Grisin à épaules rousses Euchrepomis humeralis

Small canopy antwren. Gray head, with yellowish underparts, and wingbars; males have a fine black eyeline and cap. Less apparent field marks are its small reddish shoulder patch and reddish back patch. Moves more sluggishly than greenlets or tanagers, which it often joins in mixed-species flocks. Its song is an accelerating series of high, thin notes.
