Scarce and inconspicuous rainforest bird found along the lower slopes of the eastern Andes and adjacent lowlands. Both male and female have uniform olive-green plumage and may show a very faint, pale eyering. Very similar to female Jet Manakin, but brighter, lacking dusky tones. Separated from females of other manakins by its longer tail and grayish legs. Usually remains quiet, but occasionally gives a thin, rising whistle or a short, metallic trill.
