Our Black Bear
Name(s)
Randolph
Origin
Found orphaned at approximately 12 weeks old in Randolph County, North Carolina. When taken in by rehabilitators he was dehydrated, underweight, and covered in ticks.
Why He's Here
As an orphan, Randolph missed essential survival and socialization lessons from his mother. He was deemed non-releasable after becoming habituated to humans due to the level of care he required. He arrived at the Science Center at eight months old in October 2022.
How You Can Help
To keep wild bears wild, never feed or approach bears, secure your trash and recycling at home, and remove bird feeders when bears are active.
Black Bear Fun Facts
- American black bears are powerful swimmers, traveling at about three to five miles per hour. With short, sturdy claws, American black bears are also excellent tree-climbers. If you are walking a forest with beech trees you may see the claw marks they left behind in the bark as they climbed the trees for beech nuts.
- Size varies in American black bears—male bears may be 20 to 60 percent larger than the females.
- An American black bear’s sense of smell is very acute, helping them find food and avoid danger.
Black Bear FAQs
Are American black bears always black?
American black bears in the northeast are generally black, often with a white patch on their chest. In western parts of their range they can also be various shades of brown or in southeastern Alaska and coastal British Columbia even blond or bluish gray.
Where are American black bears found?
American black bears live in most of Canada as well as Alaska and many of the other forested continental states. Bears often inhabit inaccessible mixed stands of conifers and hardwoods with thick under story and swampy areas. Home range for bears varies from about 10 square miles for females and up to120 square miles for males.
What do American black bears eat?
Although included in the order Carnivora, American black bears have a decidedly omnivorous diet. Insects, such as beetles, colonial ants and bees, along with nuts, berries and vegetation form the bulk of their diet. They will also feed on carrion, small mammals and the young of deer and moose. You can help keep bears wild and safe by not feeding them. Store your garbage properly and bring bird feeders in at night from spring to fall when bears are active.
How is their winter sleep different from hibernation?
American black bears feed heavily in summer and fall to build up a fat supply and do not eat during the winter. However their body temperature does not lower significantly during their dormancy like true hibernators. Dens are often made in roots of fallen trees, brush piles or a hollow tree. On warm winter days, American black bears may awaken and walk around outside the den. In late January or February, bear cubs are born, each weighing about eight ounces.
Should we be afraid of bears?
American black bears are generally secretive and slip away before we are aware of them. Even American black bear females with cubs are unlikely to attack people – they send their cubs up a tree and either retreat or bluff. People should take precautions by not intentionally approaching bears or encouraging them with food.
