brown bear

any of several medium-sized to large bears of the species Ursus arctos, inhabiting North America and Eurasia in dwindling populations, characterized by an upturned muzzle and a hump high on the back and ranging from light tan to near black; formerly considered three distinct species and often still referred to as such: U. horribilis, the grizzly bear; U. middendorffi, the Kodiac bear; and U. arctos, comprising European and Asian brown bears.

Shaggy-haired, characteristically brown species (Ursus arctos) of bear with numerous races native to Eurasia and to northwestern North America.

North American brown bears are usually called grizzly bears. Eurasian brown bears are generally solitary animals, able to run and swim well, and usually 48–84 in. (120–210 cm) long and 300–550 lbs (135–250 kg). They feed on mammals, fish, vegetable materials, and honey. The exceptionally large Siberian brown bear is similar in size to the grizzly.

 shaggy-haired bear (family Ursidae) native to Europe, Asia, and northwestern North America. More than 80 forms of brown bear have been described; they are treated as several subspecies of Ursus arctos. North American brown bears are traditionally called grizzlies (see grizzly bear).

      Eurasian brown bears are generally solitary animals that are able to run and swim well. They are usually 120–210 cm (48–84 inches) long and weigh 135–250 kg (300–550 pounds); the exceptionally large Siberian brown bear (Ursus arctos beringianus), weighing as much as 360 kg (800 pounds), approximates the size of the North American grizzly. Eurasian brown bears feed on mammals, fish, and plant material. Coat colour is highly variable, ranging from grayish white through bluish and brownish shades to almost black. Eurasian brown bears are commonly seen in zoos; formerly they were often trained to move rhythmically to music—the so-called dancing bears of European carnivals and festivals. They originally roamed most of Europe and Asia, and, though perhaps 100,000 remain in northern Eurasia, the southern range has been significantly reduced.

      Brown bears are omnivorous and feed on berries, plant roots and shoots, small mammals, fish, calves of many hoofed animals, and carrion. They often cache food in shallow holes, and they dig readily and strongly in search of rodents. Except in some southern areas, bears retire to dens in winter and therefore accumulate large amounts of fat during late summer and autumn. Cubs, usually twins, are born in winter after about 6–8 months of gestation. At birth a cub weighs less than a kilogram.
