American sparrow

American sparrows are a group of mainly New World passerine birds, forming part of the family Emberizidae. American sparrows are seed-eating birds with conical bills, brown or gray in color, and many species have distinctive head patterns.

Although they share the name sparrow, American sparrows are more closely related to Old World buntings (which are also in the family Emberizidae) than they are to the Old World sparrows (family Passeridae). American sparrows are also similar in both appearance and habit to finches, with which they sometimes used to be classified.
