Dall Sheep

Dall sheep or thinhorn sheep, Ovis dalli, is a species of wild sheep native to northwestern North America. They live in mountainous alpine habitats across northwestern British Columbia, the Yukon, the Northwest Territories and Alaska. They browse a variety of plants, such as grasses, sedges and even shrubs such as willow, during different times of the year, and acquire minerals to supplement their diet from mineral licks. Like other Ovis species, the rams engage in dominance contests with their horns. The specific name honours the American naturalist William Healey Dall. Two subspecies are recognised, the nominate Dall's sheep and the Stone sheep, which were once distinguished by fur colour, though colour intergradation is complete.
