Orange-bellied Manakin

The orange-bellied manakin is about 9 cm (3.5 in) long; one male weighed 8.5 g (0.30 oz). The species is sexually dimorphic. Adult males have a white forecrown, a bright azure-blue lower rump and uppertail coverts, and a yellow-orange belly. The rest of their plumage is black. Adult females have a bluish forehead, a grayish face and throat, and a yellow belly and undertail coverts. The rest of their plumage is green. Both sexes have a dark brown iris, a black bill, and grayish to almost black legs and feet. Voice: The male orange-bellied manakin's "advertising" call is "a short, nasal, slightly rising aank" that has been likened to a frog's voice. Other vocalizations include "a rapid warbling or fluttery series...whee-pee-pee-pi-pi-pe-pee", a "quavering wu WE WE wa we we wit", and a "short, slow trill, pr'r'r'r". The last is usually alternated with the aank call.
