Physical Characteristics:

Rocky Mountain Bighorn Sheep is one of the largest wild sheep species in North America, with mature rams weighing up to 250 pounds and ewes weighing up to 150 pounds.

They are named for their large curved horns, which can grow up to three feet in length in mature rams. The horns are an important part of the sheep’s defense against predators and are used for fighting during the mating season.

The bighorn sheep has a distinctive brown or tan coat, with a white rump patch and a darker brown muzzle. Both males and females have horns, but the females’ horns are shorter and less curved than the males’.

The sheep’s hooves are designed to grip rocky terrain, making it easier for them to climb steep slopes and navigate rugged mountain terrain.


The Rocky Mountain Bighorn Sheep is native to the western United States and Canada, with the largest populations in Colorado, Montana, and Wyoming. These sheep prefer to live in high-altitude mountain ranges, above the treeline, where they can easily navigate the rocky terrain and escape predators.

Bighorn sheep have a unique ability to acclimate to high-altitude environments, which allows them to live at elevations of up to 14,000 feet. During the winter months, they move to lower elevations to find food and avoid deep snow, but they return to their high-altitude habitats in the spring and summer months.


Rocky Mountain Bighorn Sheep are social animals, living in herds of up to 100 individuals. Herds are usually composed of ewes, lambs, and young rams, with mature rams living separately in small bachelor groups. During the mating season, known as the rut, mature rams compete for the opportunity to mate with females. They engage in dramatic displays of dominance, including head-butting and horn clashing.

Bighorn sheep are primarily herbivores, feeding on grasses, shrubs, and other vegetation found in their mountainous habitats. They have a unique digestive system that allows them to extract nutrients from tough, fibrous plant materials.


Rocky Mountain Bighorn Sheep populations were once threatened by overhunting and habitat loss, but conservation efforts have helped to increase their numbers in recent years.

The Colorado Division of Parks and Wildlife has implemented a number of measures to protect bighorn sheep populations, including limits on hunting, habitat restoration, and disease prevention programs.

One of the biggest threats to bighorn sheep populations is disease, particularly from domestic sheep and goats, which can transmit deadly respiratory illnesses to their wild counterparts.

The Colorado Division of Parks and Wildlife has taken steps to prevent contact between domestic and wild sheep populations, including grazing restrictions and fencing.
