Polar bears are now gathering on the Hudson Bay's southwestern shore to wait for the water to freeze so they can trek the ice in search of food. Live webcams set up in and around Canada's Wapusk National Park allow us to witness the migration and a new feature lets you take webcam snapshots of the bears playing or lazing on the tundra, then download or share those pictures through email and social media. Your kids are going to LOVE this. You are too! MASH RIGHT HERE to watch. Be sure to notice the temperature and wind speed at the top!
