Type of Residency: Year-round

Global Range: BREEDING: southwestern Oregon, eastern Washington, to southern Idaho, southwestern Wyoming, Colorado, New Mexico, northern and central Texas, and sometimes Oklahoma, to Baja California and mainland of Mexico. NON-BREEDING: northern Baja California, southeastern California, central Arizona, south into mainland of Mexico, El Salvador, casually to Costa Rica (Terres 1980).

Weight: 27 grams

Systems

• Terrestrial
• Freshwater

Comments: Desert scrub, pinyon-juniper and oak woodland, chaparral, thorn scrub and riparian woodland; in winter also in open deciduous woodland (AOU 1983). Usually nests in a tree cavity, a hole in a cactus, in an abandoned woodpecker hole or Cactus Wren nest (Harrison 1978).

Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.

Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.

A long-distance migrant in most of the U.S. range. Resident throughout the year in southeastern California, central Arizona, and parts of Mexico.

Comments: Primarily insectivorous; feeds on bees, wasps, ants, caterpillars, moths, grasshoppers, etc. Also known to eat spiders and some berries. Often forages by flying out from perch and catching insects in the air.

Maximum longevity: 11 years (wild)

Clutch size 3-7 (usually 4-5). Incubation by female, about 15 days. Altricial young tended by both parents, leave nest in 16-17 days.

Comments: North American Breeding Bird Survey data indicate a significant population increase in western North America, 1966-1989 (Droege and Sauer 1990, Sauer and Droege 1992).

Restoration Potential: See Mitchell (1988) for specifications for the construction and placement of nest boxes.
