Latest Research: Breeding of Color-Aberrant Adélie Penguins at Cape Crozier, Antarctica.  Cape Crozier, Ross Island, Antarctica, is one of the largest Adélie penguin colonies in the world. Because of the unusually large size of the colony, it is one of the best places in the world to study extremely rare events, like color abnormalities. We compared the fraction of abnormally colored individuals breeding to a sample of normally colored individuals and found that likelihood of breeding and successfully raising chicks was similar for both groups.
