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.
Yelkouan Shearwater
30–38 cm. Brown-black above, white below; similar to Manx but darker with brown flanks and dusky undertail. Breeds Mediterranean islands and coasts. Non-breeding range in eastern Mediterranean and Black Sea. Vulnerable; threatened by introduced predators and light pollution. Feeds on fish and squid.
