It sometimes includes the similar-looking Porcupine caribou, in which case the barren-ground caribou is also found in Alaska.[1][2] The barren-ground caribou is a medium-sized caribou, smaller and lighter-coloured[3] than the boreal woodland caribou, with the females weighing around 90 kg (200 lb) and the males around 150 kg (330 lb). However, on some of the smaller islands, the average weight may be less. The large migratory herds of barren-ground caribou take their names from the traditional calving grounds, such as the Ahiak herd, the Baffin Island herds, the Bathurst herd, the Beverly herd (Beverly Lake in western Nunavut),[4] the Bluenose East herd (southwest of Kugluktuk),[5] the Bluenose West herd, the Porcupine herd and the Qamanirjuaq herd.[6]
