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.
