The Vesper-bird attracts more general attention to his notes than the Sparrow, because he sings a longer, though a more monotonous song, and warbles with more fervency. His notes bear considerable resemblance to those of the Canary-bird, but they are more subdued and plaintive, and have a peculiar reedy sound, which is never perceived in the notes of the Canary. This bird is periodical in his habits of song, confining his lays to particular hours of the day and conditions of the weather. The Song-Sparrow, on the contrary, sings about equally from morning to night, and but little more at one hour than another; and the different performers of this species do not seem to join in concert. This habit renders the latter more companionable, at the same time it causes his notes to be less regarded than those of the Vesper-bird, who pours them forth more sparingly, and at regular periods. The Vesper-bird begins with all his kindred in a general concert at early dawn, after which they are comparatively silent until sunset, when they repeat their concert, with still greater zeal than they chanted in the morning. It is from this circumstance that it has obtained the name it bears--from its evening hymn, or vespers. I have heard this name applied to it only in one locality; but it is so precisely applicable to its habits, that I have thought it worthy of being retained as its distinguishing cognomen. There are particular states of the weather that frequently call out the birds of this species into a general concert at other periods of the day--as when rain is suddenly followed by sunshine, or when a clear sky is suddenly darkened by clouds, presenting to them a sort of occasional morn and occasional even. It may be remarked, that you seldom hear one of these birds singing alone; but when one begins, all others in the vicinity immediately join him. The usual resorts of the Vesper-bird are the pastures and the hay-fields; hence the name of Grass-Finch, by which he is usually distinguished. His voice is heard frequently by the rustic roadsides, where he picks up a considerable portion of his subsistence. This is the little bird that so generally serenades us during our evening walks, at a little distance from the town, and not so far into the woods as the haunts of the Thrushes. When we go out into the country, on pleasant days in June or July, at nightfall, we hear multitudes of them singing sweetly from a hundred different points in the fields and farms.
