Seldom Seen None of these species is rare, but the nocturnal or secretive habits of many of them make casual sightings rather infrequent. Opossums, raccoons, and skunks are more often heard foraging in campgrounds at night than they are seen. All of these animals subsist on a wide variety of foods and can be found throughout the park. Bobcats, red foxes and gray foxes, weasels, and mink are all predators. At dusk bobcats and foxes are sometimes seen along roads.
Bobcats have short tails.
Red foxes and gray foxes are omnivorous. Both species are common in the park, but gray foxes are more numerous. Weasels and mink are about squirrel-size predators, generally brownish in color, and occur throughout the park. Members of the mouse family are numerous. These animals, the majority of which live in fields, range in size from the tiny eastern harvest mouse to the muskrat.
