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.
Black-necked Swan
A large elegant swan with pure white body plumage and a contrasting jet-black neck and head, a red bill with bright red caruncle, and a white stripe behind the eye. Native to southern South America. Unique coloration makes it unmistakable. Feeds on aquatic vegetation by upending.
