Penguins are birds that live in the water and on land. They cannot fly, but they are excellent swimmers. They have webbed feet and short wings, which they use for swimming. There are several kinds of penguins. They love in both warm and cold climates, but only in waters south of the equator.
Penguins spend most of their lives in the oceans.
They live on the land only when laying their eggs and raising their young. Penguins are sociable animals and live and play together. They nest in colonies called rookeries. Some of these rookeries have as many as million birds. Penguins propel themselves through the water with flying movements of their flippers.
