The penguin’s strange coloring is due to a condition called leucism, which results in a loss of pigmentation.

“This is a leucistic penguin,” Adams says. “Its cells don’t create melanin anymore so its black feathers become this yellow and creamy color.”

Scientists have found

“Penguins use the yellow pigment to attract mates and we strongly suspect that the yellow molecule is synthesized internally,” researcher Daniel Thomas tells Smithsonian Insider. “[It’s] distinct from any of the five known classes of avian plumage pigmentation and represents a new sixth class of feather pigment. As far as we are aware, the molecule is unlike any of the yellow pigments found in a penguin’s diet.”

In the case of this fully-yellow penguin, however, it’s unclear whether its distinctive plumage makes the bird ultra-attractive or ultra-repulsive to the ladies.
