About These Birds
Amerikanerkrähe
Die Amerikanerkrähe ist einer der bekanntesten und intelligentesten Vögel Nordamerikas. Untersuchungen zeigen, dass sie einzelne menschliche Gesichter wiedererkennen und wahrgenommene Bedrohungen an andere Krähen weitergeben können. In manchen Städten bilden sie riesige Winterschlafplätze mit bis zu Hunderttausenden Individuen.
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.
