About These Birds
Bismarck Crow
The Bismarck Crow is a glossy black crow endemic to the Bismarck Archipelago and adjacent islands in Papua New Guinea. Like other crows, it is highly intelligent and omnivorous, feeding on carrion, fruits, invertebrates, and small vertebrates. It inhabits forest, forest edges, and coastal areas.
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.
