This species was uncommon in low- to moderate-elevation, mid- to late-seral pine and Douglas-fir forests of the east Cascades, Okanogan and Methow valleys, and the western Blue Mountains. However, they were common in the eastern Blue Mountains at all elevation, and in the Okanogan Highlands.
The core areas of use were Ponderosa Pine, Interior Douglas-fir, and Grand Fir. Peripheral areas of use were in the Sub-alpine Fir zone, except in the Blue Mountains, where this zone was core. Good habitats were conifer-lined rivers and conifer forests, except those explicitly labeled as early seral.
Washington breeders represent the nominate western subspecies S. r. thyroideus. Despite the preponderance of data for this species from the eastern Cascades and eastern Okanogan valley, they are actually more common in the Okanogan Highlands region and the eastern Blue Mountains. It is rarer in the western Blue Mountains (where rainfall is higher and forests are more closed), than in the eastern Blues. The first reported sight record for this species was in northeastern Washington in Ferry County. Apparently Western Larch must be a component of forests that support Williamson's Sapsucker.
