"They are extraordinarily like children, these little people of the Antarctic world, either like children, or like old men, full of their own importance and late for dinner, in their black tail-coats and white shirt-fronts - and rather portly withal."
The Adelie Penguin (Pygoscelis adeliae) is the most common of all penguins in Antarctica. They nest near the shore in groups of 6 to 100s called rookeries. There were tens of thousands of them in the vicinity of Dumont d'Urville, even under the buildings of the base!
