File:Desert Bighorn Sheep in Grand Canyon National Park D 3939 (5735086801).jpg

Among the largest hoofed mammals in the park, the desert bighorn sheep, Ovis canadensis, are relatively scarce along the rim, preferring the rocky slopes and side canyons of the inner canyon. These animals roam the entire depth of the canyon from the rims to the Colorado River,

foraging on plants and negotiating the steep, rocky terrain with ease. They do not shed the long, curved horns that continue to grow throughout their lives. Like many mammals of the region, they are likely to be found near reliable sources of water: springs, seeps, or pools of summer rain. NPS photo by Mark Lellouch.

Never approach wild animals. Photograph all wildlife from the safety of your vehicle. Use telephoto lenses and observe quietly. It is dangerous, and illegal, to feed wild animals in a national park. Violators will be fined. Wildlife can become dependent upon handouts and lose their ability to hunt and forage. Such animals lose their fear of humans. They can become aggressive and bite, kick, or gore. Many are struck by cars while searching for handouts. Help us keep wildlife wild. Never feed or approach wildlife.
