Common breeder in most forested zones in King and Kittitas Counties. May be found nesting in wide variety of habitats from sea level to at least 5,000 feet elevation as long as suitable cavities available, including dead trees and chimneys. Spottily distributed in developed King County lowlands, mostly near rivers and freshwater lakes. Rare on Vashon Island and in Kitsap and Island Counties. Local in Kittitas Valley near Yakima River. Apparently absent from Wenatchee Mountains above ponderosa pine zone and below subalpine fir zone, contra predicted range in Washington Gap report (Smith et al. 1997).
