Émeraude d'Olivares Chlorostilbon olivaresi

Poorly known hummingbird found only in the remote Chiribiquete Mountains in southeastern Colombia, far from the Andes. Male is iridescent green with a bluish tail. Female has pale underparts, black mask, and white stripe behind the eye. Very similar to the widespread Blue-tailed Emerald, but larger and longer billed. Inhabits scrubby areas in the higher parts of the mountains, and avoids dense forest.
