An inconspicuous, small, green bird of the tepui highlands. Key marks are entirely olive-green plumage and yellowish eyering. Inhabits humid, mossy forest undergrowth on tepui slopes, most commonly above 800 m but occasionally lower. Generally solitary, quiet, and easily overlooked; most likely to be seen feeding at fruiting shrubs. Calls include a high, wheezing note that may rise and fall in pitch. Distinctive eyering should easily separate this species from other manakins at higher elevations in the tepuis. Below 800 m, told from Olivaceous Schiffornis by smaller size, shorter tail, and strongly olive-green plumage. Told from female Black Manakin by eyering and olive plumage.
