Brown bear

Scientific name :
Ursus arctos
Class :
Order :
Family :

The brown bear is a highly skilful animal whose ponderous gait disguises remarkable agility (maximum speed of 50 km/h). Its dense fur covers a thick layer of fat. This species can be identified by the distinctive mound of fat and muscle on its shoulders. Males usually come into contact with females only during the mating season. Juveniles live with their mother for around two years, after which time the males leave, although the females may stay on.


Geographic distribution of the brown bear

Brown bears are found in Europe, North America and North Asia.

From mid-December to mid-April, brown bears go into hibernation: they withdraw into a lair and stop feeding, using the fat reserves they accumulated during the summer. Females produce their litter during this period.



Although its teeth are those of a carnivore, the brown bear is omnivorous and 80% of its food comes from vegetation. It requires a massive calorie intake.

Unlike other hibernating animals, such as the marmot, some animals that overwinter, including bears, are able to wake up several times during the cold season to get some fresh air, feed or simply defecate.
