The grizzly bear (Ursus arctos horribilis), also known as the silvertip bear, the grizzly, or the North American brown bear, is a subspecies of brown bear (Ursus arctos) that generally lives in the uplands of western North America. This subspecies is thought to descend from Ussuri brown bears which crossed to Alaska from eastern Russia 100,000 years ago, though they did not move south until 13,000 years ago. Except for cubs and females, grizzlies are normally solitary.
The grizzly bear, less commonly called the silvertip bear, is any North American morphological form or subspecies of brown bear, including the mainland grizzly, Kodiak bear, peninsular grizzly,and the recently extinct California grizzly, and Mexican grizzly bear.
