The curators have constructed “dens” of various kinds in the Wild Enclosures, mostly out of culverts. Usually, the cubs and yearlings ignore these structures unless they are playing on them in the summer. But our resident (soon to be released) yearling, Bud, has adopted one of the culvert dens. This is likely because it is getting closer and closer to hibernation time, and Bud knows it!
Bud is a healthy and chonky yearling. He will definitely be ready to resume his wild life soon.
