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.

Weighing about 175g with a wingspan of 40.2cm, it is a large all-black crow restricted to one of the world's smallest ranges for any corvid.
