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.

Barau's Petrel

38 cm, wingspan 96 cm. Dark above with white forehead; white below with dark carpal bar and partial collar. Breeds only on Réunion; Endangered with around 4,000 pairs. Threatened by light attraction of fledglings; conservation lighting campaigns reduce strandings. Migrates to Indian Ocean.
