The Adelie Penguin is the smallest and most widely distributed species of Penguin in the Southern Ocean and is one of only two species of Penguin found on the Antarctic mainland (the other being the much larger Emperor Penguin). The AdeliePenguin was named in 1840 by French explorer Jules Dumont d'Urville who named the Penguin for his wife, Adelie. Adelie Penguins have adapted well to life in the Antarctic as these migratory Birds winter in the northern pack-ice before returning south to the Antarctic coast for the warmer summer months.
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. Adelie Penguins also use their webbed feet along with their small flippers to propel them along when swimming in the cold waters.
