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.
Little Shearwater
25–30 cm. Small shearwater; dark above with white underparts and extensive white on face and sides of neck. Breeds Canary Islands, Madeira, and southern hemisphere islands; ranges in adjacent oceans. Feeds on small fish and squid; fast fluttering flight close to water.
