Blue-headed Hummingbird

The blue-headed hummingbird is a hummingbird of the genus Riccordia. It is exclusively found on the islands of Dominica and Martinique in the Lesser Antilles in forests along rivers. The males and females have distinct appearances; the female has a white front, and her back and wings are iridescent bronze-green colored. The male is entirely emerald of varying shades, with an especially blue head. The blue-headed hummingbird's behavior is typical of most hummingbirds, mostly feeding off of nectar. It nests from February to May in tree ferns, incubating a clutch of two white eggs for 16 to 18 days. It is a near-threatened species, with an estimated mature population of 25,000–150,000.
