About These Birds
Bar-headed Goose
Famous as one of the world's highest-flying birds, crossing the Himalayas at altitudes exceeding 7,000 m during migration. Medium-sized, pale grey with two distinctive black bars on the white head. Breeds on high-altitude lakes; winters in South Asian wetlands. Specialized haemoglobin enables high-altitude flight.
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.
