Robins sang sparingly from the beginning, and became perceptibly more musical on the 8th, with signs of mating and jealousy; but the real robin carnival did not open till the morning of the 14th. Then the change was wonderful. Some of the birds were flying this way and that, high in air, two or three together; others chased each other about nearer the ground; some were screaming, some hissing, and more singing. So sudden was the outbreak and so great the commotion that I was persuaded there must have been an arrival of females in the night.
I have heard it objected against these thrushes, whose extreme commonness renders them less highly esteemed than they would otherwise be, that they find their voices too early in the morning. But I am not myself prepared to second the criticism. They are not often at their matins, I think, until the eastern sky begins to flush, and it is not quite certain to my mind that they are wrong in assuming that daylight makes daytime. I have questioned before now whether our own custom of sitting up for five or six hours after sunset, and then lying abed two or three hours after sunrise, may not have come down to us from times when there were still people in the world who loved darkness rather than light, because their deeds were evil; and whether, after all, in this as in some other respects, we might not wisely take pattern of the fowls of the air.
Individually, the phœbes were almost as noisy as the robins, but of course their numbers were far less. They are models of perseverance. Were their voice equal to the nightingale's they could hardly be more assiduous and enthusiastic in its use. As a general thing they are content to repeat the simple Phœbe, Phœbe (there are moods in the experience of all of us, I hope, when the repetition of a name is by itself music sufficient), but it is not uncommon for this to be heightened to Phœbe, O Phœbe; and now and then you will hear some fellow calling excitedly, Phœbe, Phœbe-be-be-be-be,—a comical sort of stuttering, in which the difficulty is not in getting hold of the first syllable, but in letting go the last one. On the 15th I witnessed a certain other performance of theirs,—one that I had seen two or three times the season previous, and for which I had been on the lookout from the first day of the month. I heard a series of chips, which might have been the cries of a chicken, but which, it appeared, did proceed from a phœbe, who, as I looked up, was just in the act of quitting his perch on the ridge-pole of a barn. He rose for perhaps thirty feet, not spirally, but in a zigzag course,—like a horse climbing a hill with a heavy load,—all the time calling, chip, chip, chip. Then he went round and round in a small circle, with a kind of hovering action of the wings, vociferating hurriedly, Phœbe, Phœbe, Phœbe; after which he shot down into the top of a tree, and with a lively flirt of his tail took up again the same eloquent theme. During the next few weeks I several times found birds of this species similarly engaged. And it is worthy of remark that, of the four flycatchers which regularly pass the summer with us, three may be said to be, in the habit of singing in the air, while the fourth (the wood pewee) does the same thing, only with less frequency. It is curious, also, on the other hand, that not one of our eight common New England thrushes, as far as I have ever seen or heard, shows the least tendency toward any such state of lyrical exaltation. Yet the thrushes are song birds par excellence, while the phœbe, the least flycatcher, and the kingbird are not supposed to be able to sing at all. The latter have the soul of music in them, at any rate; and why should it not be true of birds, as it is of human poets and would-be poets, that sensibility and faculty are not always found together? Perhaps those who have nothing but the sensibility have, after all, the better half of the blessing.
The golden-winged woodpeckers shouted comparatively little before the middle of the month, and I heard nothing of their tender wick-a-wick until the 22d. After that they were noisy enough. With all their power of lungs, however, they not only are not singers; they do not aspire to be. They belong to the tribe of Jubal. Hearing somebody drumming on tin, I peeped over the wall, and saw one of these pigeon woodpeckers hammering an old tin pan lying in the middle of the pasture. Rather small sport, I thought, for so large a bird. But that was a matter of opinion, merely, and evidently the performer himself had no such scruples. He may even have considered that his ability to play on this instrument of the tinsmith's went far to put him on an equality with some who boast themselves the only tool-using animals. True, the pan was battered and rusty; but it was resonant, for all that, and day after day he pleased himself with beating reveille upon it. One morning I found him sitting in a tree, screaming lustily in response to another bird in an adjacent field. After a while, waxing ardent, he dropped to the ground, and, stationing himself before his drum, proceeded to answer each cry of his rival with a vigorous rubadub, varying the programme with an occasional halloo. How long this would have lasted there is no telling, but he caught sight of me, skulking behind a tree-trunk, and flew back to his lofty perch, where he was still shouting when I came away. It was observable that, even in his greatest excitement, he paused once in a while to dress his feathers. At first I was inclined to take this as betraying a want of earnestness; but further reflection led me to a different conclusion. For I imagine that the human lover, no matter how consuming his passion, is seldom carried so far beyond himself as not to be able to spare now and then a thought to the parting of his hair and the tie of his cravat.
Seeing the great delight which this woodpecker took in his precious tin pan, it seemed to me not at all improbable that he had selected his summer residence with a view to being near it, just as I had chosen mine for its convenience of access to the woods on the one hand, and to the city on the other. I shall watch with interest to see whether he returns to the same pasture another year.
A few field sparrows and chippers showed themselves punctually on the 15th; but they were only scouts, and the great body of their followers were more than a week behind them. I saw no bay-winged buntings until the 22d, although it is likely enough they had been here for some days before that. By a lucky chance, my very first bird was a peculiarly accomplished musician: he altered his tune at nearly every repetition of it, sang it sometimes loudly and then softly, and once in a while added cadenza-like phrases. It lost nothing by being heard on a bright, frosty morning, when the edges of the pools were filmed with ice.
Only three species of warblers appeared during the month: the pine-creeping warblers, already spoken of, who were trilling on the 14th; the yellow-rumped, who came on the 23d; and the yellow red-polls, who followed the next morning. The black-throated greens were mysteriously tardy, and the black-and-white creepers waited for May-day.
A single brown thrush was leading the chorus on the 29th. "A great singer," my note-book says: "not so altogether faultless as some, but with a large voice and style, adapted to a great part;" and then is added, "I thought this morning of Titiens, as I listened to him!"—a bit of impromptu musical criticism, which, under cover of the saving quotation marks may stand for what it is worth.
Not long after leaving him I ran upon two hermit thrushes (one had been seen on the 25th), flitting about the woods like ghosts. I whistled softly to the first, and he condescended to answer with a low chuck, after which I could get nothing more out of him. This demure taciturnity is very curious and characteristic, and to me very engaging. The fellow will neither skulk nor run, but hops upon some low branch, and looks at you,—behaving not a little as if you were the specimen and he the student! And in such a case, as far as I can see, the bird equally with the man has a right to his own point of view.
The hermits were not yet in tune; and without forgetting the fox-colored sparrows and the linnets, the song sparrows and the bay-wings, the winter wrens and the brown thrush, I am almost ready to declare that the best music of the month came from the smallest of all the month's birds, the ruby-crowned kinglets. Their spring season is always short with us, and unhappily it was this year shorter even than usual, my dates being April 23d and May 5th. But we must be thankful for a little, when the little is of such a quality. Once I descried two of them in the topmost branches of a clump of tall maples. For a long time they fed in silence; then they began to chase each other about through the trees, in graceful evolutions (I can imagine nothing more graceful), and soon one, and then the other, broke out into song. "'Infinite riches in a little room,'" my note-book says, again; and truly the song is marvelous,—a prolonged and varied warble, introduced and often broken into, with delightful effect, by a wrennish chatter. For fluency, smoothness, and ease, and especially for purity and sweetness of tone, I have never heard any bird-song that seemed to me more nearly perfect. If the dainty creature would bear confinement,—on which point I know nothing,—he would make an ideal parlor songster; for his voice, while round and full,—in contrast with the goldfinch's, for example,—is yet, even at its loudest, of a wonderful softness and delicacy. Nevertheless, I trust that nobody will ever cage him. Better far go out-of-doors, and drink in the exquisite sounds as they drop from the thick of some tall pine, while you catch now and then a glimpse of the tiny author, flitting busily from branch to branch, warbling at his work; or, as you may oftener do, look and listen to your heart's content, while he explores some low cedar or a cluster of roadside birches, too innocent and happy to heed your presence. So you will carry home not the song only, but "the river and sky."
