コタイランチョウ Phyllomyias fasciatus

Tiny flycatcher with a shortish dark bill, dark legs, and a long slender tail. It has an olive-gray back, a pale face, a gray cap, and is pale yellow below. Note the white eyerings and two pale wingbars. Subspecies vary in plumage intensity. Found in the canopy of humid forests and woodlands where it often joins mixed-species flocks. The song is a quiet series of three notes “pew-pew-puuit.”
