A polar bear looks out over a barrier island on the Arctic coast of Alaska. These islands are important habitat for the polar bear because the creatures use sea ice as a hunting platform. Take a look at the highlight reels of two webcams located in Churchill, Manitoba, where polar bears wait for the Hudson Bay to freeze so they can reach their seal-hunting grounds.
