About These Birds
Black-chested Jay
The Black-chested Jay is a medium-sized, boldly patterned jay of humid lowland forests in Central America and northwestern South America, with a blue body, black head and breast patch, and a white forehead patch. It ranges from Honduras south to Ecuador and Venezuela, inhabiting forest edges, secondary growth, and sometimes gardens. It feeds on fruits, large insects, and occasionally small vertebrates.
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.
