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.
Goosander
The largest merganser (~1.5 kg) in family Anatidae, males with glossy green heads and salmon-flushed white bodies. Breeds along rivers and lakes in northern Europe, Asia, and North America; winters on larger rivers and reservoirs. A pursuit-diver specializing in fish, using a serrated bill for grip. Least Concern with stable Holarctic distribution.
