The firecrowns are the genus Sephanoides of the hummingbirds.
There are two species.[1]
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
