Western Bluebird Nest-site Characteristics in Managed Ponderosa Pine Forests
We studied the nest-site characteristics of Western Bluebirds nesting in natural tree cavities in burned and unburned logged ponderosa pine forests along the east-slope of the Cascade Range of Washington, 2003–2008 and 2010. We compared 13 bluebird nest-site habitat variables between burned and unburned stands by assessing overlap in 95% CI.
Western Bluebird Nest Survival in Managed Ponderosa Pine Forests
The Western Bluebird (Sialia mexicana) is a secondary-cavity-nesting thrush that breeds in semi-open habitats throughout much of western North America. Historically, the Western Bluebird was more common in Washington west of the Cascade crest than to the east, but today it is more abundant in the eastern Cascades.
