Practice, practice, practice......

Before yellow-eyed penguin chicks leave for sea for the first time they are often seen exercising their chest and back muscles by 'flying' while standing up. Penguins 'fly' in the water: they look like birds in the air and are propelled by the same wing/flipper motion as flying birds are. The photo shows two chicks practicing - and maybe dreaming about what it would be like to fly in water!
