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-billed Magpie
The Black-billed Magpie is a striking, long-tailed corvid of western North America, with bold black-and-white plumage and an iridescent blue-green sheen on the wings and tail. It inhabits open country with scattered trees, riparian woodlands, and suburban areas from Alaska south to California and east to the Great Plains. It is omnivorous, feeding on carrion, insects, fruits, seeds, and small vertebrates.
