Antarctica 2010 - 2011

Adélie Penguin molting. A penguin's feathers are very important for keeping them warm and dry while they are in the cold ocean water. Over time their feathers may wear and break (imagine wearing a sweater everyday for a year, it is bound to get some holes in it, and look a little worse for wear). In order to replace these feathers, penguins go through what is called a molt, where their old feathers are pushed out and replaced by new ones.
