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.
Plumed Whistling-duck
A large whistling-duck with long buff flank plumes extending beyond the folded wings, brown body, pink bill, and upright posture. Endemic to Australia. Gregarious, forming large grazing flocks on grasslands near water. Feeds mainly on grasses and sedges rather than aquatic plants.
