Lemon-spectacled Tanager Chlorothraupis olivacea

Chunky tanager, unlikely to be mistaken within limited range from eastern Panama to extreme northwest Ecuador. Mostly dull olive with brighter yellow throat and bold yellow spectacles. Note its stout bill. Sexes similar. Prefers the interior of humid lowland forest, up to around 400 m. Typically found in small groups or pairs in the understory to middle levels, often with mixed-species flocks. Often detected by its loud squeaky chatters.
