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.
Bryan's Shearwater
27 cm. Small shearwater; dark brown above, white below with dark smudging on flanks. Known from only a few specimens collected at Midway Atoll; Critically Endangered or possibly extinct. No confirmed breeding in decades; one of the least-known shearwaters.
