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.
Baikal Teal
A strikingly beautiful teal with intricately patterned golden, green, black, and white head; pink-brown breast; and grey flanks. Breeds in Siberian taiga; winters in East Asia. Once seriously depleted, now recovering. Forms spectacular flocks of hundreds of thousands at South Korean wintering sites.
