While we are preparing for the holidays, bears in the center “Synevyr” are going into hibernation

Recently, employees of the Rehabilitation center for brown bears in the Park "Synevyr" were worrying that the bears would not go into hibernation. But now, the preparation for winter sleep is going according to seasonal changes, the zaholovok informs. With the arrival of winter, the temperature below 0º C has remained for more than 30 days.

The bears are getting ready for winter sleep, and some are already hibernating. 

There are 24 artificial dens in the center, but most bears build their dens themselves – under the roots or trunks of trees. During the winter sleep, bears do not eat anything and live on subcutaneous fat that has accumulated during summer and autumn. The duration of sleep is 75-140 days, from snowfall to March-April, depending on weather conditions and nutritional status. Therefore, the center developed appropriate rations that meet the physiological needs of the brown bear, depending on the season.

During the winter sleep, bears do not go completely numb. Their body temperature decreases by 4-5ºC, pulse – by 75%, and oxygen consumption – by 50%. During the sleep they move, roll, they can hear different sounds and, in an emergency, leave the den.
