The Dall Sheep is native to northwestern North America and in Alaska can be found in all of the subarctic mountain ranges. The males have heavy curled horns that at maturity often complete or surpass a full 360 degrees of growth. The females have much smaller horns that may only be a few inches long. Coloration ranges from slate gray to white and depends on the genetics of local breeding stocks. Interestingly, the most dangerous predator for Dall Sheep young is the Bald Eagle, which will make off with the lambs given half a chance.
