The Adelie Penguin is one of the most easily identifiable Penguin species with a blue-black back and completely white chest and belly. The head and beak of the Adelie Penguin are both black, with a distinctive white ring around each eye. The strong, pink feet of the Adelie Penguin are tough and bumpy with nails that not only aid the Adelie Penguin in climbing the rocky cliffs to reach its nesting grounds, but also help to push them along when they are sliding (rowing) along the ice.
