Penguins are Flightless Birds. However, like marine mammals, they are able to swim underwater for long periods. Rather than milk, they feed their young regurgitated fish. In some species, notably the Emperor penguins, the male (who fasts while incubating the egg alone) can regurgitate a fatty substance for a newborn to eat in lieu of food.
