Penguins cannot fly, whereas auks, except for the now-extinct great auk, can. Also, penguins live in the southern hemisphere and auks in the northern hemisphere.
Penguins are popular at zoos, and the king penguin is the most popular penguin of all.
Very large, standing upright on its short legs, it waddles when it walks. Its head is slender and it has a long pointed beak. The king penguin breeds on islands in the south Atlantic and Indian oceans, such as the Falkland Islands and South Georgia. From October to April, thousands of birds go to these remote islands to mate. The female lays 1 egg on the ground.
