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.

A small ornate teal. Males have a pink-chestnut breast, grey flanks, and grey-brown back with dark green speculum; females are brown with distinctive white eye-ring and spotted flanks. Found in subtropical forests of South America. Nests in tree cavities. Perches and roosts in trees.
