Grizzly Bears at play?

Our grizzly bear viewing area in British Columbia’s Knight Inlet is home to more than fifty bears. The abundance of salmon in our tours’ area reduces the need for bears to fight for the best fishing place. In fact the grizzly bears, big or small, seem to coexist with out much conflict. So it is hard to tell if this is serious or just playing. I was not present when the photo was taken.
