About These Birds
Trauerschwan
Der Trauerschwan galt Europäern, die glaubten, alle Schwäne seien weiß, einst als unmöglich, was ihn zu einem berühmten philosophischen Beispiel für das Scheitern induktiver Schlussfolgerungen machte. Er ist das Wappentier von Western Australia. Trauerschwäne gehen lebenslange Paarbindungen ein, und beide Elternteile teilen sich das Brüten und die Aufzucht der Jungvögel.
Stockente
Die Stockente ist die Stammform der meisten Hausentenrassen und die häufigste und am weitesten verbreitete Schwimmente der Welt. Erpel zeigen aufwendige Balzrituale, darunter Kopfnicken und pfeifend-grunzende Rufe. Stockenten sind äußerst anpassungsfähig und gedeihen sowohl in der Wildnis als auch in städtischen Lebensräumen.
