Of all our unimitative and natural songsters the Bobolink is by far the most popular and attractive. Always original and peculiarly natural, its song is exquisitely musical. In the variety of its notes, in the rapidity with which they are uttered, and in the touching pathos, beauty, and melody of their tone and expression, its notes are not equalled by those of any other North American bird. We know of none, among our native feathered songsters, whose song resembles, or can be compared with it. In the earliest approaches of spring, in Louisiana, when small flocks of male Bobolinks make their first appearance, they are said, by Mr. Audubon, to sing in concert; and their song thus given is at once exceedingly novel, interesting, and striking. Uttered with a volubility that even borders upon the burlesque and the ludicrous, the whole effect is greatly heightened by the singular and striking manner in which first one singer and then another, one following the other until all have joined their voices, take up the note and strike in, after the leader has set the example and given the signal. In this manner sometimes a party of thirty or forty Bobolinks will begin, one after the other, until the whole unite in producing an extraordinary medley, to which no pen can do justice, but which is described as very pleasant to listen to. All at once the music ceases with a suddenness not less striking and extraordinary. These concerts are repeated from time to time, usually as often as the flock alight. This performance may also be witnessed early in April, in the vicinity of Washington, the Smithsonian grounds being a favorite place of resort.
