With the help of some surprising creatures from around the world, this series sets out to discover how animals take to the air, defying the force all airborne animals must conquer, gravity. Part 2: Masters of the Sky This episode looks at powered flight, revealing why peregrine falcons can top 200 miles an hour, how a hummingbird is a slave to its own rather manic lifestyle and that the albatross's secret to flying for free is its nose. Heavyweight beetles break the rules to find love, a devious sparrow-hawk uses agility to execute a lightning-fast raid on his prey and half a million mother bats dominate the sky above, and below, the ground with a dazzling display of aerial prowess.

The annual Serengeti wildebeest migration is a journey so fraught with peril, it's a wonder they set off at all. For wildlife expert Jean du Plessis, it's a unique chance to see how a new generation of calves, born just months ago, will fare among the predatorial lions and crocodiles that await them.

There is no greater test for life than winter, as temperatures plummet to 70 below and winds reach 200kph. Darkness and ice extend across the polar regions and only a few remarkable survivors gamble on remaining. We join a female polar bear trekking into the Arctic mountains to give birth as the first blizzards arrive. Out on the frozen ocean, the entire world's population of spectacled eider ducks brave the winter in a giant ice hole kept open by ferocious currents. Arctic forests transform into a wonderland of frost and snow - the scene of a desperate and bloody battle between wolf and bison, but also where a remarkable alliance between raven and wolverine is made. Beneath the snow lies a magical world of winter survivors. Here tiny voles dodge the clutches of the great grey owl, but cannot escape the ultimate under-show predator - the least weasel. Midwinter and a male polar bear wanders alone across the dark, empty icescape. Below the snow, polar bear cubs begin life in an icy den while fantastical auroras light the night skies above. In Antarctica, we join male emperor penguins in their darkest hour, battling to protect precious eggs from fierce polar storms. Weddell seals escape to a hidden world of jewel-coloured corals and alien-looking creatures but frozen devastation follows as sinister ice stalactites reach down with deadly effect.
