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.
Black-headed Jay
The Black-headed Jay is a medium-sized, boldly patterned jay with a black head and face, gray body, and bright blue-and-white wing markings. It inhabits coniferous and mixed forests of the Himalayas from northern Pakistan through India to Bhutan, typically at elevations between 1,500 and 3,500 meters. It feeds on acorns, seeds, insects, and small vertebrates, and is known to cache food for winter.
