J. F. Gmelin, 1788,
Has been considered to belong to the B. bubo species-group (see that species, below). Formerly included B. magellanicus as a race, but DNA, voice and morphology found to differ. N populations lagophonus and heterocnemis possibly not separable from saturatus, and perhaps better merged with latter. Boundaries of races often obscure, and problem further complicated by birds of intermediate appearance; pacificus and pallescens intergrade in California. Numerous geographical races named, many poorly differentiated, or apparently result of individual variation, or of wandering individuals from other parts of range: forms described from C Canada (scalariventris), Venezuela (scotinus), E Colombia (elutus) and C Colombia (colombianus) considered not acceptable; also, name occidentalis, used for birds from Rocky Mts of WC Canada to WC USA, now synonymized with subarcticus; older name wapacuthu formerly applied to populations of W & C Canada and N USA (limits uncertain), but validity questioned as it cannot be certainly associated with present species#R. Fifteen races tentatively recognized.
Introduced (nominate race) to S Marquesas Is (Hiva Oa), in S Pacific.
