Frozen Planet

Winter is the greatest test for life in the polar regions, as temperatures plummet to 70 below and winds reach 200kph. Only a few remarkable survivors gamble on remaining in these extreme conditions. In the Arctic, a female polar bear treks into the mountains to give birth. Out on the frozen ocean, the entire population of the world's spectacled eider ducks braves the winter in a giant ice hole.
