A small, plump, and short-tailed manakin with a restricted range in Panama and western Colombia. Males are striking with a bright yellow throat and collar, a black cap, and a black back with greenish rump and belly. Females are entirely olive-green with red legs and dark bill and eye. Hybridizes with White-collared and White-bearded Manakins; hybrid males typically have yellow upper backs. Apparently no range overlap with similar Orange-collared Manakin. Occurs in dense understory of forest, second growth, and edges. Males gather in groups to display for females; otherwise most likely to be found at a fruiting tree or sitting quietly in the lower levels of forest.
