Blue-headed hummingbird

The blue-headed hummingbird (Riccordia bicolor) 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 frontside, and her backside and wings are iridescent bronze-green colored. The male is entirely emerald of varying shades, with an especially blue head, as his name suggests. Its behavior is typical of most hummingbirds, mostly feeding off of nectar. It nests from February to May in tree ferns, incubating a clutch of 2 white eggs for 16 to 18 days. It is a near-threatened species, with an estimated mature population of 25 to 150 thousand.
