Allen's Hummingbird illustration or species image

Allen's Hummingbird breeds in a very narrow range along the California and southern Oregon Coast, yet is very common in much of this range in the summer months. Strongly migratory, Allen's Hummingbirds nearly all depart for Mexico for the summer months. They are very closely related to the Rufous Hummingbird, and are quite difficult to tell apart. While not nearly as apt to wander widely as the Rufous Hummingbird, strays of Allen's Hummingbirds have been found well east of their normal range, primarily along the Gulf Coast.

Habitat

In their summer range along the U.S. West Coast, Allen's Hummingbirds can be found in and around coastal forests and the surrounding shrublands. Their wintering grounds in Mexico are primarily foothill and mountain forests.

Diet

Typical diet of hummingbirds, primarily nectar, but insects also comprise a portion of the diet.

Behavior

Aggressive as are many hummingbird species. Nesting areas and feeding areas are both vigorously defended from other hummingbirds, and other intruders.

Nesting

The nest is built of plant down and fibers with an outer layer of leaves, decorated with lichens and bits of bark held in place with spiderwebs. The female alone builds the nest, incubates the eggs, and takes care of the young.

Song

The “song” of a male Allen's Hummingbird is produced with a high-pitched metallic whistle created by the wings when the male dives during courtship.

Migration

Allen's Hummingbirds are strongly migratory. They move to their summer range along the western U.S. coast in mid- to late winter and early spring. They winter in a small area in Mexico.

Feeders

Will attend hummingbird feeders.

Similar Species

Extremely similar to Rufous Hummingbird.

Conservation Status

Allen's Hummingbirds have adapted fairly well to human activity in their normal range, although local declines have undoubtedly occurred where habitat loss has been extensive.
