Stunning and rather large hummingbird, found only on Robinson Crusoe Island in the Juan Fernandez archipelago. Locally fairly common in gardens, forest edges, native scrub, and groves of non-native Eucalyptus trees. Male is bright rusty orange overall with iridescent “firecrown” and an amazing song. Female looks very different: green above with a blue crown and flashy white tail sides, and white below with blue-green spotting. Smaller and very differently plumaged Green-backed Firecrown also occurs in same areas.
