The extent of the chestnut of the crown varies somewhat; more extended probably in the males. The region on the side of the head, adjoining the nostrils, is whitish; the small feathers under the eye are spotted with the same. The posterior outline of the ash of the breast is much less sharply defined than the anterior.
Specimens vary in the brightness of the olive above, which is never as pure as that of the wings and tail. The olive of the tail, too, is darker than that of the wings.
Pipilo chlorurus.
