Tiny, inconspicuous manakin of lowland rainforest canopy. Adult male is unmistakable; females and young males are told by slim shape and crisp two-toned appearance. Generally seen less often than other manakins; feeds on fruit in midstory and canopy, occasionally in understory. Usually detected by its thin, lisping call, which is strikingly similar to that of Ruddy-tailed Flycatcher, but with 3–4 (not 2) syllables and falling in pitch. Male display, rarely seen, is centered on fallen logs.
