The first of three programmes
A global celebration of birds
Narrator Magnus Magnusson
There are 10,000 kinds of birds. Without their songs, splashes of colour and flamboyant displays, the world would be an impoverished place.
Birds even survive in the polar regions where the climate is extreme, the bright summers brief. Emperor penguins of the Antarctic start to breed during the freezing winter, starving for four months. In spring, beautiful snow petrels nest in ice cliffs in the remote interior. Wilson's petrels dance over the sea, skuas steal, sheathbills scavenge, adelie penguins run the gauntlet of leopard seals.
With arctic fox, snowy owl and gyrfalcon ever-present threats, Arctic birds rely on camouflage, rocky crevices or high, inaccessible cliffs to hide their nests and young. Ivory gulls venture further north than any other bird, ptarmigan alter their plumage from summer brown to white, remaining through the winter, while others flee. The Arctic tern flies 18,000km south to enjoy a second summer in the Antarctic.
