About These Birds
Küstenseeschwalbe
Die Küstenseeschwalbe hält den Rekord für die längste bekannte Wanderung im Tierreich und legt jährlich rund 70.000 km zwischen Arktis und Antarktis und zurück zurück. Über ihre rund 30 Lebensjahre hinweg fliegt sie damit rechnerisch das Äquivalent von drei Rundreisen zum Mond. Dieser bemerkenswerte Vogel erlebt mehr Tageslicht als jedes andere Lebewesen der Erde.
