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.
Flying Steamerduck
The only flying species among the four steamerducks, with grey plumage, rufous-washed head, and an orange-yellow bill. Can fly strongly unlike its relatives. Found in Patagonian freshwater and coastal habitats. Highly territorial; pairs defend stretches of river or lakeshore aggressively.
