Climate change has penguins on the march

In the 1970s, biologists noticed that the Pointe Géologie colony -- the group made famous by the "March of the Penguins" documentary -- had diminished in size. Scientists assumed that rising ocean temperatures and melting ice had killed off many of the penguins. But new evidence suggests members of the colony branched off and joined other groups.

In recent years, scientists have been better able to track the location of penguin colonies in Antarctica. Using satellite imagery scientists can quickly and easily pick out the stains of the species' dark fecal droppings against the pristine snow and ice.
