About These Birds

Virginia-Uhu

Der Virginia-Uhu ist die kraftvollste und am weitesten verbreitete Eule Amerikas und trägt daher den Beinamen Tiger des Himmels. Er zählt zu den frühesten Brutvögeln und legt seine Eier oft schon im Januar, wenn noch Schnee liegt. Der Virginia-Uhu ist ein gefürchteter Jäger, der regelmäßig Beute erlegt, die bis zu dreimal so schwer ist wie er selbst.

Mandschurenstorch

Der Mandschurenstorch ist eine der am stärksten gefährdeten Storchenarten; in freier Wildbahn leben noch weniger als 3.000 Individuen. Einst war er in ganz Ostasien weit verbreitet, ging jedoch durch die Trockenlegung von Feuchtgebieten und den Einsatz von Pestiziden dramatisch zurück. Wiederansiedlungsprogramme in Japan und Korea konnten bemerkenswerte Erfolge erzielen.
