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.
Salvin's Prion
25–28 cm, wingspan 57–63 cm. Similar to Broad-billed Prion but bill intermediate in width; blue-grey above with dark W-wing mark. Breeds Crozet and Marion islands in Indian Ocean. Feeds on crustaceans by filter-seizing at surface. Distinguished from congeners mainly by bill width.
