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.
Japanese Murrelet
Japanese Murrelet, 26–28 cm, is a Vulnerable alcid endemic to Japan, breeding on rocky islets in the Pacific. Black head with a small white supercilium stripe; grey back. Nests in rock crevices; chicks led to sea while still tiny. Piscivore; threatened by gill-net bycatch and feral predators on islands.
