Bears in Siberia are wandering around "half-asleep" following abnormally high temperatures this fall, according to the Department for the Protection of Wildlife of the Amur Region.

The bears are ready to hibernate, having accumulated the fat reserves needed to sleep through the winter, but warm temperatures in November have kept them up past their bedtime, the government department said in a translated Telegram post on Nov. 21.
