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.
Whooper Swan
A large all-white swan with a long neck and a distinctive yellow-and-black bill pattern—a large yellow wedge extending to the nostrils. The national bird of Finland. Calls with a bugling whooping resonance. Breeds in Eurasian subarctic; winters in northwest Europe and East Asia.
