The cubs and yearlings at ABR have many choices of activities to fill their days. One of the most important is eating, of course, but there are others as well. They can stay active at night, as well as during the day.
Yearling bears are loners, having been dispersed from the family unit during the time of “family breakup.” As loners, Mulberry and Augustus do not socialize with each other the way the cubs do. They maintain good social distancing, and take turns using the various amenities in Wild Enclosure #4, which they share.
