Remote South Georgia Island, about 1,200 miles east of South America’s southern tip, is a seasonal home for only a few dozen humans—but many thousands of seals, penguins, and other creatures.

On a recent National Geographic expedition to the island, photographer Jeff Mauritzen happened upon some animals that were birds of a different feather: A king penguin and fur seals with separate, yet rare, genetic mutations that make them all appear pale.

The striking penguin was spotted on a rainy morning, and as luck would have it, the weather cleared for about ten minutes, just enough time to get some photographs, Mauritzen says.

Like other birds, king penguins can have several mutations that affect how their bodies make pigments.
