Sometimes treated as conspecific with C. seebohmi. Race canturians has been considered a separate species on basis of differences in plumage and voice; further study, including DNA analysis, required. Birds from S Kuril Is described as race viridis, considered synonymous with sakhalinensis. Borodino Is race restricta (rich rufous-brown above, greyish-olive wash on breast side to undertail-coverts) extinct. Six extant subspecies recognized.
