Bighorn Sheep

Ovis canadensis

The bighorn sheep (Ovis canadensis) is a wild mountain sheep of western North America, recognized by the massive curled horns of mature rams and the smaller horns of ewes. Different populations occupy rocky mountains, desert ranges, and canyon country, with coats and body size varying by region. Bighorns are agile climbers that use steep escape terrain, open sightlines, and seasonal movements between lambing areas, mineral sources, and winter or summer range.

Bighorn sheep management is centered on conservation herds, public lands, and specialized zoo care. Wildlife agencies use surveys, translocations, hunting quotas, and habitat work to maintain populations, while trying to reduce contact with domestic sheep and goats that can transmit respiratory disease. Captures and releases require low-stress handling because these animals are strong but vulnerable to injury and overheating. In managed facilities, rockwork, secure slopes, browse, and hoof wear are practical concerns. For landowners near bighorn range, fencing, water developments, and livestock decisions can influence whether wild herds remain healthy.
