Firecrown
The firecrowns are the genus Sephanoides of the hummingbirds. There are two species. The green-backed firecrown occurs widely in  Argentina and Chile, but the Juan Fernández firecrown is found solely on Isla Róbinson Crusoe, one of a three-island archipelago belonging to Chile. Both species will hang from flower petals or leaves with their feet. They feed on nectar and insects
