A very small, gregarious parrot that prefers open habitats where it feeds on fruits, flowers, and seeds. The only parrotlet to occur in the Caribbean. Elsewhere told from other parrotlets by uniform lime-green color (plus blue wing patch in males) and pale bill. Most often seen flying in small tight flocks that frequently tilt and make abrupt turns. Usually first detected by its calls, which are a combination of shrill chatterings, squeaks, twitters.
