A polar bear walks in the snow near the Hudson Bay waiting for the bay to freeze, 13 November 2007, outside Churchill, Mantioba, Canada. Polar bears return to Churchill, the polar bear capital of the world, to hunt for seals on the icepack every year at this time and remain on the icepack feeding on seals until the spring thaw.
