About These Birds
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.
Rhinoceros Auklet
Rhinoceros Auklet, 37–41 cm, breeds colonially in burrows on North Pacific islands from California to Japan. Adults develop a prominent horn at bill base in breeding plumage plus white facial plumes. Nocturnal at colonies. Piscivore; dives up to 50 m for sand lance and herring. Winters at sea.
