Mammals include black bear, coyote, striped skunk, spotted skunk, raccoon, beaver, river otter, opossum, woodchuck, bobcat, two species of foxes, white-tailed deer, and eastern cottontail rabbit. Though unsubstantiated, there have been some reported sightings of cougar in remote areas of the park. Over 200 species of birds make their home in the park for at least part of the year. About thirty live in the park year round, including the barred owl, Carolina chickadee, red-tailed hawk, and wild turkey. The peregrine falcon was reintroduced into the park in the mid-1990s and by the end of the 20th century there were numerous nesting pairs in the park. Thirty-two species of fish have been documented in the park, including brook trout, longnose and eastern blacknose dace, and the bluehead chub.
