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.
Northern Shoveler
A medium-sized duck with a dramatically large spatula-shaped bill perfectly adapted for filter-feeding. Males have an iridescent green head, white breast, chestnut flanks, and sky-blue wing patches. Highly migratory; one of the Northern Hemisphere's most widespread ducks.
