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.

North America's largest native waterfowl and one of the heaviest flying birds, with all-white plumage, a long neck, and all-black bill. Named for its resonant bugling call. Recovered from near extinction in the 20th century through active conservation. Breeds in northern wetlands.
