Caribou are likely to be sighted throughout the journey. The timing of the migration varies from year to year, but it is almost certain that caribou will be seen on this river trip. The animals located along the Coppermine River are part of the Bluenose herd, whose population is estimated to be in the range of 68,000 animals. There is a sizeable population of muskoxen in the Coppermine River area and it is prime grizzly bear habitat. The bears here are slightly smaller (males average around 200 kg) than the bears of the west coast of Canada and Alaska. A number of arctic wolf packs work the Coppermine River Valley, many which follow the caribou migration.
