The adorable video of the siblings was posted to the AWCC’s Facebook and has amassed over 92,000 views. The two brown bears, 17-year-old brother and sister Joe Boxer and Patron have been living at the conservation center since 2004.

According to the AWCC website, JB and Patron arrived at the center after their mother was killed by a man when she entered his backyard and killed a moose calf. In this case, the man was afraid the mother bear would attack his dog, and it is actually legal to kill a bear in self defense or in defense of property. But he didn’t realize she brought her cubs with her.

“Once he saw the two cubs, he called the area wildlife biologist to notify him of the situation,” the AWCC website read. “The biologist, who happened to be a former gymnast, daringly climbed to the top of the skinny tree the cubs were hiding in.”

The biologist was able to grab the male cub, JB, and place him in a fishing net nearby, but Patron was much bigger and more aggressive. After sedating the cub, the biologist monitored the sibling brown bears and delivered them to their new home at the AWCC where they’ve been thriving since.

The cubs have now grown into large bears, but the AWCC said they still love to roughhouse together in their sanctuary. But in the video that’s making everyone smile, JB and Patron approach each other in a lush green setting before synchronously rolling over onto their sides for a deep sleep.

It only takes them a moment of wiggling before knocking out in what people are joking was their way of practicing for the upcoming hibernation. These brown bears start their five- to six-month hibernation beginning in October. During this time, the bear’s heart rate and body temperature drop but the bears can always be easily awakened if need be.

The video was filmed by AWCC’s Social Media and Administrative Manager Alex Roberto. She filmed the siblings from the conservation center’s aerial boardwalk which overlooks the sanctuary.

The AWCC is a nonprofit organization based out of Portage, Alaska which provides hurt and abandoned animals with over 200 acres of sanctuary.
