Black bears are a medium sized bear found in North America. They are excellent climbers. Their claws give them good grip and the branches provide safety for younger bears. Their average lifespan in the wild is 20 years. Adults range from 5-6 feet in length and weigh 200-600 pounds. They have a small head with small, rounded ears. Their claws are non retractile unlike dogs and cats.
Black bears are not territorial and the home ranges of both males and females overlap. Home ranges are generally larger where there is less food and smaller when there is more. Black bears do become dormant in the winter. They spend their winters in dens.
