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.

Wanderfalke

Der Wanderfalke ist das schnellste Tier der Erde und erreicht bei seinem charakteristischen Sturzflug auf Beute Geschwindigkeiten von über 389 km/h. Wie der Weißkopfseeadler erlitt auch der Wanderfalke durch DDT dramatische Bestandseinbrüche, konnte sich jedoch dank intensiver Schutzprogramme erholen. Die Art hat sich bemerkenswert gut an städtische Lebensräume angepasst.
