About These Birds
Lesser Whistling-duck
A small warm brown whistling-duck with chestnut upper-tail coverts, a pale face, and dark brown cap. The most widespread and common whistling-duck in Asia. Found in freshwater wetlands from the Indian subcontinent to Southeast Asia. Nests in holes in trees and sometimes in thatched roofs.
Mandarinente
Die Mandarinente gilt weithin als die schönste Ente der Welt. In der ostasiatischen Kultur symbolisiert sie Liebe und Treue, da sie feste Paarbindungen eingeht. Anders als die meisten Enten nistet die Mandarinente in Baumhöhlen bis zu 9 Meter über dem Boden, sodass die erst einen Tag alten Küken zu Boden springen müssen.
