Anna's Hummingbirds are found in chaparral, open woodlands and gardens of western North America.


Anna's Hummingbirds feed on nectar, tree sap and small insects.


During the breeding season males perform remarkable courtship displays which involve them flying high into the air and making elaborate dives to attract a mate. During these dives they produce a loud sound with their outer tail feathers.

Female Anna's Hummingbirds build a tiny, woven, cup shaped nest from small twigs, lichen and mosses. The nest is lined with downy feathers or plant material and it is held together with spider silk. 1 - 3 white eggs are laid and the female will incubate them for 14 - 19 days.


Predators of Anna's Hummingbirds include other birds such as scrub jays and american kestrels.
