Hesperornis or Western Diver - Prehistoric Animals
The penguins are well known for their diving and swimming under water with their wings which are more like paddles. In ancient times, big diving birds lived in the sea of Western America, and these had practically no wings at all, but they swam with big, paddle-shaped feet, and caught fish with their beaks. As their legs were not made for walking and they could not fly they spent most of their lives in the water.
