Double-toothed Kite
Harpagus bidentatus
The double-toothed kite (Harpagus bidentatus) is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found from central Mexico through Central America into much of northern and eastern South America.
Males and females have similar plumage though the females' colors are richer. Adults of both subspecies have a dark gray head with a white throat that has a dark stripe down its center. Their upperparts are a somewhat lighter gray and their tail blackish with three grayish bands and a gray tip. Their eyes are red, their cere greenish yellow, and their legs and feet yellow. The nominate subspecies has a rufous breast, a rufous belly with gray and whitish barring that sometimes extends into the lower breast, and white undertail coverts. Adults of subspecies H. b. fasciatus have similar underparts to the nominate but the rufous is paler and less extensive and the barring heavier and more extensive. Immatures of both subspecies have deep brown upperparts and whitish to buff underparts with bold vertical brown streaks.
