About These Birds
Razorbill
Razorbill, 37–39 cm, is an Atlantic alcid with a deep, laterally compressed bill crossed by a white vertical bar. Breeds on Atlantic cliff colonies from Maine to Greenland and Iceland to Norway; winters at sea. Dives to over 100 m pursuing fish. Strongly monogamous; pairs reunite annually at colonies.
Papageitaucher
Der Papageitaucher, oft als Clown der Meere bezeichnet, ist ein charismatischer Seevogel, der in Höhlen an nördlichen Meeresklippen brütet. Dank rückwärts gerichteter Dornen am Gaumen kann er bis zu einem Dutzend Fische quer im Schnabel tragen. Klimawandel und Überfischung bedrohen sein Nahrungsangebot und führen zu Bestandsrückgängen.
