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.
Siberian Scoter

Breeds near boreal lakes and winters in coastal seas of East Asia. Feeds by diving for benthic mollusks and crustaceans. Least Concern; recently split from White-winged Scoter as a distinct species.
