Possibly forms a clade with A. pratensis, A. roseatus, A. spinoletta, A. petrosus and A. rubescens. Birds from W Eurasia (E to Taymyr Peninsula) average slightly larger and show more contrasting plumage, thus sometimes recognized as race rufogularis; variation, however, apparently clinal. Monotypic.
N Holarctic, mostly N of Arctic Circle, in narrow band from N Fennoscandia E to NE Russia (Chukotskiy Peninsula, S to Kamchatka, Commander Is and N Kuril Is) and extreme NW USA (W Alaska). Winters predominantly in Africa (mostly S of Sahara) and SE Asia.
