Even though the penguin is a bird, it cannot fly. It has flippers instead of wings. It also has short legs and webbed feet. The flippers and webbed feet help penguins swim. They speed through the water hunting for fish to eat. These birds are graceful swimmers. However, penguins have an odd walk on land. They shuffle, or drag their feet, on the ice as they move from place to place.
