The Versicolored Emerald is a small species of Amazilia hummingbird. It is discontinuously distributed in open habitats of eastern South America, from Colombia east to the Guianas and south to northeastern Argentina and southern Brazil. This is a medium-sized hummingbird with green upperparts and white underparts; the mostly pink mandible helps to distinguish it from the very similar White-chested Emerald (Amazilia chionopectus). There are six subspecies of Versicolored Emerald, which vary in features such as the color of the crown (glittering green or turquoise) and throat (white, or variably green or turquoise). One poorly-known subspecies, rondoniae of southwestern Brazil (and northern Bolivia?), sometimes is recognized as a separate species, but geographic variation within Versicolored Emerald merits further study. Across its broad range, the Versicolored Emerald behaves as a typical Amazilia: it occurs at the edges of forest, in open shrubby areas, and in savannas with scattered trees or shrubs. Versicolored Emeralds feed at a wide variety of flowers; they may defend small patches of flowers, but also visit flowering trees, which attract many hummingbirds of a variety of species.
