Pronghorn

Often seen in brushy areas, forests and open grasslands, mule deer eat mostly grasses and shrubs. Their large ears, resembling mule’s ears, are helpful in detecting approaching predators, of which they have a few: wolves, coyotes, cougars and bears.

Bison have inhabited the Grand Teton and Yellowstone region since prehistoric times. They live in the area year-round, favoring grasslands in the summer, where they eat mostly grass and sedges.

One of the most unique and charismatic animals in the region, moose are the largest members of the deer family. During summer months, they’re most often seen in marshy or riparian areas browsing on aquatic plants and willows.
