Similar Species

In East, female difficult to distinguish in field from female Ruby-throated Hummingbird. Structure like Ruby-throated: slender, small-headed, and thin-necked. Female distinguished from similar species by overall shape, long bill, flat forehead, drab greyish colour and longer wings with distinct club shaped primaries.

Breeds from British Columbia south throughout West to Mexico and central Texas.
Winters in Mexico, though a small number of Black-chinned winter along the Gulf Coast of the USA.


This is a monotypic species[1].


Mountain and alpine meadows, woodlands, canyons with thickets, chaparral, and orchards.



Their main diet consists of flower nectar, small insects and spiders. They will come to feeding stations for sugar water.

Two white eggs in a nest of fluffy plant wool and lichens woven together with spider webs, placed in a shrub or low tree.

The male Black-chinned, like all hummingbirds, maintains a mating and feeding territory in spring. He courts his female with a dazzling aerial display involving a pendulum-like flight pattern. When mating interest wanes, the male often takes up residence elsewhere, near a good food supply. Later, when plant blooming and insect swarming subside, the birds move south.


Voice: A low tup.
