Desert Bighorn Sheep
Nevada’s state mammal turns steep desert rock into refuge, using gripping hooves while tracking sparse forage, shade, and water across isolated ranges.

Desert bighorn are smaller and paler than many Rocky Mountain bighorn. Each cloven hoof combines a hard rim with a softer gripping pad, helping sheep cross slopes that slow predators. Rams carry massive curls; ewes have slimmer horns. Their diet shifts from grasses and flowering forbs after moisture to shrubs, cacti, and tougher browse as the desert dries.
Desert adaptation does not eliminate the need for water: Summer movements often center on springs, seeps, and wildlife guzzlers. Glass shaded ledges and water approaches around dawn, or watch the unusually visible Boulder City herd from a respectful distance. Never feed, crowd, or block sheep, and keep dogs well away; domestic sheep and goats can transmit respiratory disease to wild herds.

Recognize and observe
- Recognize
- Begin with combine the white rump, heavy body, horns, and cliff habitat when identifying Desert Bighorn Sheep.
- Find them
- Look for glass shaded ledges and water approaches at cool hours together with binoculars from below, outside the travel line before accepting the identification.
- Read movement
- Broken desert mountains, cliffs, talus, canyons, washes, and nearby seasonal or artificial water sources; visible year-round.
- Protect
- Never feed, corner, follow to water, or allow dog contact.
Good to know
Boulder City’s visible herd is still wild. Keep routes to shade and water open, secure food, keep dogs far away, and report sick or dead sheep to NDOW rather than approaching.
Notice these
- White rump patch
- Compact pale body
- Confident cliff movement
