see text Manacus is a genus of passerine birds in the manakin family which are found in the forests of tropical mainland Central and South America, and on Trinidad and Tobago.

The males have brightly coloured plumage and long puffed throat feathers, whereas the females are the typical manakin dull olive hue.

Nest-building, incubation for 18–21 days, and care of the young are undertaken by the female alone, since manakins do not form stable pairs.

Like some other manakin species, this genus has spectacular courtship rituals, in which the males give communal displays in a specially prepared lek.

The males jump with their throat feathers erected to form a beard, and give whistles together with the characteristic loud snaps (like a breaking twig) and various buzzing, rustling and whiffling noises made with the wings.
