North America = South Carolina, USA.
Closely related to S. nuchalis and S. ruber; sometimes treated as conspecific with former, interbreeding with it to limited extent in SW Canada (Alberta), and in the past sometimes considered conspecific also with latter, the two more rarely hybridizing where ranges overlap. Birds from S Appalachian Mts sometimes separated as race appalachiensis on basis of slightly darker plumage and marginally smaller size, but considerable overlap with N populations and subspecific recognition considered unwarranted. Monotypic.
E Alaska, S Yukon, SW Northwest Territories and NE British Columbia E across Canada to NC Ontario and Newfoundland, and S to C Alberta and C & E USA (to E South Dakota, N Iowa and Appalachians). Winters SE USA (S from about S Kansas, S Ohio and Connecticut) S to Panama.
