For the animals in the polar regions, autumn means dramatic battles and epic journeys. Time is running out - the Arctic Ocean is freezing over and the sea ice is advancing at 2.5 miles per day around Antarctica. Polar bears gather in large numbers on the Arctic coast as they wait for the return of the ice. Soon, tempers fray and violent sparring contests break out. Meanwhile 2,000 beluga whales head for one special estuary, a gigantic 'whale spa' where they will thrash their snow-white bodies against the gravel and exfoliate. Inland, the tundra undergoes a dramatic transformation from green to fiery red. Here, musk ox males slam head-first into each other with the force of a 30mph car crash as they struggle to defend their harems. Frisky young caribou males play a game of 'grandma's footsteps' as they try to steal the boss's female. Down in Antarctica, Adelie penguin chicks huddle together in creches. When a parent returns from fishing, it leads its twins on a comical steeplechase - sadly there's only enough for one, so the winner gets the meal. Two months later and the chicks are fully feathered apart from downy Mohican hairdos - they're ready to take their first swim - reluctantly though, as it seems penguins are not born with a love of water! And with good reason - a leopard seal explodes from the sea and pulls one from an ice floe, a hunting manoeuvre that has never been filmed before. As winter approaches and everyone has left, the giant emperor penguin arrives and makes an epic trek inland to breed. The mothers soon return to the sea leaving the fathers to hold the eggs and endure the coldest winter on earth.

The Auckland Islands are an isolated archipelago of islands far south of New Zealand. They might seem bleak, but they are a surprising sanctuary for wildlife. In summer, hordes of giant sea lions descend upon a desolate beach, and testosterone-driven males begin bloody battles for mating rights. When the pregnant females return to give birth on the beach, chaos ensues. The pups are always in danger of being squashed by overly eager males. Some of the rarest penguins on the planet, the yellow-eyed penguins, are also breeding here and must constantly evade the huge brawling male sea lions. Southern royal albatross, giant petrels and skuas are other species that go to extremes to ensure their offspring’s survival. The drama of summer in the sub-Antarctic islands peaks as the sea lion pups dare to take their very first ocean swims.
