BBC Natural World - Ghost Bear Family (2015)

In the vast Canadian wilderness, there lives a very special bear family. Just out of hibernation, two black cubs have a pure white mother. She's not a polar bear or albino - locally she's known as a ghost bear. This far north, winter is never far away, and this unusual family must work hard to find enough food to see them through. They will also need to avoid other large predators, but being so different could bring them unwelcome attention.
