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.

Africa's largest waterfowl, a massive goose-like bird with iridescent black-and-white plumage, a large red bill knob, bare red facial skin, and prominent bony wing spurs. Males can weigh up to 10 kg. Territorial; feeds on aquatic vegetation and agricultural crops across sub-Saharan Africa.
