Red-headed Manakin
Ceratopipra rubrocapilla
The red-headed manakin is 10 to 10.5 cm (3.9 to 4.1 in) long and weighs about 11 to 17 g (0.39 to 0.60 oz). The species is sexually dimorphic and females are heavier than males. Adult males have an almost entirely red head and neck. Their thighs are also red. Their throat and the rest of their plumage are black. Adult females are mostly dull olive-green; their underparts are lighter than their back, especially on the belly. Both sexes have dull pinkish legs and feet. Males have a hazel-brown iris and a pale brownish bill; the female's iris and bill are darker. Voice: The male red-headed manakin's principal call is a somewhat variable "drree-dit, dree-dee-dew". It also makes a "sharp zit, zit" call and during the display flight "a series of kew notes".
