Travelers on a National Geographic expedition to Antarctica
came across a leucistic chinstrap penguin. Unusual light coloring sets
this penguin apart from its black-and-white brethren. Often mistaken for
albinos, leucistic birds have a genetic mutation that restricts the
dissemination of pigment to feathers.
As you can see on the picture below, it is not completely albino, as there is sill a light pattern on it's back and feathers. It also doesn't have the red eyes. Albino animals lack all pigments in there body to be considered albino.
