Taxonomy
Based on a review in 1961, R. t. caboti (Labrador Caribou), R. t. osborni (Osborn's Caribou—from British Columbia) and R. t. terraenovae (Newfoundland Caribou) were considered invalid and included in R. t. caribou. Some recent authorities have considered them all valid, even suggesting that they are quite distinct. An analysis of mtDNA in 2005 found differences between the caribous from Newfoundland, Labrador, south-western Canada and south-eastern Canada, but maintained all in R. t caribou.
