An unobtrusive, sparrow-sized bird of rainforest understory. Male is glossy black with a bright blue rump, a shining white forehead, a large yellow central breast spot, and a yellow belly. Females are bright green, yellower on the belly. A common resident of tall rainforest, where it consumes fruits of understory shrubs. Males take exposed song perches, usually within 5 meters of the ground, from which they give a repeated purring note that could easily be mistaken for a frog. Otherwise most likely to be seen at fruiting shrubs. Very similar Orange-bellied Manakin does not overlap in range. Females best distinguished from other manakins by bright green plumage and strong yellow tones on belly.
