.

Has been considered conspecific with P. cinctus and P. rufescens. Geographical variation slight, and confused by seasonal and individual variation, although genetic study found evidence of W & E clades, originally isolated in separate refugia#R; other named races, based on very slight differences, include cascadensis (Cascade Mts, on W Canada–USA border), merged with columbianus, and rabbittsi (Newfoundland, in E Canada), synonymized with nominate. Full review of all races required. Five subspecies recognized.
