Lark Bunting, a shy bird of the Finch Family, about the size of the English sparrow and easily recognized by its black color, white wing patches and white marks on the tail. The female is brown, streaked with blackish above, and with black and white below. The wing patch is smaller than in the male. The nest is made of grass and rootlets and is sunk in the ground, usually under a clump of weeds. Four to five blue eggs are laid. The lark bunting occurs in large flocks on the plains and prairies in summer, but they winter in Mexico. During the nesting season they have a pleasant and rich song.
