Female: similar to male, but paler with a nearly gray head, chest and white belly Juvenile: similar to adult of the same sex Nest: cavity, old woodpecker cavity, wooden nest box; female builds; 1-2 broods per year Eggs: 4-6; pale blue without markings Incubation: 13-14 days; female incubates Fledging: 22-23 days; female and male feed young Migration: partial migrator to non-migrator in Oregon Food: insects Compare: Similar to Western Bluebird (pg. 57), but not as dark blue and lacks Western's rusty red chest. Stan’s Notes: Common in open ainous country, nesting on the eastern two-thirds of the state. Due to conservation of suitable nest sites (dead trees with cavities and man-made nest boxes), populations have increased dramatically. Like the other bluebirds, ain Bluebirds take well to nest boxes and will tolerate close contact with humans. Young will imprint on their first nest box or cavity, then choose a similar type of box or cavity throughout the rest of life. Read more ( javascript:void(0) )
