Illustration of Western Bluebird (Sialia mexicana)

The Western Bluebird is a jewel of open woodlands in the West, the male's deep cobalt-blue plumage offset by a chestnut breast and back. It depends on natural cavities and nest boxes for breeding and competes vigorously with European Starlings and House Sparrows for available sites. Nest box programs have helped stabilize declining populations.

Habitat
Open ponderosa pine woodlands, farms, and meadow edges
Diet
Insects, spiders, berries, and mistletoe berries
