The once-rare sight of polar bears migrating in Canada can now be seen by just about anyone, thanks to a live webcam.
Every fall, hundreds of polar bears travel through the small town of Churchill, Manitoba, in central Canada, on their way to Hudson Bay, where they hunt for seals on the ice. For years, the journey has been seen for the most part by scientists. But now, thanks to a grant of $50,000, a vehicle called the Tundra Buggy roams the area with a camera whose live pictures anyone can see at www.explore.org. (Always ask a parent before going online.)
