Ed, I wouldn’t doubt if they were like Fox Sparrows, in which our wintering birds are from farther north, and the Cascades breeders winter south of us.
But to quote a greater authority, Birds of the World Says that the Cascades-breeding Catharus guttatus slevini winters from s. Nevada and se. Arizona south into northern Mexico. The subspecies C. g. oromelus that breeds in the mountains farther east in the state also winters well to the south. The only subspecies reported wintering in the lowlands of the Pacific Northwest are C. g. guttatus and C. g. nanus that breed in southern coastal Alaska and northern coastal BC.
