The Western Bluebird (Sialia mexicana) in summer is found in western North America from southern British Columbia south to central Mexico, east to western Montana and west Texas, but absent from Great Basin. The winter range is in lower elevations in much of breeding range. Also winters outside breeding range in central California and along the lower Colorado River. Unlike other bluebirds, the Western Bluebird prefers open woodland habitat where in summer it forages for insects, hunting from perches and dropping to its prey on the ground. Winter food includes fruit and seeds. The nest is in cavities in trees and snags, or between bark and trunk and is made of woven dry grasses, straw, conifer needles, fur, string, or cedar bark strips. May also use nest boxes. |
