Basstölpel
Der Basstölpel ist ein spektakulärer Sturzflugtaucher, der seine zwei Meter breiten Flügel pfeilförmig anlegt und mit bis zu 100 km/h auf das Wasser trifft. Luftsäcke unter der Haut und ein verstärkter Schädel schützen ihn vor dem Aufprall. Der Bass Rock in Schottland beherbergt über 150.000 Basstölpel – die größte einzelne Kolonie eines Seevogels weltweit.
