Although three species of bears inhabit North America, only the black bear can be found in Pennsylvania. Population estimates in recent years have ranged from 8,000 to 10,000 bears. Black bears are very agile, can run up to 35 mph, climb trees and swim well. They may live up to 25 years in the wild, although few do. Black bears are intelligent and curious.
Studies show bears can see colors, recognize human forms, and notice even the slightest movement.
However, bears usually rely on their acute sense of smell and, to a lesser degree, hearing to locate food and warn them of danger. Despite their common name, black bears are not always black. They may be cinnamon-colored, blond or black. Often they have a white spot or on their chest. Black bears appear heavy and have short, powerful legs.
