About These Birds
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.
Hutton's Shearwater
38 cm. Dark above; white below; larger than Fluttering Shearwater. Breeds only in alpine zone of Kaikoura Ranges, South Island, New Zealand. Endangered; very restricted inland breeding range unique among shearwaters; feeds at sea in Tasman Sea and off south Australia.
