Brown bear

Mammals

The brown bear, Ursus arctos, is a large bear native to Eurasia and North America and, among land carnivorans, rivalled in size only by its closest relative the polar bear. Adults generally weigh 80 to 600 kilograms, with males at least 30 percent larger than females, and the fur runs from cream through reddish to dark brown. Large hump muscles, unique among bears, and broad paws help it dig. It is omnivorous and takes about 90 percent of its diet from plants, though it also hunts animals from insects and rodents up to moose, and in places such as the Kamchatka peninsula and coastal Alaska it feeds mostly on spawning salmon. It lives mainly in forested habitats from sea level up to 5,000 metres and averages about 25 years in the wild. The IUCN lists it as least concern, although several southern populations are highly endangered and others, such as the Atlas bear, were hunted to extinction.
