what is it?

The thinhorn sheep ( Ovis dalli ) is a species of sheep native to northwestern North America, ranging from white to slate brown in colour and having curved, yellowish-brown horns. The two subspecies are the nominate Dall sheep or Dall's sheep and the more southern subspecies, Stone sheep (also spelled Stone's sheep) ( O. d. stonei ), which is a slate brown with some white patches on the rump and inside the hind legs.
