Sir David Attenborough presents the emperor penguin from the Antarctic Peninsula. With temperatures down to minus 50 degrees Celsius, midwinter blizzards scouring one of the most inhospitable places on the planet, this is not an obvious location for raising young. Tightly-packed colonies of hundreds or sometimes thousands of birds huddle together, to conserve heat. Females travel up to 100km from the colony in search of food, using a technique called tobogganing which is far more efficient than walking on their short legs.
