In past, sometimes considered conspecific with all three congeners. Often lumped with C. antarctica, but mitochondrial DNA, plumage and biometrics all suggest they are separate species. Monotypic.

Distribution:

Iceland, Faeroes, N Scotland, Jan Mayen, Svalbard, Bear I, Norway and NW Russia (Kola Peninsula, Novaya Zemlya and neighbouring Vaygach I). Winters predominantly off Iberia and NW Africa, south to N Senegal; smaller numbers winter on the Grand Banks of Newfoundland. Occasional juveniles move as far S as the Cape Verde Is and Brazil.
