Polar Bear Week with Nigel Marven

Intrepid zoologist Nigel Marven explores the wildlife of the spectacular Canadian Arctic. From spring through to autumn, Nigel's expedition takes him from the icy wastes of the far north, across seemingly endless tundra to the vast boreal forest in the south.

The five-part series follows the fortunes of a range of animals as they attempt to triumph in the face of extreme conditions. From polar bear cubs fresh out of their birthing den, to an Arctic wolf's breathtaking attack on a herd of musk oxen, the series shows northern nature at its rawest. While polar bears are the main stars of the show, other animals featured include walrus, Arctic foxes, beluga whales, grey owls, harp seals and moose.
