About These Birds
Streaked Shearwater
48 cm, wingspan 122 cm. Large shearwater; brown-streaked white head and neck; brown above, white below. Breeds Japan and islands of East Asia; migrates south to Australia and Indian Ocean. Feeds on fish and squid; forms large flocks; the most abundant shearwater in NW Pacific.
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.
