The brown bear lives in the forests and mountains of northern North America, Europe, and Asia.
It is the most widely distributed bear in the world. In fall a brown bear may eat as much as 90 pounds (40 kilograms) of food each day, and it may weigh twice as much before
hibernation as it will in spring.
Brown bears dig dens for winter hibernation, often holing up in a suitable hillside. Females, or she-bears, den while pregnant and give birth
during this winter rest, usually to a pair of cubs. Brown bear cubs nurse on their mother's milk until spring and stay with her for some two and a half years—so females only
reproduce once every three years.
