The Versicolored Emerald is a hummingbird of central and eastern South America, using forest edges, gallery woodland, and other open habitats. It feeds on nectar and small insects. Plumage varies substantially, so tail pattern is useful alongside throat and forehead color.
It is about 8.5 cm long. The gray tail has a dark subterminal band and pale tip. The plumage is green, the throat shines with bluish iridescence, and the white belly extends onto the breast. Green or white on the forehead and throat varies.
It occurs at wet-forest edges, dry woodland, gallery forest, secondary growth, mangroves, várzea edges, farms, and towns. It takes nectar and small insects. The sources show a broad habitat range rather than dependence on one forest type.
