Antlers are carried by both sexes. Caribou generally form small herds. Lichens are an important food source but grasses, broad-leaved plants and twigs are also included in their diet. Caribou are often sighted along the Icefields Parkway south from Sunwapta Falls and along the Maligne Road. There are about 3000 living here.
Bighorns have a sandy coloured coat and a white rump patch.
Bighorns are primarily grazers and migrate seasonally between low grassy slopes and alpine meadows. Escape terrain with rocky ledges is usually nearby. Sheep are very gregarious and form mixed herds in winter and segregated herds in summer. During the mating season in the autumn, the rams battle for dominance by crashing horns together until the weaker animal gives up. Horn tips are often broken during these battles.
