Stanovoy Mountains and shores of Sea of Okhotsk, south-east Russia.
Scientific name of this species has been given variously as urogalloides or parvirostris, but former is correct#R. Closely related to T. urogallus, with which it frequently hybridizes in limited areas of overlap in basin of R Yenisey. Subspecies name kamtschaticus sometimes spelt erroneously as kamschaticus, but former spelling is the correct original one. Some authors subsume stegmanni within nominate. Birds from various parts of Siberia formerly awarded races turensis (from lower R Tura), janensis (Verkhoyansk) and kolymensis (R Kolyma region), those on Sakhalin I race sachalinensis, and those from Transbaikalia race macrurus; plumage details of this species, however, subject to both clinal and individual variation#R and none of these is regarded as acceptable. Three subspecies currently recognized.
