Brown Bear Lifestyle
The predator shows its main activity in the morning and evening twilight. At the same time, the animal is oriented in space due to its fine hearing and sense of smell.

The diet of brown bears
It is believed that brown bears, although they are predators, they are omnivores. At the same time, the basis of the diet is represented by food objects of plant origin. Therefore, they eat everything they can find on their territory: berries, nuts, acorns, roots, tubers, as well as the stems of various plants. In addition, bears eat insects, in the form of ants, worms, lizards, frogs, field and forest rodents.

Brown bear hibernation
Brown bears, though, fall into hibernation: but not so actively, if you compare this process that occurs with other mammals. The hibernation period of the brown bear is characterized by the fact that its body temperature, respiratory rate and heartbeat are almost at the same level as before hibernation. In the first days, he practically does not sleep, but only dozes. At the onset of severe cold weather, predators fall into hibernation, and this period can last no more than a month. During this period, the animal feeds on subcutaneous fat, which the bear managed to accumulate before the onset of cold weather, although this is not always possible.
