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.
Scripps's Murrelet
Scripps's Murrelet, 22–24 cm, breeds in crevices on Channel Islands off southern California. White underparts contrasting with dark grey upperparts; white split extends up flanks. Nocturnal at colonies. Chicks lead-march to sea within 2 days of hatching. Piscivore; threatened by light pollution and introduced predators.
