Black-crested coquette

Description

The black-crested coquette (Lophornis helenae) is a species of hummingbird in the family Trochilidae. It is found in Belize, Costa Rica, Guatemala, Honduras, Mexico, and Nicaragua. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest. The black-crested coquette is 6.3 to 7.7 cm (2.5 to 3.0 in) long with an average weight of 2.6 to 2.8 g (0.092 to 0.099 oz). The adult male has a dark metallic green crown with a wispy greenish black crest. The nape and back are metallic bronze green; a white band separates the back from the sooty blackish rump and uppertail coverts. The central tail feathers are dull greenish bronze between their cinnamon rufous bases and dusky ends. The outer tail feathers are cinnamon rufous. The chin and upper throat are metallic yellowish green with a velvety black band below. The sides of the throat have tufts of buff feathers with velvety black margins. The breast is metallic bronze, the belly and flanks white with metallic bronze spots, and the undertail coverts cinnamon rufous. Its bill is bright red with a black tip. The adult female has dark metallic green to bronze green upperparts with a narrow white band across the rump. Its crown is plain, without the male's crest. The lower rump and uppertail coverts are black with a bronze gloss. The central tail feathers are olive bronzy between cinnamon rufous bases and blackish ends. The outer tail feathers are cinnamon rufous with a wide black band near the end. The face is black. The chin and throat vary widely from pale grayish buff to cinnamon tones and lack the male's tufts. The breast is metallic bronze, the belly white with metallic bronze spots, and the undertail coverts cinnamon rufous. Its maxilla is black and the mandible red with a dark tip. Immature males resemble the adult female but with a smaller crest than the adult's and a whitish throat with a small black "apron". Immature females resemble the adults. The black-crested coquette is found from southern Veracruz in Mexico south through eastern Guatemala, southern Belize, and eastern Honduras and Nicaragua into eastern Costa Rica. A separate population is on the Pacific side of Central America from Chiapas in Mexico south through much of western Guatemala. The species inhabits semi-open landscapes at the edges of humid montane and lowland evergreen forests. It also occurs in gaps in the forest and brushy areas.
