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.
Andean Duck
A stocky stiff-tailed duck (~800 g) of family Anatidae inhabiting high-altitude Andean lakes and wetlands from Colombia to Argentina. Males are rich chestnut with a blue bill during the breeding season. Dives for aquatic plants and invertebrates in cold Andean waters. Least Concern; formerly considered conspecific with Ruddy Duck but now recognized as a distinct species.
