Forest Elaenia Myiopagis gaimardii

This nondescript flycatcher is most often detected by its call, a piercing two-parted “pee-sweet!” Visually it’s not overwhelming: yellowish underparts, olive upperparts, pale yellowish wingbars, and a gray head with a vague white eyebrow and black eyeline. Fairly small and similar to other species of elaenia and flycatchers; voice is most useful feature for identification. Usually seen singly in the canopy of lowland forest, often following mixed-species flocks. Widespread from Panama to Brazil.
