A ram is a male sheep—the slang term being “buck.” Rams are always full-grown males and generally have the same characteristics and diet as other sheep, but they differ in terms of the habitat in which they live. Most species of rams are wild; however, many are also domesticated and kept on farms.
Rams are famous for their large, curled horns. The larger their horns, the better, since the horns serve as a symbol of status and are used as a weapon when battling other rams over mating rights. The weight of a typical ram is about 117 to 279 lbs. (53 to 127 kg). The shoulder height is around 32 to 40 inches. A ram has very good eyesight, which is mainly used for observing the surrounding areas for predators.
A Rocky Mountain bighorn ram’s horns can weigh 30 pounds (14 kilograms)—more than all the bones in his body combined. Females (ewes) also have horns, but they are of smaller size.
Rocky Mountain bighorns inhabit the mountains from Canada south to New Mexico. They are relatives of goats, and have balance-aiding split hooves and rough hoof bottoms for natural grip. These attributes, along with keen vision, help them move easily about rocky, rugged mountain terrain.
