Wildlife Photographer Captured Extremely Rare Yellow Penguin In Once-In-A-Lifetime Photos

Its similar to albinism but the animal keeps some of its pigments. 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 that the yellow pigment in penguin feathers is chemically distinct from all other molecules that are known to give color to feathers.
