Dori is a female Black Bear (Ursus americanus) born in January 2010. She came to the Foundation because her previous facility burned down. When she was younger, Dori was featured on the Tonight Show with Jay Leno and Dave Salmoni. Dori came to the Foundation because she needed a home but she ended up playing an essential role in her companion’s recovery from a head injury he suffered as a cub. Dori will remain at the Foundation with her companion Winston as ambassadors to their species.

The black bear is North America’s smallest and most common species of bear. Black bears are omnivores, with their diets varying greatly depending on the season and location. The black bear is characterized by its broad head, narrow muzzle, and strong jaw. They have short, rounded claws and small, rounded ears. The black bear’s fur is soft a with dense underfur. Despite their name, black bears can show a great deal of color variation, including white, blond, cinnamon, dark chocolate brown, and jet black.

Black bears are incredibly intelligent and clever. They are capable of opening screw-top jars and manipulating door latches. They are also very strong and have been known to flip over flat-shaped rocks weighing up to 325 pounds with a single forelimb. Black bears are excellent climbers and are able to run at speeds up to 30 mph.

Black bears were once classified as not true hibernators; however, now they are considered highly efficient hibernators because it was discovered that they possess the ability to change their metabolism and remain dormant for months. Black bears typically hibernate in cold weather conditions and when food is scarce. Depending on the climate, black bears will enter their dens in October and November and typically hibernate for three to eight months, but they remain somewhat alert and active during this time.

The black bear has a widespread distribution and a large global population estimated to be twice that of all other bear species combined. They typically live in largely forested areas, but will leave in search of food. Although American black bears are quite capable of killing a human, they typically avoid confrontation with humans as much as possible. The majority of black bear attacks tend to be motivated by hunger. The best way to prevent conflict with a black bear is to avoid it all together and properly manage any food sources that may attract a bear.
