The Green-Tailed Trainbearer species of hummingbird in the family Trochilidae.
It is a small hummingbird with males measuring about 7 inches long (including tail) and females, 4.3 inches.
It has emerald green upperparts, an iridescent green gorget that has a somewhat “flat or horizontal” bottom outline.
Underparts are green overall. Uppertail coverts and nearly half the uppertail are mostly emerald green.
Vent area is pale or greenish. Bill is black, relatively short, and nearly straight.
Females are a dull version of the male pale and speckled underparts and a shorter tail.
Their main diet consists of nectar. They seem to particularly favor lantana flowers.
Typically found at the edge of forests or shrubby woodlands, but also in drier and more open areas.
Occasionally visits feeders, but more often seen feeding at flowering shrubs.
