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.
