What months do black bears hibernate in Pennsylvania?

Pennsylvania black bears typically enter a state of dormancy known as winter sleep or torpor during the months of December through March. During this period, their metabolic rate slows down, and they conserve energy by entering a deep sleep-like state. However, it's important to note that black bears do not truly hibernate like other species, such as woodchucks or groundhogs. They can periodically wake up during warm spells and may even leave their dens to search for food if necessary.
