Last Ram Standing: Bighorn Sheep

In the Rocky Mountains of North America, where 3,000-meter class peaks tower across the range, bighorn sheep gracefully leap across death-defying cliffs. The males, or rams, display massive curved horns that can weigh up to 14 kilograms. As winter approaches, rams gather in a large group to clash their horns against one another, to determine who is strongest. The victorious alpha male dominates the flock of female sheep, and the defeated rams must obey. The relentless contests leave the rams exhausted, making some vulnerable to predation by bears and wolves. An intimate look into the vigorous, little known lives of the bighorn sheep in the wintry Rockies.
