Distribution map of Amazilia cuanura


This species can be found in Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.[1][3]


Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest. These hummingbirds can be found in humid and dry oak or pine forests, in open woodlands and in coffee plantations, at altitudes of 3,300 feet or lower.[4]


Amazilia cyanura feed on nectar of many flowers, but especially of Inga flowers.[4] It is also an agile flycatcher.[5]


Amazilia cyanura can reach a length of 9–10 millimetres (0.35–0.39 in). These hummingbirds show a metallic deep green plumage, a characteristic deep blue tail and in proper lighting chestnut or rufous wings. Rump and uppertail coverts are purplish. The bill is black. Females are duller than males and have a grayish belly, and less rufous wings. This species is very similar to Steely-vented Hummingbirds (Amazilia saucerrottei) and to Berylline Hummingbird (Amazilia beryllina).[4]
