We have no well-known pastoral bird in the Eastern States that answers to the skylark. The American pipit or titlark and the shore lark, both birds of the far north, and seen in the States only in fall and winter, are said to sing on the wing in a similar strain. Common enough in our woods are two birds that have many of the habits and manners of the lark--the water-thrush and the golden-crowned thrush, or oven-bird. They are both walkers, and the latter frequently sings on the wing up aloft after the manner of the lark. Starting from its low perch, it rises in a spiral flight far above the tallest trees, and breaks out in a clear, ringing, ecstatic song, sweeter and more richly modulated than the skylark's, but brief, ceasing almost before you have noticed it; whereas the skylark goes singing away after you have forgotten him and returned to him half a dozen times. But on the Great Plains, of the West there; is a bird whose song resembles the skylark's quite closely and is said to be not at all inferior. This is Sprague's pipit, sometimes called the Missouri skylark, an excelsior songster, which from far up in the transparent blue rains down its notes for many minutes together. It is, no doubt, destined to figure in the future poetical literature of the West. Throughout the northern and eastern parts of the Union the lark would find a dangerous rival in the bobolink, a bird that has no European prototype, and no near relatives anywhere, standing quite alone, unique, and, in the qualities of hilarity and musical tintinnabulation, with a song unequaled. He has already a secure place in general literature, having been laureated by no less a poet than Bryant, and invested with a lasting human charm in the sunny page of Irving, and is the only one of our songsters, I believe, that the mockingbird cannot parody or imitate. He affords the most marked example of exuberant pride, and a glad, rollicking, holiday spirit, that can be seen among our birds. Every note expresses complacency and glee. He is a beau of the first pattern, and, unlike any other bird of my acquaintance, pushes his gallantry to the point of wheeling gayly into the train of every female that comes along, even after the season of courtship is over and the matches are all settled; and when she leads him on too wild a chase, he turns, lightly about and breaks out with a song is precisely analogous to a burst of gay and self-satisfied laughter, as much as to say, _"Ha! ha! ha! I must have my fun, Miss Silverthimble, thimble, thimble, if I break every heart in the meadow, see, see, see!"_
