"Hark to that petulant chirp! What ails the warbler? We called him the blue, but that was not his whole name by any means. Fancy a scientist with a new bird to label, contenting himself with one word! His whole name is—or was till lately—black-throated blue-backed warbler, or Dendroica coerulescens, and that being fairly set down for future reference for whom it may concern, I shall call him henceforth, as we did in the woods, the blue. For a day or two at first he was to us, like many another of his size, only a "wandering voice." But it was an enticing voice, a sweet-toned succession of z-z-z in ascending scale, and it was so persistent that when we really made the attempt, we had no trouble in getting sight of the little beauty hardly bigger than one's thumb. He was a wary little sprite, and though he looked down upon us as we turned opera-glasses toward him,—a battery that puts some birds into a panic,—he was not alarmed. He My fellow bird-student became fairly bewitched, and could not rest till she found his nest. For my part I gave up the warbler family long ago, as too small, too uneasy, too fond of tree-tops, to waste time and patience over. In these her native woods, my comrade led in our walks, and the moment we heard his tantalizing z-z-z she turned irresistibly toward it. I followed, of course, happy to be anywhere under these trees. One morning she tracked him inch by inch till she was fortunate enough to trace him to a wild corner in the woods given up to a tangle of fallen trees, saplings, and other growth. She went home happy, sure she was on the trail. The next day we turned our steps to that quarter and penetrated the jungle till we reached a moderately clear spot facing an impenetrable mass of low saplings. There we took our places, to wait with what patience we might for the blue. Our lucky star was in the ascendant that day, But who was she? For it is one of the difficulties about nests, that the brightly-colored male, whom one knows so well, is very sure not to show himself in the neighborhood, and his spouse is certain to look just like everybody else. However, there is always some mark by which we may know, and as soon as the watcher secured a good look she announced in an excited whisper, "We have it! a female blue, building." So it proved to be, and we planted our seats against trees for backs, and arranged ourselves to stay. The dog seeing this preparation, and recognizing it as somewhat permanent, with a heavy sigh laid himself out full length, and composed himself to sleep. The work over that nest was one of the prettiest bits of bird-life I ever watched. Never was a scrap of a warbler, a mere pinch of feathers, so perfectly delighted with anything as she with that dear little homestead of hers. It was pretty; it looked outside like the dainty hanging cradle of a vireo, but instead of being suspended from a horizontal forked twig, it was The little creature's body seemed too small to hold her joy; she simply could not bring her mind to leave it. She rushed off a short distance and brought some infinitesimal atom of something not visible to our coarse sight, but very important in hers. This she arranged carefully, then slipped into the nest and moulded it into place by pressing her breast against it and turning around. Thus she worked for some time, and then seemed to feel that her task was over, at least for the moment. Yet she could not tear herself away. She flew six inches away, then instantly came back and got into the nest, trying it this way and that. Then she ran up a stem, and in a moment down again, trying that nest in a new way, from a fresh point of view. This performance went on a long time, and we found it as impossible to leave as she did; we were as completely charmed with her ingenuous and bewitching manners as she was with her new home. Well indeed was it that we stayed that morning and enriched ourselves with the beautiful picture of bird ways, for like many another fair promise of the summer it came to naught. We had not startled her, she had not observed us at all, nor been in the least degree We were near the edge of the woods, and she was obliged to pass through part of a pasture where sheep were kept. Her one terror about her big dog was that he should take to making himself disagreeable among sheep, when she knew his days would be numbered, so she told him to stay with me. He had risen when she started, and he looked a little dubious, but sat down again, and she went away. He watched her so long as she could be seen and then turned to me for comfort. He came close and laid his big head on my lap to be petted. I patted his head and praised him a while, and then wished to be relieved. But flattery was sweet to his ears, and the touch of a hand to his brow,—he declined to be put away; on the contrary he demanded constant repetition of the agreeable sensations. If I stopped, he laid his heavy head across my arm, in a way most uncomfortable to one not accustomed to dogs. These methods not availing, he At last finding that I would not be coaxed or forced into devoting myself wholly to his entertainment, he rose with dignity, and walked off in the direction his mistress had gone, paying no more attention to my commands or my coaxings than if I did not exist. If I would not do what he wished, and pay the price of his society, he would not do what I asked. I was, therefore, left alone. I was perfectly quiet. My dress was a dull woods tint, carefully selected to be inconspicuous, and I was motionless. No little dame appeared, but I soon became aware of the pleasing sound of the blue himself. It drew nearer, and suddenly ceased. Cautiously, without moving, I looked up. My eyes fell upon the little beauty peering down upon me. I scarcely breathed while he came nearer, at last directly over my head, silent, and plainly studying me. I shall always think his conclusion was unfavorable, that he decided I was dangerous; and I, who never lay a finger on an egg or a nest in use, had to suffer for the depredations of the race to which I belong. The pretty nest so doted upon by its little builder was never We found him, indeed, so often near this particular place, a worse tangle, if possible, than the other, that we suspected they had set up their household gods here. Many times did my friend and her dog work their way through it, while I waited outside, and considered the admirable tactics of the wary warbler. The search was without result. Weeks passed, but though other birds interested us, and filled our days with pleasure, my comrade never ceased longing to find the elusive nest of that blue warbler, and our revenge came at last. Nests may be deserted, little brown spouses may be hidden under green leaves, homesteads may be so cunningly placed that one cannot find them, but baby birds cannot be concealed. They will speak for themselves; they will get out of the nest before they can fly; they will scramble about, careless of being seen; and such is the devotion of parents that they must and will follow all these vagaries, and thus give their precious secret to whoever has eyes to see. One day I came alone into the woods, and as I reached a certain place, sauntering along in perfect silence, I evidently surprised somebody, for I was saluted by low "smacks" and I caught glimpses of two birds who dived into the jewel-weed I walked slowly on up the road, for this was one of the most enchanting spots in the woods, to birds as well as to bird-lovers. Here the cuckoo hid her brood till they could fly. In this retired corner the tawny thrush built her nest, and the hermit filled its aisles with music, while on the trespass notices hung here, the yellow-bellied woodpecker drummed and signaled. It was filled with interest and with pleasant memories, and I lingered here for some time. Then as the road led me still farther away, I turned back. Coming quietly, again I surprised the blue family and was greeted in the same manner as before. They had slipped back in silence during my absence, and the young blues were, doubtless, at that moment running about under the weeds. Thus we found our warbler, the head of a family, hard at work as any sparrow, feeding a beloved, but somewhat scraggy looking, youngster, the feeble likeness of himself. There, too, we found the little brown mamma, the same, as we suppose, whose nest-building we had watched with so much interest. She also had a youngster under her charge. But Henceforth we watched with greater interest than before. Every day that we came into the woods we saw the little party of four, always near together, scrambling about under the saplings or among the jewel-weed, or running over the tangled branches of a fallen tree, the two younger calling in sharp little voices for food, and the elders bustling about on low trees to find it. We soon noticed that there was favoritism in the family. Papa fed only the little man, while mamma fed the little maid, though she too sometimes stuffed a morsel into the mouth of her son. Let us hope that by this arrangement both babies are equally fed, and not, as is often the case, the most greedy secures the greatest amount. We had now reached the last of July, and the woods were full of new voices, not alone the peeps or chirps of birdlings impatient for food. There were baffling rustles of leaves in the tree-tops, rebounds of twigs as some small form left them, flits of strange-colored wings,—migration |
