Watch Natural World Season 34 Episode 7 Online

Welcome to the Penguin Post Office, a little bit of Britain in the heart of Antarctica. Inside, the post office has everything you'd expect; a postbox, stamps, postcards and some dedicated staff. Outside, things are a little bit different. Neighbouring the post office are 3,000 gentoo penguins. They are there to raise a family but their lives are far from picture postcard as adultery and robbery are rife. The post office and its penguins attract thousands of visitors. Whilst they come and go, the penguins must keep up with daily chores to ensure their chicks make it to sea before the Antarctic winter starts to bite.
