In addition to feral horses, the Pryor Mountains Wild Horse Refuge is a good place to see other wildlife and plant species. Among the species found there are Rocky Mountain bighorn sheep, black bears, blue grouse, cougars, elk, gray wolves, mule deer, ring-necked pheasant, and sage grouse. The Pryor Mountains are also home to the most diverse bat populations in Montana, with 10 species identified (and potentially other species also present).
