The brown bear, Ursus arctos, has the widest range of any bear species. It lives in northern North American, Europe and Asia. Its subspecies include the grizzly bear, the Eurasian brown bear and the largest of all, the Kodiak bear. Brown bears range in color from blonde to nearly black.
Although they are classed as carnivores, brown bears get much of their food from nuts, berries, roots, leaves and fruits. They eat prey animals of all sizes, from insect grubs and small rodents to caribou and moose. They also eat the remnants of other predators' kills. During salmon runs in North American rivers, brown bears catch and eat many of the fish. Bears can eat up to 90 pounds of food daily.
Brown bears weigh only 14 to 18 ounces at birth, but they grow into some of the planet's largest carnivores. Brown bears range in size from 176 pounds for a small female to 1,213 pounds for a big male. The heaviest recorded brown bear was a Kodiak bear that weighed 2,500 pounds. Brown bears can grow up to 9.2 feet long and 5 feet tall at the shoulder. Males are much larger than females, and the Eurasian subspecies is smaller than the grizzly or the Kodiak.
