Polar bears are normally solitary, but each year, usually in November, they congregate in this area and wait for the water in the bay to freeze. They have to wait until the ice is thick enough to support their weight so they can hunt for seals. Play-fighting during this period is normal behavior. It’s practice for more serious standoffs during mating season.
