Description
The black-chinned hummingbird is long. Adults are metallic green above and white below with green flanks. Their bill is long, straight and very slender. The adult male has a black face and chin, a glossy purple throat band and a dark forked tail. The female has a dark rounded tail with white tips and no throat patch; they are similar to female ruby-throated hummingbirds. Juvenile plumage is similar to that of adult females, but with buff margins on the dorsal feathers. Juvenile males may also possess purple feathers on their throats.[
Young are born almost featherless, but obtain a complete set of feathers within three weeks of hatching. Juveniles can begin replacing their plumage in November, and acquire their first basic plumage between April and May. Molts will then occur annually, taking 7–8 months at the population level.][
Similar species to the black-chinned hummingbird include broad-tailed hummingbird, rufous hummingbird, calliope hummingbird, Allen's hummingbird, lucifer hummingbird, Anna's hummingbird, and Costa's hummingbird.][

The males and females of this species use different habitats from one another for breeding territories.[ Black-chinned hummingbirds can exhibit territorial behavior around feeders as well as at other small feeding sites, and become more defensive as the breeding season continues. However, if there are a large number of individuals in an area as well as multiple food sources, this species will exhibit very little territoriality. Unlike most passerines, the agonistic call of the black-chinned hummingbird is acoustically complex, with notes ordered in non-random patterns, and are even more complex than their songs.][ This species also uses diving displays ( dives) for territory defense as well as courtship, producing a variety of tones as air passes through their feathers during the plunge.][
