This week's programme in the series of films from all over the world about our astonishing planet and the creatures that live on it features a tiny island in the sub-Antarctic, the home of the world's largest sea-birds - wandering albatrosses. They share Bird Island with vast numbers of fur, leopard, and elephant seals; with penguins and a wide variety of other birds.
For 18 months three scientists worked through storm, sunshine, and blizzard, studying the wandering albatrosses and filming this unique record of the wildlife of Bird Island.
