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.

Rosalöffler

Der Rosalöffler ist die einzige Löfflerart Amerikas und einer der auffälligsten Watvögel der westlichen Hemisphäre. Wie bei Flamingos stammt seine rosa Farbe von Carotinoid-Pigmenten aus seiner Beute an Krebstieren. Im 19. Jahrhundert wegen seiner Federn fast bis zur Ausrottung bejagt, haben sich die Bestände seither erheblich erholt.
