Brown bear

Ursus arctos

Description:
Brown bears weigh between 300 and 780 kilograms. In the summer, they gain up to 180 kilograms of fat, which helps them to survive through the winter when they become very lethargic. Adult male bears and female bears with cubs are very aggressive. Sounds expressing anger include growling, roaring and barking. Mother bears bleat or hum to their cubs. At birth, the cubs are blind, toothless and hairless, and weigh less than 450 grams. They feed on their mother’s milk until spring or early summer, depending on climate conditions. Cubs remain with their mother for two to four years, during which time they learn to survive by themselves.

Habitat:
The brown bear can be found in many places in Europe, Asia and North America. There are about 200,000 brown bears in the world. The largest populations are in Russia, the United States and Canada. In Europe, brown bears live in the Pyrenees, the Balkans and Northern Europe.

Habits:
Brown bears like to spend the winter months in a protected place, such as a cave, crevice or hollow log. They are not full hibernators and can be woken easily. They are omnivores and feed on a variety of plants, including berries, roots and fungi, as well as fish, insects and small mammals. Brown bears occasionally kill larger mammals, such as deer, sheep or mountain goats.
