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.
Craveri's Murrelet
Craveri's Murrelet, 21–23 cm, breeds on Gulf of California islands, dispersing into the Pacific after breeding. Darkest Synthliboramphus murrelet; less white on face than Scripps's. Near Threatened; small population threatened by introduced predators on nesting islands and bycatch in gill nets.
