Gardens, chaparral, open woods.
Found in a wide variety of habitats within its range, including streamside groves, chaparral, open oak woodland, coastal sage scrub, arid brush, gardens, city parks. Most common in lowlands and lower slopes, but may be found in high mountain meadows in l
ate summer.


Can begin ne
sting in December. In courtship display, male hovers in midair, giving buzzy song, then flies much higher; he then dives steeply and rapidly toward the female, giving a loud explosive popping sound at bottom of dive. Also buzzes back and forth in front of
perched female in short shuttling flights.
Nest: Site varies, usually on branch of tree or shrub, sometimes in vines, on wires, under eaves. Usually 4-25′ above ground. Nest (built by female) is a cup of plant fibers and spider webs, lined with fine plant
down and sometimes feathers, the outside camouflaged with lichens. Female may continue building after eggs are laid.
Eggs: 2, rarely 1-3. White. Incubation is by female only, 14-19 days.
Young: Female feeds young by inserting long bill in open mouth of young, then regurgitating insects, nectar. Age of young at first flight about 18-23 days.

Feeding habits

Mostly nectar and small insects. F
eeds on nectar from flowers. Uses a wide variety of flowers, including tubular red ones of “classic” hummingbird type, also many others. Also takes sugar-water and oozing sap. Eats many small insects and spiders.
Takes nectar while hovering in front of flowers; will also perch to feed if perch is convenient. Regularly visits feeders filled with sugar-water. Will visit holes made in bark by sapsuckers to drink oozing sap. Catches insects in midair or takes them fr
om foliage.


This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Annas Hummingbird status Least Concern


Southwestern British Columbia, western United States to northwestern Mexico. Migration: Southwestern birds perform some east-west migration, many Arizona birds m
oving west to California in mid-spring after nesting, returning in late summer. Others are permanent residents. Sometimes wanders far north or east of usual range.
