The Hunt: In the Grip of the Seasons

Cameras follow predators living in the Arctic, who face a particularly challenging search for food, as the environment around them constantly changes with the seasons, from a continent of ice in perpetual darkness to a scattering of islands in constant sunshine. A polar bear climbs to reach a birds' nest, while another makes holes in the ice to catch seals. Plus, a look at how Arctic foxes have adapted to catch auks in mid-flight and the hunting strategies of Arctic wolves. Narrated by David Attenborough
