About These Birds
Short-tailed Emerald
A small hummingbird (7-8 cm) found in Andean cloud forests from Colombia to Venezuela at 1,500-2,800 m. Green plumage with a notably short tail. Nectarivore of montane forest undergrowth and edges. Named for its unusually short tail for an emerald.
Sword-billed Hummingbird
