THE BIRDS OF THE GARDEN AND ORCHARD.
The singing-birds whose notes are familiar to us, in towns and villages and the suburbs of the city, are found in the breeding-season only in these places, and are strangers to the deep woods and solitary pastures. Most of our singing-birds follow in the wake of the pioneer of the wilderness, and increase in numbers with the clearing and settlement of the country,—not, probably, from any dependence on the protection of mankind, but on account of the increased abundance of the insect food upon which they subsist, consequent upon the tilling of the ground. It is well known that the labors of the husbandman cause an excessive multiplication of all those species of insects whose larvae are cherished in the soil, and of all that infest the orchard and garden. The farm is capable of supporting insects just in proportion to its capacity for producing corn and fruit. Insects will multiply with their means of subsistence in and upon the earth; and birds, if not destroyed by artificial methods, will increase in proportion to the multiplication of those insects which constitute their principal food.
These considerations will sufficiently account for the fact, which often excites a little astonishment, that more singing-birds are found in the suburbs of the city, and among the parks and gardens of the city, than in the deep forest, where, even in the singing-season, the silence is sometimes melancholy. It is still to be remarked, that the species which are thus familiar in their habits do not include all the singing-birds, but they include all that are well known to the majority of our people. These are the birds of the garden and orchard. There are many other species, wild and solitary in their habits, which are delightful songsters in uncultivated regions remote from the town. But even these are rare in the depths of the forest. They live on the edge of the wood and in the half-wooded pasture.
The birds of the garden and orchard have been frequently described, and their habits are very generally known; but in the usual descriptions little has been said of their powers and peculiarities of song. In the present sketches, I have given particular attention to the vocal powers of the different birds, and have endeavored to designate the parts which each one performs in the grand hymn of Nature. I shall first introduce the Song-Sparrow, (Fringilla melodia,) a little bird that is universally known and admired. The Song-Sparrow is the earliest visitant and the latest resident of the vocal tenants of the field. He is plain in his vesture, undistinguished from the female by any superiority of plumage, and comes forth in the spring and takes his departure in the autumn in the same suit of russet and gray by which he is always recognized.
In March, before the violet has ventured to peep out from the southern knoll of the pasture or the sunny brow of the hill, while the northern skies are liable to pour down at any hour a storm of sleet and snow, the Song-Sparrow, beguiled by southern winds, has already made his appearance, and, on still mornings, may be heard warbling his few merry notes, as if to make the earliest announcement of his arrival. He is, therefore, the true harbinger of spring, and, though not the sweetest songster of the woods, has the merit of bearing to man the earliest tidings of the opening year, and of declaring the first vernal promises of Nature. As the notes of those birds that sing only in the night come with a double charm to our ears, because they are harmonized by silence and hallowed by the hour that is sacred to repose—in like manner does the Song-Sparrow delight us in tenfold measure, because he sings the sweet prelude to the universal hymn of Nature.
His haunts are the pastures which have been half reduced to tillage, and are still partially filled with wild shrubbery; for he is not so familiar in his habits as the Hair-bird, that comes close up to our door-step, to find the crumbs that are swept from our tables. Though his voice is constantly heard in the garden and orchard, he selects a more retired spot for his nest, preferring not to trust his progeny to the doubtful mercy of the lords of creation. In some secure retreat, under a tussock of herbage or a tuft of shrubbery, the female sits upon her nest of soft dry grass, containing four or five eggs, of a greenish white ground, almost entirely covered with brownish specks. Commencing in April, she rears three broods of young during the season, and her mate prolongs his notes until the last brood has flown from the nest.
The notes of the Song-Sparrow would not entitle him to be ranked among our principal singing-birds, were it not for the remarkable variations of his song, in which respect he is equalled, I think, by no other bird. Of these variations there are seven or eight which may be distinctly recognized, and differing enough to be considered separate tunes. The bird does not warble these in regular succession; he is in the habit of repeating one several times, and then leaves it, and repeats another in a similar manner. Mr. Paine[1] took note, on one occasion, of the number of times a Song-Sparrow sang each of the tunes, and the order of singing them. Of the tunes, as he had numbered them, the bird "sang No. 1, 27 times; No. 2, 36 times; No. 3, 23 times; No. 4, 19 times; No. 5, 21 times; No. 6, 32 times; No. 7, 18 times. Perhaps next he would sing No. 2, then perhaps No. 4, or 5, and so on." Mr. Paine adds, "Some males will sing each tune about fifty times, though seldom; some will only sing them from five to ten times. But as far as I have observed, each male has his seven songs. I have applied the rule to as many as a dozen different birds, and the result has been the same."
An individual will sometimes, for half a day, confine himself almost entirely to a few of these variations; but he will commonly sing each one more or less in the course of the day. I have observed also, that, when one principal singer takes up a particular tune, other birds in the vicinity will unite in the same. The several variations are mostly in triple time, a few in common time, and there is an occasional blending of both in the same tune, which consists usually of four bars or strains, sometimes five, though the song is frequently broken off at the end of the third strain. This habit of varying his notes through so many permutations, and the singularly fine intonations of many of them, entitle the Song-Sparrow to a very high rank as a singing-bird.
There is a manifest difference in the expression of these several tunes. The one which I have marked as No. 3 is particularly plaintive, and is usually in common time. No. 2 is the one which I think is most frequently sung. No. 5 is querulous and entirely unmusical. There is a remarkable precision in the song of this bird, and the finest singers are those which, in the language of musicians, have the least execution. There are some individuals that blend their notes together so promiscuously, and use so many flourishes, that it is difficult to identify their song, or to perceive its expression. Whether these tunes of the Song-Sparrow express to his mate, or to others of his species, different sentiments, and convey different messages, or whether the bird adopts them for his own amusement, I have not been able to determine. Neither have I learned whether a certain hour of the day or a certain state of the weather predisposes him to sing a particular tune. This point may, perhaps, be determined by some future observer; and it may be ascertained that the birds of this species have their matins and their vespers, their songs of rejoicing and of complaining, of courtship when in presence of their mate, and of encouragement and solace when she is sitting upon her nest. As Nature has a benevolent and a definite object in every instinct which she has established among her creatures, it is not probable that this habit of the Song-Sparrow is the mere result of accident. All the variations of his song are given, with the specimens, at the end of this article, and, though individuals differ in their singing, the notes will afford the reader a good general idea of the several tunes.
Soon after the arrival of the Song-Sparrow, when the spring-flowers have begun to be conspicuous in the meadow, we are greeted by the more fervent and lengthened notes of the Vesper-bird, (Fringilla graminea,) poured out with a peculiarly pensive modulation. This species closely resembles the former, but may be distinguished from it, when on the wing, by two white lateral feathers in the tail. The chirp of the Song-Sparrow is also louder, and pitched on a lower key, than that of the present species. By careless observers, these two Finches, on account of the similarity in their general appearance and habits, are considered identical. The Vesper-bird, however, is the least familiar of the two, and, when both are singing at the same time, will be found to occupy a position more remote from the house than the other. In several localities, these two species are distinguished by the names of Bush-Sparrow and Ground-Sparrow, from their supposed different habits of placing their nests, one in a bush and the other on the ground. But they do not in fact differ in this respect, as each species occasionally builds in both ways.
