No, no, YOU go first

June 14, 2009

One Adelie penguin looks doubtfully at the water while another cries out for it to get a move on. No penguin wants to be the first one in, so they egg each other on with a barking call heard nowhere else but on ice. They’re not afraid of the cold. The water holds something far worse than a case of the shivers — leopard seals, which patrol the coastline of Antarctica, waiting for an Adélie with poor timing to dive in.
