See this rare white Gentoo penguin discovered in Antarctica

This week, scientists are intrigued by the discovery of a nearly white penguin that was discovered in Chilean Antarctica.

The penguin, which is a female, is part of a colony of Gentoo penguins — who usually have black heads, white spots around their eyes, and bright red or orange bills. But this one’s head is a very light gray color, its bill is a pale pink, and most of its body is white.

She was discovered by researchers who study the Gentoos at the González Videla Antarctic base.

In this TikTok video for the BBC, Chilean Army cook and photographer Hugo Alejandro Harros Guerra explained that there are 14 people who live in the middle of this colony of hundreds of penguins. “Every day Antarctica and this beautiful place surprise us with something different,” he says. The video, shot by Guerra and used by the BBC on their TikTok account, gives you an idea of what the other penguins in this colony look like, and how this one stands out:

The penguin’s unusual coloring is due to a genetic mutation called leucism. It’s similar to albinism, a condition that impacts melanin production. But with leucism, the effects are only partial, so the animal has some coloring. A similar genetic mutation has popped up in alligators, whales, giraffes, bison and other species.

While Gentoos are among the largest penguin species physically, they are among the least numerous, with only about 300,000 breeding pairs.
