A group of researchers set out to determine why two colonies of emperor penguins are sometimes found on sea ice and other times are atop large ice shelves. Analyzing impressively vivid satellite images and aerial surveys, they saw that, in years when sea ice formed according to a normal pattern, the birds set up breeding grounds on the ice. When the ice was late, as it was in 2011 and 2012, the colonies appeared atop ice shelves, which are large chunks of glacial ice that have broken off the mainland.

Exactly how they got up there is still a mystery, but scientists do know that the Antarctic Peninsula, where these colonies live, is one of the fastest-warming parts of the continent and has lost a significant amount of sea ice over the past 50 years. This behavior seems to indicate that the penguins are quickly adapting to their changing environment.

Fascinating adaptation. These birds don't fly, so they climb!

They don't fly YET ....

They're... Evolving...
