Desert bighorn sheep is a subspecies of bighorn sheep that is native to the deserts of the United States’ intermountain west and southwestern regions, as well as northwestern Mexico. They are commonly seen on steep terrain and cliffs such as canyons. They live throughout the American Southwest including the Grand Canyon, Mojave Desert, and Sonoran Desert.
This species is highly adapted for desert climate to both hot and cold weather. They can go for extended periods without drinking for up to weeks or months at a time. They sustain their body moisture from food and rainwater collected in temporary rock pools and often rest in the shade of trees and caves during the heat of the day.
