THE BROWN THRASHER

Our long-tailed thrush, or thrasher, delights in a high branch of some solitary tree, whence it will pour out its rich and intricate warble for an hour together. This bird is the great American chipper. There is no other bird that I know of that can chip with such emphasis and military decision as this yellow-eyed songster. It is like the click of a giant gunlock. Why is the thrasher so stealthy? It always seems to be going about on tip-toe. I never knew it to steal anything, and yet it skulks and hides like a fugitive from justice. One never sees it flying aloft in the air and traversing the world openly, like most birds, but it darts along fences and through bushes as if pursued by a guilty conscience. Only when the musical fit is upon it does it come up into full view, and invite the world to hear and behold.

Years pass without my finding a brown thrasher's nest; it is not a nest you are likely to stumble upon in your walk; it is hidden as a miser hides his gold, and watched as jealously. The male pours out his rich and triumphant song from the tallest tree he can find, and fairly challenges you to come and look for his treasures in his vicinity. But you will not find them if you go. The nest is somewhere on the outer circle of his song; he is never so imprudent as to take up his stand very near it. The artists who draw those cozy little pictures of a brooding mother bird, with the male perched but a yard away in full song, do not copy from nature. The thrasher's nest I found was thirty or forty rods from the point where the male was wont to indulge in his brilliant recitative. It was in an open field under a low ground-juniper. My dog disturbed the sitting bird as I was passing near. The nest could be seen only by lifting up and parting away the branches. All the arts of concealment had been carefully studied. It was the last place you would think of looking in, and, if you did look, nothing was visible but the dense green circle of the low-spreading juniper. When you approached, the bird would keep her place till you had begun to stir the branches, when she would start out, and, just skimming the ground, make a bright brown line to the near fence and bushes. I confidently expected that this nest would escape molestation, but it did not. Its discovery by myself and dog probably opened the door for ill luck, as one day, not long afterward, when I peeped in upon it, it was empty. The proud song of the male had ceased from his accustomed tree, and the pair were seen no more in that vicinity.

After a pair of nesting birds have been broken up once or twice during the season, they become almost desperate, and will make great efforts to outwit their enemies. A pair of brown thrashers built their nest in a pasture-field under a low, scrubby apple-tree which the cattle had browsed down till it spread a thick, wide mass of thorny twigs only a few inches above the ground. Some blackberry briers had also grown there, so that the screen was perfect. My dog first started the bird, as I was passing near. By stooping low and peering intently, I could make out the nest and eggs. Two or three times a week, as I passed by, I would pause to see how the nest was prospering. The mother bird would keep her place, her yellow eyes never blinking. One morning, as I looked into her tent, I found the nest empty. Some night-prowler, probably a skunk or a fox, or maybe a black snake or a red squirrel by day, had plundered it. It would seem as if it was too well screened; it was in such a spot as any depredator would be apt to explore. "Surely," he would say, "this is a likely place for a nest." The birds then moved over the hill a hundred rods or more, much nearer the house, and in some rather open bushes tried again. But again they came to grief. Then, after some delay, the mother bird made a bold stroke. She seemed to reason with herself thus: "Since I have fared so disastrously in seeking seclusion for my nest, I will now adopt the opposite tactics, and come out fairly in the open. What hides me hides my enemies: let us try greater publicity." So she came out and built her nest by a few small shoots that grew beside the path that divides the two vineyards, and where we passed to and fro many times daily. I discovered her by chance early in the morning as I proceeded to my work. She started up at my feet and flitted quickly along above the ploughed ground, almost as red as the soil. I admired her audacity. Surely no prowler by night or day would suspect a nest in this open and exposed place. There was no cover by which they could approach, and no concealment anywhere. The nest was a hasty affair, as if the birds' patience at nest-building had been about exhausted. Presently an egg appeared, and then the next day another, and on the fourth day a third. No doubt the bird would have succeeded this time had not man interfered. In cultivating the vineyards the horse and cultivator had to pass over this very spot. Upon this the bird had not calculated. I determined to assist her. I called my man, and told him there was one spot in that vineyard, no bigger than his hand, where the horse's foot must not be allowed to fall, nor tooth of cultivator to touch. Then I showed him the nest, and charged him to avoid it. Probably if I had kept the secret to myself, and let the bird run her own risk, the nest would have escaped. But the result was that the man, in elaborately trying to avoid the nest, overdid the matter; the horse plunged, and set his foot squarely upon it. Such a little spot, the chances were few that the horse's foot would fall exactly there; and yet it did, and the birds' hopes were again dashed. The pair then disappeared from my vicinity, and I saw them no more.

THE HOUSE WREN

A few years ago I put up a little bird-house in the back end of my garden for the accommodation of the wrens, and every season a pair have taken up their abode there. One spring a pair of bluebirds looked into the tenement and lingered about several days, leading me to hope that they would conclude to occupy it. But they finally went away, and later in the season the wrens appeared, and, after a little coquetting, were regularly installed in their old quarters, and were as happy as only wrens can be.

One of our younger poets, Myron Benton, saw a little bird which must have been the wren, as I know of no other bird that so throbs and palpitates with music as this little vagabond. And the pair I speak of seemed exceptionally happy, and the male had a small tornado of song in his crop that kept him "ruffled" every moment in the day. But before their honeymoon was over the bluebirds returned. I knew something was wrong before I was up in the morning. Instead of that voluble and gushing song outside the window, I heard the wrens scolding and crying at a fearful rate, and on going out saw the bluebirds in possession of the box. The poor wrens were in despair; they wrung their hands and tore their hair, after the wren fashion, but chiefly did they rattle out their disgust and wrath at the intruders. I have no doubt that, if it could have been interpreted, it would have been proven the rankest and most voluble billingsgate ever uttered. For the wren is saucy, and he has a tongue in his head that can outwag any other tongue known to me.

"Ruffled with whirlwind of his ecstasies,"

The bluebirds said nothing, but the male kept an eye on Mr. Wren, and, when he came too near, gave chase, driving him to cover under the fence, or under a rubbish-heap or other object, where the wren would scold and rattle away, while his pursuer sat on the fence or the pea-brush waiting for him to reappear.

Days passed, and the usurpers prospered and the outcasts were wretched; but the latter lingered about, watching and abusing their enemies, and hoping, no doubt, that things would take a turn, as they presently did. The outraged wrens were fully avenged. The mother bluebird had laid her full complement of eggs and was beginning to set, when one day, as her mate was perched above her on the barn, along came a boy with one of those wicked elastic slings and cut him down with a pebble. There he lay like a bit of sky fallen upon the grass. The widowed bird seemed to understand what had happened, and without much ado disappeared next day in quest of another mate.

In the mean time the wrens were beside themselves with delight; they fairly screamed with joy. If the male was before "ruffled with whirlwind of his ecstasies," he was now in danger of being rent asunder. He inflated his throat and caroled as wren never caroled before. And the female, too, how she cackled and darted about! How busy they both were! Rushing into the nest, they hustled those eggs out in less than a minute, wren time. They carried in new material, and by the third day were fairly installed again in their old quarters; but on the third day, so rapidly are these little dramas played, the female bluebird reappeared with another mate. Ah! how the wren stock went down then! What dismay and despair filled again those little breasts! It was pitiful. They did not scold as before, but after a day or two withdrew from the garden, dumb with grief, and gave up the struggle.

The chatter of a second brood of nearly fledged wrens is heard now (August 20) in an oriole's nest suspended from the branch of an apple-tree near where I write. Earlier in the season the parent birds made long and determined attempts to establish themselves in a cavity that had been occupied by a pair of bluebirds. The original proprietor of the place was the downy woodpecker. He had excavated it the autumn before, and had passed the winter there, often to my certain knowledge lying abed till nine o'clock in the morning. In the spring he went elsewhere, probably with a female, to begin the season in new quarters. The bluebirds early took possession, and in June their first brood had flown. The wrens had been hanging around, evidently with an eye on the place (such little comedies may be witnessed anywhere), and now very naturally thought it was their turn. A day or two after the young bluebirds had flown, I noticed some fine, dry grass clinging to the entrance to the cavity; a circumstance which I understood a few moments later, when the wren rushed by me into the cover of a small Norway spruce, hotly pursued by the male bluebird. It was a brown streak and a blue streak pretty close together. The wrens had gone to housecleaning, and the bluebird had returned to find his bed and bedding being pitched out of doors, and had thereupon given the wrens to understand in the most emphatic manner that he had no intention of vacating the premises so early in the season. Day after day, for more than two weeks, the male bluebird had to clear his premises of these intruders. It occupied much of his time and not a little of mine, as I sat with a book in a summer-house near by, laughing at his pretty fury and spiteful onset. On two occasions the wren rushed under the chair in which I sat, and a streak of blue lightning almost flashed in my very face. One day, just as I had passed the tree in which the cavity was located, I heard the wren scream desperately; turning, I saw the little vagabond fall into the grass with the wrathful bluebird fairly upon him; the latter had returned just in time to catch him, and was evidently bent on punishing him well. But in the squabble in the grass the wren escaped and took refuge in the friendly evergreen. The bluebird paused for a moment with outstretched wings looking for the fugitive, then flew away. A score of times during the month of June did I see the wren taxing every energy to get away from the bluebird. He would dart into the stone wall, under the floor of the summer-house, into the weeds, – anywhere to hide his diminished head. The bluebird, with his bright coat, looked like an officer in uniform in pursuit of some wicked, rusty little street gamin. Generally the favorite house of refuge of the wrens was the little spruce, into which their pursuer made no attempt to follow them. The female would sit concealed amid the branches, chattering in a scolding, fretful way, while the male with his eye upon his tormentor would perch on the topmost shoot and sing. Why he sang at such times, whether in triumph and derision, or to keep his courage up and reassure his mate, I could not make out. When his song was suddenly cut short, and I glanced to see him dart down into the spruce, my eye usually caught a twinkle of blue wings hovering near. The wrens finally gave up the fight, and their enemies reared their second brood in peace.

THE SONG SPARROW

The first song sparrow's nest I observed in the spring of 1881 was in a field under a fragment of a board, the board being raised from the ground a couple of inches by two poles. It had its full complement of eggs, and probably sent forth a brood of young birds, though as to this I cannot speak positively, as I neglected to observe it further. It was well sheltered and concealed, and was not easily come at by any of its natural enemies, save snakes and weasels. But concealment often avails little. In May, a song sparrow, which had evidently met with disaster earlier in the season, built its nest in a thick mass of woodbine against the side of my house, about fifteen feet from the ground. Perhaps it took the hint from its cousin the English sparrow. The nest was admirably placed, protected from the storms by the overhanging eaves and from all eyes by the thick screen of leaves. Only by patiently watching the suspicious bird, as she lingered near with food in her beak, did I discover its whereabouts. That brood is safe, I thought, beyond doubt. But it was not: the nest was pillaged one night, either by an owl, or else by a rat that had climbed into the vine, seeking an entrance to the house. The mother bird, after reflecting upon her ill luck about a week, seemed to resolve to try a different system of tactics, and to throw all appearances of concealment aside. She built a nest a few yards from the house, beside the drive, upon a smooth piece of greensward. There was not a weed or a shrub or anything whatever to conceal it or mark its site. The structure was completed, and incubation had begun, before I discovered what was going on. "Well, well," I said, looking down upon the bird almost at my feet, "this is going to the other extreme indeed; now the cats will have you." The desperate little bird sat there day after day, looking like a brown leaf pressed down in the short green grass. As the weather grew hot, her position became very trying. It was no longer a question of keeping the eggs warm, but of keeping them from roasting. The sun had no mercy on her, and she fairly panted in the middle of the day. In such an emergency the male robin has been known to perch above the sitting female and shade her with his outstretched wings. But in this case there was no perch for the male bird, had he been disposed to make a sunshade of himself. I thought to lend a hand in this direction myself, and so stuck a leafy twig beside the nest. This was probably an unwise interference: it guided disaster to the spot; the nest was broken up, and the mother bird was probably caught, as I never saw her afterward.

One day a tragedy was enacted a few yards from where I was sitting with a book: two song sparrows were trying to defend their nest against a black snake. The curious, interrogating note of a chicken who had suddenly come upon the scene in his walk first caused me to look up from my reading. There were the sparrows, with wings raised in a way peculiarly expressive of horror and dismay, rushing about a low clump of grass and bushes. Then, looking more closely, I saw the glistening form of the black snake, and the quick movement of his head as he tried to seize the birds. The sparrows darted about and through the grass and weeds, trying to beat the snake off. Their tails and wings were spread, and, panting with the heat and the desperate struggle, they presented a most singular spectacle. They uttered no cry, not a sound escaped them; they were plainly speechless with horror and dismay. Not once did they drop their wings, and the peculiar expression of those uplifted palms, as it were, I shall never forget. It occurred to me that perhaps here was a case of attempted bird-charming on the part of the snake, so I looked on from behind the fence. The birds charged the snake and harassed him from every side, but were evidently under no spell save that of courage in defending their nest. Every moment or two I could see the head and neck of the serpent make a sweep at the birds, when the one struck at would fall back, and the other would renew the assault from the rear. There appeared to be little danger that the snake could strike and hold one of the birds, though I trembled for them, they were so bold and approached so near to the snake's head. Time and again he sprang at them, but without success. How the poor things panted, and held up their wings appealingly! Then the snake glided off to the near fence, barely escaping the stone which I hurled at him. I found the nest rifled and deranged; whether it had contained eggs or young, I know not. The male sparrow had cheered me many a day with his song, and I blamed myself for not having rushed at once to the rescue, when the arch enemy was upon him. There is probably little truth in the popular notion that snakes charm birds. The black snake is the most subtle, alert, and devilish of our snakes, and I have never seen him have any but young, helpless birds in his mouth.

If one has always built one's nest upon the ground, and if one comes of a race of ground-builders, it is a risky experiment to build in a tree. The conditions are vastly different. One of my near neighbors, a little song sparrow, learned this lesson the past season. She grew ambitious; she departed from the traditions of her race, and placed her nest in a tree. Such a pretty spot she chose, too, – the pendent cradle formed by the interlaced sprays of two parallel branches of a Norway spruce. These branches shoot out almost horizontally; indeed, the lower ones become quite so in spring, and the side shoots with which they are clothed droop down, forming the slopes of miniature ridges; where the slopes of two branches join, a little valley is formed, which often looks more stable than it really is. My sparrow selected one of these little valleys about six feet from the ground, and quite near the walls of the house. "Here," she thought, "I will build my nest, and pass the heat of June in a miniature Norway. This tree is the fir-clad mountain, and this little vale on its side I select for my own." She carried up a great quantity of coarse grass and straws for the foundation, just as she would have done upon the ground. On the top of this mass there gradually came into shape the delicate structure of her nest, compacting and refining till its delicate carpet of hairs and threads was reached. So sly as the little bird was about it, too, – every moment on her guard lest you discover her secret! Five eggs were laid, and incubation was far advanced, when the storms and winds came. The cradle indeed did rock. The boughs did not break, but they swayed and separated as you would part your two interlocked hands. The ground of the little valley fairly gave way, the nest tilted over till its contents fell into the chasm. It was like an earthquake that destroys a hamlet.

No born tree-builder would have placed its nest in such a situation. Birds that build at the end of the branch, like the oriole, tie the nest fast; others, like the robin, build against the main trunk; still others build securely in the fork. The sparrow, in her ignorance, rested her house upon the spray of two branches, and when the tempest came, the branches parted company and the nest was engulfed.

A little bob-tailed song sparrow built her nest in a pile of dry brush very near the kitchen door of a farmhouse on the skirts of the northern Catskills, where I was passing the summer. It was late in July, and she had doubtless reared one brood in the earlier season. Her toilet was decidedly the worse for wear. I noted her day after day, very busy about the fence and quince bushes between the house and milk house, with her beak full of coarse straw and hay. To a casual observer, she seemed flitting about aimlessly, carrying straws from place to place just to amuse herself. When I came to watch her closely to learn the place of her nest, she seemed to suspect my intention, and made many little feints and movements calculated to put me off my track. But I would not be misled, and presently had her secret. The male did not assist her at all, but sang much of the time in an apple-tree or upon the fence, on the other side of the house.

The song sparrow nearly always builds upon the ground, but my little neighbor laid the foundations of her domicile a foot or more above the soil. And what a mass of straws and twigs she did collect together! How coarse and careless and aimless at first, – a mere lot of rubbish dropped upon the tangle of dry limbs; but presently how it began to refine and come into shape in the centre! till there was the most exquisite hair-lined cup set about by a chaos of coarse straws and branches. What a process of evolution! The completed nest was foreshadowed by the first stiff straw; but how far off is yet that dainty casket with its complement of speckled eggs! The nest was so placed that it had for canopy a large, broad, drooping leaf of yellow dock. This formed a perfect shield against both sun and rain, while it served to conceal it from any curious eyes from above, – from the cat, for instance, prowling along the top of the wall. Before the eggs had hatched, the docken leaf wilted and dried and fell down upon the nest. But the mother bird managed to insinuate herself beneath it, and went on with her brooding all the same.

Then I arranged an artificial cover of leaves and branches, which shielded her charge till they had flown away. A mere trifle was this little bob-tailed bird with her arts and her secrets, and the male with his song, and yet the pair gave a touch of something to those days and to that place which I would not willingly have missed.
