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.
Cape Shoveler
A medium-sized shoveler with a characteristic large spatula-shaped bill. Males have yellow-orange eyes, brown head, and spotted brownish body; females are mottled brown. Endemic to southern Africa. Found mainly on the Western Cape's lakes and saline pans.
