So far as the chickadee is concerned, I see nothing whatever to wish different; but am glad to believe that, for my day and long after, he will remain the same unassuming, careless-hearted creature that he now is. If I may be allowed the paradox, it would be too bad for him to change, even for the better. But the bluebird, who like the titmouse is hardly to be accounted a musician, does seem to be somewhat blameworthy. Once in a while, it is true, he takes a perch and sings; but for the most part he is contented with a few simple notes, having no semblance of a tune. Possibly he holds that his pure contralto voice (I do not remember ever to have heard from him any note of a soprano, or even of a mezzo-soprano quality) ought by itself to be a sufficient distinction; but I think it likelier that his slight attempt at music is only one manifestation of the habitual reserve which, more than anything else perhaps, may be said to characterize him. How differently he and the robin impress us in this particular! Both take up their abode in our door-yards and orchards; the bluebird goes so far, indeed, as to accept our hospitality outright, building his nest in boxes put up for his accommodation, and making the roofs of our houses his favorite perching stations. But, while the robin is noisily and jauntily familiar, the bluebird maintains a dignified aloofness; coming and going about the premises, but keeping his thoughts to himself, and never becoming one of us save by the mere accident of local proximity. The robin, again, loves to travel in large flocks, when household duties are over for the season; but although the same has been reported of the bluebird, I have never myself seen such a thing, and am satisfied that, as a rule, this gentle spirit finds a family party of six or seven company enough. His reticence, as we cheerfully admit, is nothing to quarrel with; it is all well-bred, and not in the least unkindly; in fact, we like it, on the whole, rather better than the robin's pertness and garrulity; but, none the less, its natural consequence is that the bird has small concern for musical display. When he sings, it is not to gain applause, but to express his affection; and while, in one aspect of the case, there is nothing out of the way in this,—since his affection need not be the less deep and true because it is told in few words and with unadorned phrase,—yet, as I said to begin with, it is hard not to feel that the world is being defrauded, when for any reason, however amiable, the possessor of such a matchless voice has no ambition to make the most of it.
It is always a double pleasure to find a plodding, humdrum-seeming man with a poet's heart in his breast; and a little of the same delighted surprise is felt by every one, I imagine, when he learns for the first time that our little brown creeper is a singer. What life could possibly be more prosaic than his? Day after day, year in and out, he creeps up one tree-trunk after another, pausing only to peer right and left into the crevices of the bark, in search of microscopic tidbits. A most irksome sameness, surely! How the poor fellow must envy the swallows, who live on the wing, and, as it were, have their home in heaven! So it is easy for us to think; but I doubt whether the creeper himself is troubled with such suggestions. He seems, to say the least, as well contented as the most of us; and, what is more, I am inclined to doubt whether any except "free moral agents," like ourselves, are ever wicked enough to find fault with the orderings of Divine Providence. I fancy, too, that we may have exaggerated the monotony of the creeper's lot. It can scarcely be that even his days are without their occasional pleasurable excitements. After a good many trees which yield little or nothing for his pains, he must now and then light upon one which is like Canaan after the wilderness,—"a land flowing with milk and honey." Indeed, the longer I think of it the more confident I feel that every aged creeper must have had sundry experiences of this sort, which he is never weary of recounting for the edification of his nephews and nieces, who, of course, are far too young to have anything like the wide knowledge of the world which their venerable three-years-old uncle possesses. Certhia works all day for his daily bread; and yet even of him it is true that "the life is more than meat." He has his inward joys, his affectionate delights, which no outward infelicity can touch. A bird who thinks nothing of staying by his nest and his mate at the sacrifice of his life is not to be written down a dullard or a drudge, merely because his dress is plain and his occupation unromantic. He has a right to sing, for he has something within him to inspire the strain.
There are descriptions of the creeper's music which liken it to a wren's. I am sorry that I have myself heard it only on one occasion: then, however, so far was it from being wren-like that it might rather have been the work of one of the less proficient warblers,—a somewhat long opening note followed by a hurried series of shorter ones, the whole given in a sharp, thin voice, and having nothing to recommend it to notice, considered simply as music. All the while the bird kept on industriously with his journey up the tree; and it is not in the least unlikely that he may have another and better song, which he reserves for times of more leisure.[19]
Our American wood-warblers are all to be classed among the minor songsters; standing in this respect in strong contrast with the true Old World warblers, of whose musical capacity enough, perhaps, is said when it is mentioned that the nightingale is one of them. But, comparisons apart, our birds are by no means to be despised, and not a few of their songs have a good degree of merit. That of the well-known summer yellow-bird may be taken as fairly representative of the entire group, being neither one of the best nor one of the poorest. He, I have noticed, is given to singing late in the day. Three of the New England species have at the same time remarkably rough voices and black throats,—I mean the black-throated blue, the black-throated green, and the blue golden-wing,—and seeing that the first two are of the genus Dendrœca, while the last is a Helminthophaga, I have allowed myself to query (half in earnest) whether they may not, possibly, be more nearly related than the systematists have yet discovered. Several of the warbler songs are extremely odd. The blue yellow-back's, for example, is a brief, hoarse, upward run,—a kind of scale exercise; and if the practice of such things be really as beneficial as music teachers affirm, it would seem that this little beauty must in time become a vocalist of the first order. Nearly the same might be said of the prairie warbler; but his étude is a little longer and less hurried, besides being in a higher key. I do not call to mind any bird who sings a downward scale. Having before spoken of the tendency of warblers to learn two or even three set tunes, I was the more interested when, last summer, I added another to my list of the species which aspire to this kind of liberal education. It was on the side of Mount Clinton that I heard two Blackburnians, both in full sight and within a few rods of each other, who were singing two entirely distinct songs. One of these—it is the common one, I think—ended quaintly with three or four short notes, like zip, zip, zip; while the other was not unlike a fraction of the winter wren's melody. Those who are familiar with the latter bird will perhaps recognize the phrase referred to if I call it the willie, willie, winkie,—with a triple accent on the first syllable of the last word. Most of the songs of this family are rather slight, but the extremest case known to me is that of the black-poll (Dendrœca striata), whose zee, zee, zee is almost ridiculously faint. You may hear it continually in the higher spruce forests of the White Mountains; but you will look a good many times before you discover its author, and not improbably will begin by taking it for the call of the kinglet. The music of the bay-breasted warbler is similar to the black-poll's, but hardly so weak and formless. It seems reasonable to believe not only that these two species are descended from a common ancestry, but that the divergence is of a comparatively recent date: even now the young of the year can be distinguished only with great difficulty, although the birds in full feather are clearly enough marked.
Warblers' songs are often made up of two distinct portions: one given deliberately, the other hurriedly and with a concluding flourish. Indeed, the same may be said of bird-songs generally,—those of the song sparrow, the bay-winged bunting, and the wood thrush being familiar examples. Yet there are many singers who attempt no climax of this sort, but make their music to consist of two, or three, or more parts, all alike. The Maryland yellow-throat, for instance, cries out over and over, "What a pity, what a pity, what a pity!" So, at least, he seems to say; though, I confess, it is more than likely I mistake the words, since the fellow never appears to be feeling badly, but, on the contrary, delivers his message with an air of cordial satisfaction. The song of the pine-creeping warbler is after still another fashion,—one simple short trill. It is musical and sweet; the more so for coming almost always out of a pine-tree.
The vireos, or greenlets, are akin to the warblers in appearance and habits, and like them are peculiar to the western continent. We have no birds that are more unsparing of their music (prodigality is one of the American virtues, we are told): they sing from morning till night, and—some of them, at least—continue thus till the very end of the season. It is worth mentioning, however, that the red-eye makes a short day; becoming silent just at the time when the generality of birds grow most noisy. Probably the same is true of the rest of the family, but on that point I am not prepared to speak with positiveness. Of the five New England species (I omit the brotherly-love greenlet, never having been fortunate enough to know him) the white-eye is decidedly the most ambitious, the warbling and the solitary are the most pleasing, while the red-eye and the yellow-throat are very much alike, and both of them rather too monotonous and persistent. It is hard, sometimes, not to get out of patience with the red-eye's ceaseless and noisy iteration of his trite theme; especially if you are doing your utmost to catch the notes of some rarer and more refined songster. In my note-book I find an entry describing my vain attempts to enjoy the music of a rose-breasted grosbeak,—who at that time had never been a common bird with me,—while "a pesky Wagnerian red-eye kept up an incessant racket."
The warbling vireo is admirably named; there is no one of our birds that can more properly be said to warble. He keeps further from the ground than the others, and shows a strong preference for the elms of village streets, out of which his delicious music drops upon the ears of all passers underneath. How many of them hear it and thank the singer is unhappily another question.
The solitary vireo may once in a while be heard in a roadside tree, chanting as familiarly as any red-eye; but he is much less abundant than the latter, and, as a rule, more retiring. His ordinary song is like the red-eye's and the yellow-throat's, except that it is pitched somewhat higher and has a peculiar inflection or cadence, which on sufficient acquaintance becomes quite unmistakable. This, however, is only the smallest part of his musical gift. One morning in May, while strolling through a piece of thick woods, I came upon a bird of this species, who, all alone like myself, was hopping from one low branch to another, and every now and then breaking out into a kind of soliloquizing song,—a musical chatter, shifting suddenly to an intricate, low-voiced warble. Later in the same day I found another in a chestnut grove. This last was in a state of quite unwonted fervor, and sang almost continuously; now in the usual disconnected vireo manner, and now with a chatter and warble like what I had heard in the morning, but louder and longer. His best efforts ended abruptly with the ordinary vireo call, and the instantaneous change of voice gave to the whole a very strange effect. The chatter and warble appeared to be related to each other precisely as are those of the ruby-crowned kinglet; while the warble had a certain tender, affectionate, some would say plaintive quality, which at once put me in mind of the goldfinch.
I have seldom been more charmed with the song of any bird than I was on the 7th of last October with that of this same Vireo solitarius. The morning was bright and warm, but the birds had nearly all taken their departure, and the few that remained were silent. Suddenly the stillness was broken by a vireo note, and I said to myself with surprise, A red-eye? Listening again, however, I detected the solitary's inflection; and after a few moments the bird, in the most obliging manner, came directly towards me, and began to warble in the fashion already described. He sang and sang,—as if his song could have no ending,—and meanwhile was flitting from tree to tree, intent upon his breakfast. As far as I could discover, he was without company; and his music, too, seemed to be nothing more than an unpremeditated, half-unconscious talking to himself. Wonderfully sweet it was, and full of the happiest content. "I listened till I had my fill," and returned the favor, as best I could, by hoping that the little wayfarer's lightsome mood would not fail him, all the way to Guatemala and back again.
Exactly a month before this, and not far from the same spot, I had stood for some minutes to enjoy the "recital" of the solitary's saucy cousin, the white-eye. Even at that time, although the woods were swarming with birds,—many of them travelers from the North,—this white-eye was nearly the only one still in song. He, however, was fairly brimming over with music; changing his tune again and again, and introducing (for the first time in Weymouth, as concert programmes say) a notably fine shake. Like the solitary, he was all the while busily feeding (birds in general, and vireos in particular, hold with Mrs. Browning that we may "prove our work the better for the sweetness of our song"), and one while was exploring a poison-dogwood bush, plainly without the slightest fear of any ill-result. It occurred to me that possibly it is our fault, and not that of Rhus venenata, when we suffer from the touch of that graceful shrub.
