"I would go faster in sneekers" by Helgi Skulason. The picture quality is not the best but I just love the moment. Unlike most birds the puffin has solid bones. That is to stand the pressure when diving very deep. This makes them more heavy and harder to take off, espcially in calm weather. So the first part of the flight is actually a searun. Doing this he has to flap his wings up to 6 times á second.
