The 14-year-old brown bear Diana has been hibernating for ten days now. She is one of the nine representatives of her species, raised with a lot of love and care in the Stara Zagora Zoo. One of the oldest bears living in a Bulgarian zoo actually lives here - 26-year-old Bella. With the exception of Diana, however, all the other bears in the park are awake.

"Bears that were not born in nature skip hibernation. The conditions that have been created in Diana's habitat come as close as possible to the brown bear's natural habitat, which helps her falling asleep in the winter months," says Dr. Ivelina Ilieva, head of the zoo.

The zoo also published a video of Diana preparing for her winter nap.
