Cormorants (Kormorane) are fish-eaters and excellent divers, some have been found to dive as deep as 45 metres. They have relatively short wings due to their need for economical movement underwater, and consequently have the highest flight costs of any flying bird. These were observed at the Islands of Cies, National Park Galicia, but they range around the world, except for the central Pacific islands. (https://en.wikipedia.org/wiki/Cormorant)
