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.
Magellanic Diving-petrel
20–24 cm. Dark above, white below; narrow white tips to secondary feathers. Breeds southern Chile and Argentina (Strait of Magellan and Falklands). Year-round resident in coastal cold waters. Feeds on fish and crustaceans by pursuit-diving; nests in burrows on coastal islands.
