About These Birds
Tristan Albatross
Tristan Albatross, 100–110 cm, wingspan 250–300 cm, breeds only on Gough Island in the South Atlantic — one of the world's most isolated islands. Critically Endangered; mouse predation on eggs and chicks is causing severe decline. Pelagic across the South Atlantic; piscivore and squid feeder.
Wanderalbatros
Der Wanderalbatros besitzt mit bis zu 3,5 Metern die größte Flügelspannweite aller lebenden Vögel. Diese ozeanischen Nomaden können die Erde umrunden und legen mithilfe des dynamischen Segelflugs bei minimalem Flügelschlag über 120.000 km im Jahr zurück. Paare bleiben ein Leben lang zusammen und können über 60 Jahre alt werden.
