This rare leucistic Chinstrap penguin spotted in Antarctica on Monday lacks the standard black-and-white coloring of most penguins.

Yes, we know, we already posted today's photo of the day. But we liked this shot so much that we wanted to share it with you.
David Stephens, a naturalist aboard Lindblad Expeditions' National Geographic Explorer ship, photographed this rare white Chinstrap penguin on Monday on Antarctica's Aitcho Islands.
"At the water’s edge stood a leucistic Chinstrap," Stephens wrote in the ship's daily expedition report. "This bird was whitish, but not quite an albino. Instead, it had pigmented eyes and a washed-out version of a Chinstrap’s normal pattern. Many wondered about this unusual bird’s chances of success. While odd coloration may make fishing a bit more difficult, leucistic birds are regularly found breeding normally."
A leucistic bird has reduced pigmention, unlike a bird with albinism, which is a lack of skin pigment. The standard black-and-white coloring found on penguins serves as camouflage that aids the bird in fishing, so it's unusual to find a penguin without it.
“It is a fairly rare phenomenon,” said Dyan deNapoli, a penguin expert and author of "The Great Penguin Rescue," who added that the rate of leucism in Chinstrap penguins is about 1 in 146,000. "When I was in Antarctica, I never saw one, and I saw a lot of penguins." Source
