This video was shot over one week during several visits to the area near Churchill. Manitoba, Canada where polar bears congregate waiting for Hudson Bay to freeze. Once the Bay freezes the bears will move onto the ice to hunt ring seals. These bears have been on land during the summer months and move to the shore of Hudson Bay late October for the beginning of freeze up. One of the behaviours shown here is wrestling which the male bears do while waiting for Hudson Bay ice to form.
