egg and probably the chick, but not the fledgeling. A murderous deed was committed above the public highway, but whether in the open day or under cover of darkness I have no means of knowing. The frisky red squirrel was doubtless the culprit. The other nest was in a maple sapling, within a few yards of the little rustic summer-house already referred to. The first attempt of the season, I suspect, had failed in a more secluded place under the hill; so the pair had come up nearer the house for protection. The male sang in the trees near by for several days before I chanced to see the nest. The very morning, I think, it was finished, I saw a red squirrel exploring a tree but a few yards away; he probably knew what the singing meant as well as I did. I did not see the inside of the nest, for it was almost instantly deserted, the female having probably laid a single egg, which the squirrel had devoured.

One evening, while seated upon my porch, I had convincing proof that musical or song contests do take place among the birds. Two wood thrushes who had nests near by sat on the top of a dead tree and pitted themselves against each other in song for over half an hour, contending like champions in a game, and certainly affording the rarest treat in wood-thrush melody I had ever had. They sang and sang with unwearied spirit and persistence, now and then changing position or facing in another direction, but keeping within a few feet of each other. The rivalry became so obvious and was so interesting that I finally made it a point not to take my eyes from the singers. The twilight deepened till their forms began to grow dim; then one of the birds could stand the strain no longer, the limit of fair competition had been reached, and seeming to say, "I will silence you, anyhow," it made a spiteful dive at its rival, and in hot pursuit the two disappeared in the bushes beneath the tree.

THE BALTIMORE ORIOLE

The nest of nests, the ideal nest, is unquestionably that of the Baltimore oriole. It is the only perfectly pensile nest we have. The nest of the orchard oriole is indeed mainly so, but this bird generally builds lower and shallower, more after the manner of the vireos.

The Baltimore oriole loves to attach its nest to the swaying branches of the tallest elms, making no attempt at concealment, but satisfied if the position be high and the branch pendent. This nest would seem to cost more time and skill than any other bird structure. A peculiar flax-like material seems to be always sought after and always found. The nest when completed assumes the form of a large, suspended gourd. The walls are thin but firm, and proof against the most driving rain. The mouth is hemmed or over-handed with strings or horsehair, and the sides are usually sewed through and through with the same.

Not particular as to the matter of secrecy, the bird is not particular as to material, so that it be of the nature of strings or threads. A lady friend once told me that, while she was working by an open window, one of these birds approached while her back was turned, and, seizing a skein of some kind of thread or yarn, made off with it to its half-finished nest. But the perverse yarn caught fast in the branches, and, in the bird's efforts to extricate it, got hopelessly tangled. She tugged away at it all day, but was finally obliged to content herself with a few detached portions. The fluttering strings were an eyesore to her ever after, and, passing and repassing, she would give them a spiteful jerk, as much as to say, "There is that confounded yarn that gave me so much trouble."

One day in Kentucky I saw an oriole weave into her nest unusual material. As we sat upon the lawn in front of the cottage, we had noticed the bird just beginning her structure, suspending it from a long, low branch of the Kentucky coffee-tree that grew but a few feet away. I suggested to my host that if he would take some brilliant yarn and scatter it about upon the shrubbery, the fence, and the walks, the bird would probably avail herself of it, and weave a novel nest. I had heard of its being done, but had never tried it myself. The suggestion was at once acted upon, and in a few moments a handful of zephyr yarn, crimson, orange, green, yellow, and blue, was distributed about the grounds. As we sat at dinner a few moments later, I saw the eager bird flying up toward her nest with one of these brilliant yarns streaming behind her. They had caught her eye at once, and she fell to work upon them with a will; not a bit daunted by their brilliant color, she soon had a crimson spot there amid the green leaves. She afforded us rare amusement all the afternoon and the next morning. How she seemed to congratulate herself over her rare find! How vigorously she knotted those strings to her branch and gathered the ends in and sewed them through and through the structure, jerking them spitefully like a housewife burdened with many cares! How savagely she would fly at her neighbor, an oriole that had a nest just over the fence a few yards away, when she invaded her territory! The male looked on approvingly, but did not offer to lend a hand. There is something in the manner of the female on such occasions, something so decisive and emphatic, that one entirely approves of the course of the male in not meddling or offering any suggestions. It is the wife's enterprise, and she evidently knows her own mind so well that the husband keeps aloof, or plays the part of an approving spectator.

The woolen yarn was ill-suited to the Kentucky climate. This fact the bird seemed to appreciate, for she used it only in the upper part of her nest, in attaching it to the branch and in binding and compacting the rim, making the sides and bottom of hemp, leaving it thin and airy, much more so than are the same nests with us. No other bird would, perhaps, have used such brilliant material; their instincts of concealment would have revolted, but the oriole aims more to make its nest inaccessible than to hide it. Its position and depth insure its safety.

THE WHIP-POOR-WILL

One day in May, walking in the woods, I came upon the nest of a whip-poor-will, or rather its eggs, for it builds no nest, – two elliptical whitish spotted eggs lying upon the dry leaves. My foot was within a yard of the mother bird before she flew. I wondered what a sharp eye would detect curious or characteristic in the ways of the bird, so I came to the place many times and had a look. It was always a task to separate the bird from her surroundings, though I stood within a few feet of her, and knew exactly where to look. One had to bear on with his eye, as it were, and refuse to be baffled. The sticks and leaves, and bits of black or dark-brown bark, were all exactly copied in the bird's plumage. And then she did sit so close, and simulate so well a shapeless, decaying piece of wood or bark! Twice I brought a companion, and, guiding his eye to the spot, noted how difficult it was for him to make out there, in full view upon the dry leaves, any semblance to a bird. When the bird returned after being disturbed, she would alight within a few inches of her eggs, and then, after a moment's pause, hobble awkwardly upon them.

After the young had appeared, all the wit of the bird came into play. I was on hand the next day, I think. The mother bird sprang up when I was within a pace of her, and in doing so fanned the leaves with her wings till they sprang up, too; as the leaves started the young started, and as they were of the same color, to tell which was the leaf and which the bird was a trying task to any eye. I came the next day, when the same tactics were repeated. Once a leaf fell upon one of the young birds and nearly hid it. The young are covered with a reddish down, like a young partridge, and soon follow their mother about. When disturbed, they gave but one leap, then settled down, perfectly motionless and stupid, with eyes closed. The parent bird, on these occasions, made frantic efforts to decoy me away from her young. She would fly a few paces and fall upon her breast, and a spasm, like that of death, would run through her tremulous outstretched wings and prostrate body. She kept a sharp eye out the mean while to see if the ruse took, and, if it did not, she was quickly cured, and, moving about to some other point, tried to draw my attention as before. When followed she always alighted upon the ground, dropping down in a sudden, peculiar way. The second or third day both old and young had disappeared.

The whip-poor-will walks as awkwardly as a swallow, which is as awkward as a man in a bag, and yet she manages to lead her young about the woods. The latter, I think, move by leaps and sudden spurts, their protective coloring shielding them most effectively.

As the shadows deepen and the stars begin to come out, the whip-poor-will suddenly strikes up. What a rude intrusion upon the serenity and harmony of the hour! A cry without music, insistent, reiterated, loud, penetrating, and yet the ear welcomes it; the night and the solitude are so vast that they can stand it; and when, an hour later, as the night enters into full possession, the bird comes and serenades me under my window or upon my doorstep, my heart warms toward it. Its cry is a love-call, and there is something of the ardor and persistence of love in it, and when the female responds, and comes and hovers near, there is an interchange of subdued, caressing tones between the two birds that it is a delight to hear. During my first summer in my cabin one bird used to strike up every night from a high ledge of rocks in front of my door. At just such a moment in the twilight he would begin, the first to break the stillness. Then the others would follow, till the solitude was vocal with their calls. They are rarely heard later than ten o'clock. Then at daybreak they take up the tale again, whipping poor Will till one pities him. One April morning between three and four o'clock, hearing one strike up near my window, I began counting its calls. My neighbor had told me he had heard one call over two hundred times without a break, which seemed to me a big story. But I have a much bigger one to tell. This bird actually laid upon the back of poor Will one thousand and eighty-eight blows, with only a barely perceptible pause here and there, as if to catch its breath. Then it stopped about half a minute and began again, uttering this time three hundred and ninety calls, when it paused, flew a little farther away, took up the tale once more, and continued till I fell asleep.

By day the whip-poor-will apparently sits motionless upon the ground. A few times in my walks through the woods I have started one up from almost under my feet. On such occasions the bird's movements suggest those of a bat; its wings make no noise, and it wavers about in an uncertain manner, and quickly drops to the ground again. One June day we flushed an old one with her two young, but there was no indecision or hesitation in the manner of the mother bird this time. The young were more than half fledged, and they scampered away a few yards and suddenly squatted upon the ground, where their assimilative coloring rendered them almost invisible. Then the anxious parent put forth all her arts to absorb our attention and lure us away from her offspring. She flitted before us from side to side, with spread wings and tail, now falling upon the ground, where she would remain a moment as if quite disabled, then perching upon an old stump or low branch with drooping, quivering wings, and imploring us by every gesture to take her and spare her young. My companion had his camera with him, but the bird would not remain long enough in one position for him to get her picture.

THE BLACK-THROATED BLUE WARBLER A SEARCH FOR A RARE NEST

I had set out in hopes of finding a rare nest, – the nest of the black-throated blue-backed warbler, which, it seemed, with one or two others, was still wanting to make the history of our warblers complete. The woods were extensive, and full of deep, dark tangles, and looking for any particular nest seemed about as hopeless a task as searching for a needle in a haystack, as the old saying is. Where to begin, and how? But the principle is the same as in looking for a hen's nest, – first find your bird, then watch its movements.

The bird is in these woods, for I have seen him scores of times, but whether he builds high or low, on the ground or in the trees, is all unknown to me. That is his song now, – "twe-twea-twe-e-e-a," with a peculiar summer languor and plaintiveness, and issuing from the lower branches and growths. Presently we – for I have been joined by a companion – discover the bird, a male, insecting in the top of a newly fallen hemlock. The black, white, and blue of his uniform are seen at a glance. His movements are quite slow compared with some of the warblers. If he will only betray the locality of that little domicile where his plainly clad mate is evidently sitting, it is all we will ask of him. But this he seems in no wise disposed to do. Here and there, and up and down, we follow him, often losing him, and as often refinding him by his song; but the clew to his nest, how shall we get it? Does he never go home to see how things are getting on, or to see if his presence is not needed, or to take madam a morsel of food? No doubt he keeps within earshot, and a cry of distress or alarm from the mother bird would bring him to the spot in an instant. Would that some evil fate would make her cry, then! Presently he encounters a rival. His feeding-ground infringes upon that of another, and the two birds regard each other threateningly. This is a good sign, for their nests are evidently near.

Their battle-cry is a low, peculiar chirp, not very fierce, but bantering and confident. They quickly come to blows, but it is a very fantastic battle, and, as it would seem, indulged in more to satisfy their sense of honor than to hurt each other, for neither party gets the better of the other, and they separate a few paces and sing, and squeak, and challenge each other in a very happy frame of mind. The gauntlet is no sooner thrown down than it is again taken up by one or the other, and in the course of fifteen or twenty minutes they have three or four encounters, separating a little, then provoked to return again like two cocks, till finally they withdraw beyond hearing of each other, – both, no doubt, claiming the victory. But the secret of the nest is still kept. Once I think I have it. I catch a glimpse of a bird which looks like the female, and near by, in a small hemlock about eight feet from the ground, my eye detects a nest. But as I come up under it, I can see daylight through it, and that it is empty, – evidently only partly finished, not lined or padded yet. Now if the bird will only return and claim it, the point will be gained. But we wait and watch in vain. The architect has knocked off to-day, and we must come again, or continue our search.

Despairing of finding either of the nests of the two males, we pushed on through the woods to try our luck elsewhere. Before long, just as we were about to plunge down a hill into a dense, swampy part of the woods, we discovered a pair of the birds we were in quest of. They had food in their beaks, and, as we paused, showed great signs of alarm, indicating that the nest was in the immediate vicinity. This was enough. We would pause here and find this nest, anyhow. To make a sure thing of it, we determined to watch the parent birds till we had wrung from them their secret. So we doggedly crouched down and watched them, and they watched us. It was diamond cut diamond. But as we felt constrained in our movements, desiring, if possible, to keep so quiet that the birds would, after a while, see in us only two harmless stumps or prostrate logs, we had much the worst of it. The mosquitoes were quite taken with our quiet, and knew us from logs and stumps in a moment. Neither were the birds deceived, not even when we tried the Indian's tactics, and plumed ourselves with green branches. Ah, the suspicious creatures, how they watched us with the food in their beaks, abstaining for one whole hour from ministering to that precious charge which otherwise would have been visited every few moments! Quite near us they would come at times, between us and the nest, eying us so sharply. Then they would move off, and apparently try to forget our presence. Was it to deceive us, or to persuade himself and his mate that there was no serious cause for alarm, that the male would now and then strike up in full song and move off to some distance through the trees? But the mother bird did not allow herself to lose sight of us at all, and both birds, after carrying the food in their beaks a long time, would swallow it themselves. Then they would obtain another morsel and apparently approach very near the nest, when their caution or prudence would come to their aid, and they would swallow the food and hasten away. I thought the young birds would cry out, but not a syllable from them. Yet this was, no doubt, what kept the parent birds away from the nest. The clamor the young would have set up on the approach of the old with food would have exposed everything.

After a time I felt sure I knew within a few feet where the nest was concealed. Indeed, I thought I knew the identical bush. Then the birds approached each other again and grew very confidential about another locality some rods below. This puzzled us, and, seeing the whole afternoon might be spent in this manner and the mystery unsolved, we determined to change our tactics and institute a thorough search of the locality. This procedure soon brought things to a crisis, for, as my companion clambered over a log by a little hemlock, a few yards from where we had been sitting, with a cry of alarm out sprang the young birds from their nest in the hemlock, and, scampering and fluttering over the leaves, disappeared in different directions. Instantly the parent birds were on the scene in an agony of alarm. Their distress was pitiful. They threw themselves on the ground at our very feet, and fluttered, and cried, and trailed themselves before us, to draw us away from the place, or distract our attention from the helpless young. I shall not forget the male bird, how bright he looked, how sharp the contrast as he trailed his painted plumage there on the dry leaves. Apparently he was seriously disabled. He would start up as if exerting every muscle to fly away, but no use; down he would come, with a helpless, fluttering motion, before he had gone two yards, and apparently you had only to go and pick him up. But before you could pick him up, he had recovered somewhat and flown a little farther; and thus, if you were tempted to follow him, you would soon find yourself some distance from the scene of the nest, and both old and young well out of your reach. The female bird was not less solicitous, and practiced the same arts upon us to decoy us away, but her dull plumage rendered her less noticeable. The male was clad in holiday attire, but his mate in an every-day working-garb.

The nest was built in the fork of a little hemlock, about fifteen inches from the ground, and was a thick, firm structure, composed of the finer material of the woods, with a lining of very delicate roots or rootlets. There were four young birds and one addled egg.
