rare white penguin

An adult, unpigmented Adelie penguin was photographed near Granholm Hut on Sunday.
Penguins lacking pigmentation are referred to as "leucistic" and do not usually survive until adulthood because they attract predators and don't breed.
Australian Antarctic Division biologist, Rhonda Pike, says only one penguin with the genetic defect has been detected over a number of breeding seasons in a population of 4,000 Adelies.
