Bighorn Sheep

Bighorn males, called rams, are famous for their large, curled horns. These impressive growths are a symbol of status and a weapon used in epic battles across the Rocky Mountains.

Fighting for dominance or mating rights, males face each other, rear up on their hind legs, and hurl themselves at each other in charges of some 20 miles an hour. The resounding clash of horns can be heard echoing through the mountains as the confrontation is repeated—sometimes for many hours—until one ram submits and walks away. The animal's thick, bony skull usually prevents serious injury.
