Polar Bear Habits | Wild: Polar Bear Diary | BBC Earth

Scientists are still learning new polar bear habits and are constantly surprised by their coping skills in a hostile habitat. Malcolm Ramsey, a scientist who has been researching these bears for the past 20 years, is still amazed by their internal GPS systems and their ability to return home in an ever changing landscape. Great clip from BBC's natural history documentary, Wild: Polar Bear Diary.
