Allen's Hummingbird

Has adapted fairly well to suburban habitats, but surveys still show decreasing populations in recent decades.
Family Hummingbirds
Habitat Brushy canyons, parks, gardens. Breeds in a variety of semi-open habitats, including open oak woods, streamside groves, well-wooded suburbs, city parks. Winters mostly in foothills and mountain forests in Mexico. Migrants also occur in high mountain meadows in late summer.
A close relative of the Rufous Hummingbird, Allen's has a more limited range, nesting mostly in California. This is one of the two common nesting hummingbirds in northern California gardens (Anna's is the other). Females and immatures of Allen's Hummingbird are almost impossible to separate from Rufous females without close examination, so the status of the species in migration is still being worked out by dedicated hummingbird banders.
