Barren-ground caribou

The barren-ground caribou (Rangifer tarandus groenlandicus; but subject to a recent taxonomic revision. See Reindeer: Taxonomy.) is a subspecies of the reindeer (or the caribou in North America) that is found in the Canadian territories of Nunavut and the Northwest Territories, in northern Alaska and in south-western, Greenland. It includes the Porcupine caribou of Yukon and Alaska. The barren-ground caribou is a medium-sized caribou, smaller and lighter-colored 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), the Bluenose East herd (southwest of Kugluktuk), the Bluenose West herd, the Porcupine herd and the Qamanirjuaq herd.
