above underparts white, covered thickly with rustcolored bars bend of wing rich chestnut tail black, with four or five narrow Avhite bars. Males and females are alike, and the young are similar, but with the bars on their quills and tail tawny instead of Avhite, and the underparts white with brown streaks, like No. 11a on plate, with no reddish anywhere except on the shoulder.
