Small, compact, short-billed and short-tailed hummingbird with green tail. Male all glittering green; female green above and gray below with dark cheek, white eyeline, and white-tipped tail. Occurs in dry to humid forest borders in montane regions (no higher than 2500 m), usually in gardens and cultivated areas. Often perched alone near small flowers at mid-height. Very similar to other emeralds; distinguished from both male and female Blue-tailed Emerald by green tail; from Short-tailed Emerald by having wings and tail the same length when perched; and from male Narrow-tailed Emerald by uniform length tail feathers. Endemic to the Andes and Coastal Cordillera of Venezuela.
