This huge colony on Macquarie Island in the Australian Sub-Antarctic is extraordinary and goes for as far as the eye can see. It is a seething mass of penguin society. Parents sit on eggs or hide their young under a big flap of skin between their legs. Antarctic skua fly in and try to distract the parents and steal the egg, or even a chick. One skua flew off with a chick just as I was photographing it! The noise of thousands of penguin families is deafening. While the parents stick together in a tight huddle on the hill, the other penguins huddle together on the beach.
