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.
Guadalupe Murrelet
Guadalupe Murrelet, 22–24 cm, breeds only on Guadalupe Island off Baja California. Very similar to Scripps's Murrelet but with more extensive white on the face. Critically Endangered; fewer than 1,000 individuals; nesting habitat threatened by feral cats and goats (now being controlled). Piscivore.
