Other common names: Hudsonian/Acadian/Brown-capped Chickadee

Until recently present genus normally subsumed into a broad Parus, and many authors still prefer that treatment. Genus normally treated as feminine, but no evidence in original description or elsewhere justifies this, so genus is masculine by default. Forms a superspecies, and has been considered conspecific, with P. cinctus and P. rufescens. Geographical variation slight, and confused by seasonal and individual variation; additional named races, based on very slight differences, include cascadensis (Cascade Mts, in extreme S British Columbia and extreme N Washingt..

Geographical variation slight, and confused by seasonal and individual variation; additional named races, based on very slight differences, include cascadensis (Cascade Mts, in extreme S British Columbia and extreme N Washington, on SW Canada-USA border), merged with columbianus, and rabbittsi (described from Newfoundland, in E Canada), synonymized with nominate. Full review of fresh-plumaged individuals of all races required. Five subspecies currently recognized.
