About These Birds
Flesh-footed Shearwater
41–45 cm, wingspan 99–107 cm. All-dark sooty-brown with pale flesh-coloured feet and yellowish bill base. Breeds southern Indian Ocean islands and SW Australia; ranges to North Pacific. Near Threatened; bycatch concern. Feeds on fish and squid; follows fishing vessels.
Eissturmvogel
Der Eissturmvogel ist ein langlebiger Seevogel, der über 40 Jahre alt werden kann. Er verteidigt sein Nest, indem er Eindringlinge mit übel riechendem Magenöl bespuckt, das die Federn von Fressfeinden verkleben und deren Wasserdichtigkeit zerstören kann – mitunter mit tödlichen Folgen. Der Eissturmvogel hat sein Brutgebiet in den letzten zwei Jahrhunderten drastisch nach Süden ausgedehnt.
