Identifying Them:

Females are a light green-gold color and have a pink-purple coloring on their necks. Males’ bodies and wings are more of a darker green-gold color, and their head is almost entirely (not just their neck) pink-purple, as seen in the picture above. These birds are medium-sized compared to other hummingbirds. Both males and females are about the same height, with a length of 3-4 inches tall, and with wingspans of between 4 and 5 inches.


These hummingbirds are found in a large variety of habitats in both urban and suburban areas, like gardens, open-woodlands, and chaparral.


During courtship, the male flies up above 100 feet in the air, then dives making a loud, high-pitched noise at the bottom of the dive called the “dive noise.” Besides the “dive noise,” they have many calls that include various of buzzes, chips, and chatters. Both genders defend territories, although males do it for a longer period of time.

Nesting and Nestlings:

Females choose where the nest is made, which is usually on a branch, not too high off the ground (occasionally near a source of nectar). The nests are often built in oak, eucalyptus, or sycamore trees, but she also builds nests on shrubs and sometimes, poison oak. Females make the nest, which is made of feathers and thistle, and is bound together by spider silk. It usually takes about a week to complete the nest, which is about an inch high and an inch and a half in diameter.

Females have about 2-3 broods (about 2 eggs per each brood). The eggs are just white with no specks or other coloring, and she incubates them for about 20 days (3 weeks). The females feed their nestlings by sticking her long bill deep into their mouths and regurgitating insects that are sometimes mixed with nectar. About 2-3 weeks after they hatch they become fledglings and have their first flight.


Anna’s Hummingbirds eat mostly just insects and nectar found in flowers or sugar-water found in hummingbird-feeders.
