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.

Breeds in wooded swamps, rivers, and lakes in North America, nesting in tree cavities; winters on sheltered coastal and inland waters. Uses keen underwater vision to hunt fish and crayfish. Least Concern; benefiting from nest box programs.
