group of youngsters perching on cliff
Young Rocky Mountain Bighorn Sheep perched on a cliff in Jasper National Park, Alberta, Canada. Bighorn Sheep can scale cliff faces that appear to be almost vertical. While the cliffs often look perilous to human observers, Bighorns actually depend on the cliffs for protection from predators. Bighorn Sheep are known for their breeding contests. During the rutting season, male bighorns compete for mates with spectactular horn crashing charges: They rear up on their hind legs, charge toward each other and bang their huge horns together with a loud crack. Diseases of domestic sheep are adversely affecting some bighorn populations.
