Records generalized to full township/ranges; true population density thus much thinner than symbolized. Uncommon in mature coniferous forests in Cascades. Most common in Kittitas County forest zones, with a few mid- to high-elevation records from King County. Confirmed nest in extreme southwestern Kitsap County in 1991 represents only record from four-county area west of Puget Sound. Species has declined precipitously in historic times due to unfavorable logging practices and intolerance of human presence near nest sites. Absent as breeder from developed lowlands, where extremely rare even as migrant.
