About These Birds
Banggai Crow
The Banggai Crow is a Critically Endangered corvid of the family Corvidae found only on Peleng Island in Indonesia. 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. Deforestation and hunting have reduced its population to critically low numbers.
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.
