One of these noisy fellows served me an excellent turn. It was the last day of my visit, and I had just taken my farewell look at the enchanting prospect from the summit, when I heard the lisp of a brown creeper. This was the first of his kind that I had seen here, and I stopped immediately to watch him, in hopes he would sing. Creeper-like he tried one tree after another in quick succession, till at last, while he was exploring a dead spruce which had toppled half-way to the ground, a hawk screamed loudly overhead. Instantly the little creature flattened himself against the trunk, spreading his wings to their very utmost and ducking his head until, though I had been all the while eying his motions through a glass at the distance of only a few rods, it was almost impossible to believe that yonder tiny brown fleck upon the bark was really a bird and not a lichen. He remained in this posture for perhaps a minute, only putting up his head two or three times to peer cautiously round. Unless I misjudged him, he did not discriminate between the screech of the hawk and the ank, ank of a nuthatch, which followed it; and this, with an indefinable something in his manner, made me suspect him of being a young bird. Young or old, however, he had learned one lesson well, at all events, one which I hoped would keep him out of the talons of his enemies for long days to come.
It was pleasant to see how cheerfully he resumed work as soon as the alarm was over. This danger was escaped, at any rate; and why should he make himself miserable with worrying about the next? He had the true philosophy. We who pity the birds for their numberless perils are ourselves in no better case. Consumption, fevers, accidents, enemies of every name are continually lying in wait for our destruction. We walk surrounded with them; seeing them not, to be sure, but knowing, all the same, that they are there; yet feeling, too, like the birds, that in some way or other we shall elude them a while longer, and holding at second hand the truth which these humble creatures practice upon instinctively,—"Sufficient unto the day is the evil thereof."
Not far from this spot, on a previous occasion, I had very unexpectedly come face to face with another of the creeper's blood-thirsty persecutors. It happened that a warbler was singing in a lofty birch, and being in doubt about the song (which was a little like the Nashville's, but longer in each of its two parts and ending with a less confused flourish), I was of course very desirous to see the singer. But to catch sight of a small bird amid thick foliage, fifty feet or more above you, is not an easy matter, as I believe I have already once remarked. So when I grew weary of the attempt, I bethought myself to try the efficacy of an old device, well known to all collectors, and proceeded to imitate, as well as I could, the cries of some bird in distress. My warbler was imperturbable. He had no nest or young to be anxious about, and kept on singing. But pretty soon I was apprised of something in the air, coming toward me, and looking up, beheld a large owl who appeared to be dropping straight upon my head. He saw me in time to avoid such a catastrophe, however, and, describing a graceful curve, alighted on a low branch near by, and stared at me as only an owl can. Then away he went, while at the same instant a jay dashed into the thicket and out again, shouting derisively, "I saw you! I saw you!" Evidently the trick was a good one, and moderately well played; in further confirmation of which the owl hooted twice in response to some peculiarly happy efforts on my part, and then actually came back again for another look. This proved sufficient, and he quickly disappeared; retiring to his leafy covert or hollow tree, to meditate, no doubt, on the strange creature whose unseasonable noises had disturbed his afternoon slumbers. Likely enough he could not readily fall asleep again for wondering how I could possibly find my way through the woods in the darkness of daylight. So difficult is it, we may suppose, for even an owl to put himself in another's place and see with another's eyes.
This little episode over, I turned again to the birch-tree, and fortunately the warbler's throat was of too fiery a color to remain long concealed; though it was at once a pleasure and an annoyance to find myself still unacquainted with at least one song out of the Blackburnian's repertory. In times past I had carefully attended to his music, and within only a few days, in the White Mountain Notch, I had taken note of two of its variations; but here was still another, which neither began with zillup, zillup, nor ended with zip, zip,—notes which I had come to look upon as the Blackburnian's sign-vocal. Yet it must have been my fault, not his, that I failed to recognize him; for every bird's voice has something characteristic about it, just as every human voice has tones and inflections which those who are sufficiently familiar with its owner will infallibly detect. The ear feels them, although words cannot describe them. Articulate speech is but a modern invention, as it were, in comparison with the five senses; and since practice makes perfect, it is natural enough that every one of the five should easily, and as a matter of course, perceive shades of difference so slight that language, in its present rudimentary state, cannot begin to take account of them.
The other warblers at Owl's Head, as far as they came under my notice, were the black-and-white creeper, the blue yellow-backed warbler, the Nashville, the black-throated green, the black-throated blue, the yellow-rumped, the chestnut-sided, the oven-bird (already spoken of), the small-billed water thrush, the Maryland yellow-throat, the Canadian flycatcher, and the redstart.
The water thrush (I saw only one individual) was by the lake-side, and within a rod or two of the bowling alley. What a strange, composite creature he is! thrush, warbler, and sandpiper all in one; with such a bare-footed, bare-legged appearance, too, as if he must always be ready to wade; and such a Saint Vitus's dance! His must be a curious history. In particular, I should like to know the origin of his teetering habit, which seems to put him among the beach birds. Can it be that such frequenters of shallow water are rendered less conspicuous by this wave-like, up-and-down motion, and have actually adopted it as a means of defense, just as they and many more have taken on a color harmonizing with that of their ordinary surroundings?[27]
The black-throated blue warblers were common, and like most of their tribe were waiting upon offspring just out of the nest. I watched one as he offered his charge a rather large insect. The awkward fledgeling let it fall three times; and still the parent picked it up again, only chirping mildly, as if to say, "Come, come, my beauty, don't be quite so bungling." But even in the midst of their family cares, they still found leisure for music; and as they and the black-throated greens were often singing together, I had excellent opportunities to compare the songs of the two species. The voices, while both very peculiar, are at the same time so nearly alike that it was impossible for me on hearing the first note of either strain to tell whose it was. With the voice the similarity ends, however; for the organ does not make the singer, and while the blue seldom attempts more than a harsh, monotonous kree, kree, kree, the green possesses the true lyrical gift, so that few of our birds have a more engaging song than his simple Trees, trees, murmuring trees, or if you choose to understand it so, Sleep, sleep, pretty one, sleep.[28]
I saw little of the blue yellow-backed warbler, but whenever I took the mountain path I was certain to hear his whimsical upward-running song, broken off at the end with a smart snap. He seemed to have chosen the neighborhood of the fernery for his peculiar haunt, a piece of good taste quite in accord with his general character. Nothing could well be more beautiful than this bird's plumage; and his nest, which is "globular, with an entrance on one side," is described as a wonder of elegance; while in grace of movement not even the titmouse can surpass him. Strange that such an exquisite should have so fantastic a song.
I have spoken of the rainy weather. There were times when the piazza was as far out-of-doors as it was expedient to venture. But even then I was not without excellent feathered society. Red-eyed vireos (one pair had their nest within twenty feet of the hotel), chippers, song sparrows, snow-birds, robins, waxwings, and phœbes were to be seen almost any moment, while the hermit thrushes, as I have before mentioned, paid us occasional visits. The most familiar of our door-yard friends, however, to my surprise, were the yellow-rumped warblers. Till now I had never found them at home except in the forests of the White Mountains; but here they were, playing the rôle which in Massachusetts we are accustomed to see taken by the summer yellow-birds, and by no others of the family. At first, knowing that this species was said to build in low evergreens, I looked suspiciously at some small spruces which lined the walk to the pier; but after a while I happened to see one of the birds flying into a rock-maple with something in his bill, and following him with my eye, beheld him alight on the edge of his nest. "About four feet from the ground," the book said (the latest book, too); but this lawless pair had chosen a position which could hardly be less than ten times that height,—considerably higher, at all events, than the eaves of the three-story house. It was out of reach in the small topmost branches, but I watched its owners at my leisure, as the maple was not more than two rods from my window. At this time the nestlings were nearly ready to fly, and in the course of a day or two I saw one of them sitting in a tree in the midst of a drenching rain. On my offering to lay hold of him he dropped into the grass, and when I picked him up both parents began to fly about me excitedly, with loud outcries. The male, especially, went nearly frantic, entering the bowling alley where I happened to be, and alighting on the floor; then, taking to the bole of a tree, he fluttered helplessly upon it, spreading his wings and tail, seeming to say as plainly as words could have done, "Look, you monster! here's another young bird that can't fly; why don't you come and catch him?" The acting was admirable,—all save the spreading of the tail; that was a false note, for the youngster in my hand had no tail feathers at all. I put the fellow upon a tree, whence he quickly flew to the ground (he could fly down but not up), and soon both parents were again supplying him with food. The poor thing had not eaten a morsel for possibly ten minutes, a very long fast for a bird of his age. I hoped he would fall into the hands of no worse enemy than myself, but the chances seemed against him. The first few days after quitting the nest must be full of perils for such helpless innocents.
