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.

conspicuous dark cheek patches underparts mostly tawny buff tail black, with two narrow white bars. Males and females are alike the young have the underparts white with brown streaks, and the tail with six to eight white bars. The young of these three species of Buteo are similar, but may be distinguished from each other by the following marks the gray tail with narrow black bars of the Red-tail the red shoulder and barred quills of the Red-shoulder and besides the smaller size, the dark cheek patches of the Broad-wing.











Another distinguishing mark is the Red-tail and Red-shoulder have the first four quills of their wings notched on the inner van, whereas' the Broad-wing has only three quills notched. They all differ from the Accipiters by their tail markings, by being much more strongly built, and by having no round white spots on the feathers of the back between the shoulders.
