Have You Ever Seen the Mass Molting of a Colony of Penguins!?Matthew M. Sullivan
When the Antarctic temperature drops at the start of winter, thousands of penguins must shed their summer plumage for a thicker, winterized coat. As their feathers float away in the winter wind, Antarctic penguins must conserve energy — they are unable to dive and feed until they have completely molted and regrown their feathers.
In this video, Sir David Attenborough takes us into a whirlwind of penguin feathers as the Antarctic winter descends upon a penguin colony at Deception Island — watch the video!
