Who is it?

The Brown bear (or Ursus arctos) is a species which is scattered over various habitats, although it generally prefers to live in dense forests, alpine tundras and river valleys. . Brown bears are the largest existing carnivores: the Kodiak bears of Alaska, for example, is capable of reaching 600 kg, and only the polar bear is larger than it.

The wide geographic distribution of this bear, covering three continents, ,is due to the fact that this is an omnivorous animal which is capable of exploiting all natural resources. It is an intelligent animal which makes use of any experience it has had.

It hibernates in hideaways or caves which are difficult to reach and has an especially well-developed sense of smell and hearing. Their cubs well about 400 g at birth, in the middle of winter. The mother is responsible for caring for them, showing a strong maternal instinct which includes aggressive behaviour (if their cubs are disturbed). Play is an important part of the life of bears, in both juveniles and among adults. ..

The brown bear feeds on plant and animal matter: : bulbs, fungi, insects, mammals, fish and even carrion.
