About These Birds

Blauhäher

Der Blauhäher ist ein mutiges, intelligentes Mitglied der Rabenvögel, bekannt für sein auffälliges Gefieder und seine lauten Rufe. Als wichtiger Verbreiter von Eichen versteckt er jeden Herbst Tausende Eicheln. Zu seinem komplexen Sozialverhalten gehört das Nachahmen von Bussardrufen, um andere Vögel von Futterstellen zu vertreiben.

Elster

Die Elster zählt zu den intelligentesten Tieren der Erde und war das erste Nicht-Säugetier, dem eine Selbsterkennung im Spiegel nachgewiesen wurde. Diese dreisten Rabenvögel bauen kunstvolle, kuppelförmige Nester aus Zweigen und gelten als Liebhaber glänzender Gegenstände, wenngleich dieser Ruf möglicherweise übertrieben ist.
