We know that bear cubs feel very comfortable in trees.  Cubs in the wild, who are sent up a tree by their mother, will stay there until she calls them down – sometimes for hours at a time.  They will pass the time in the tree by resting, snoozing, and playing.  Our ABR cubs climb the trees many times a day, and engage in the same activities mentioned above.  Tree-climbing is a skill they will need after their release into the wild, and it helps them to develop and strengthen their muscles and practice their balance. We think you will enjoy this video.  It shows two of our cubs playing with each other while performing some rather perilous (to our eyes, at least) acrobatic moves.
