olivenbrysttyrann Myiophobus cryptoxanthus

Drab and unremarkable flycatcher found in the eastern foothills of the Andes in Ecuador and northern Peru. Note grayish-olive upperparts, dingy white underparts, yellow tinge to the belly, and pale wingbars. Yellow crown stripe is usually concealed. Habitat is a good ID clue: it perches low in grassy clearings with scattered bushes and small trees, and never ventures inside forest. Call is an inflected whistle repeated every few seconds, and song is a short, rising trill.
