Tiny, sparrow-sized parrot of lowlands and foothills in western Ecuador, western Peru, and far southwestern Colombia. Most common in dry habitats such as desert and deciduous forest, but has spread into humid areas in response to deforestation. Green with blue patch behind eye; male also has blue in wings and on rump, but these features can be hidden by folded wings. Typically found in small flocks that give high-pitched, metallic chirps and chatters.
