Small flycatcher of rainforest canopy. Olive with bright white or buffy wing bars and a gray head. Black eye line with white extending from the base of the bill to above and behind the eye. Bold wing bars help distinguish it from similar flycatchers; also, note darker olive plumage and clean facial pattern. Forages singly or in pairs in the canopy of mature rainforest, and, like many rainforest tyrannulets, can be quite inconspicuous. Listen for its voice, a slightly accelerating series of 4-5 high whistles: “pwee, pwee, pwee-pee.”
