American black bears are basically timid animals and easily frightened. Cubs, being so small, are even more easily frightened than older bears. Today we have a video of the cubs in Wild Enclosure #2, reacting to what they perceive as danger. In this video we see the cubs having a normal, easy-going morning until something startled them. It was probably the sounds of curators working near their enclosure, but whatever it was, it sent them into their escape or avoidance-of-danger mode, which meant, of course, that they hurried to climb the trees. Climbing trees is the escape route of choice for bears, and these cubs do it well. Watch how quickly they go up or down a tree – it’s amazing!
