The Green-backed Firecrown (Sephanoides sephaniodes) is a hummingbird that is found in Argentina and Chile. It can be fairly common in some locations, especially the Robinson Crusoe Island, 350 miles off the Chilean coast. It is found as far south as Tierra del Fuego.
Like its cousin the Juan Fernandez Firecrown, the Green-back often hangs from flower petals or leaves with its feet. Their nests are built in high branches or bushes. They like to eat insects, inch worms, and nectar from flowers.
