The bobolink (Dolichonyx oryzivorus) is a medium-sized songbird that can be measured between 5½ and 7½ inches in length. It is the only North American songbird that is white on the back and black underneath. The bobolink has a short bill with short pointed tail, with feathers similar to those of a woodpecker.
