About These Birds
Black-collared Jay
The Black-collared Jay is a striking, medium-sized jay of Andean cloud forests in Colombia, Ecuador, Venezuela, and Peru, with deep blue plumage, a black head, and a distinctive narrow black collar. It inhabits the canopy and edges of humid montane forests at elevations between 1,500 and 3,000 meters. It feeds on insects, berries, small vertebrates, and eggs.
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.
