About These Birds
Lesser White-fronted Goose

One of Europe's most endangered geese; wild population now extremely small. Breeds in Arctic Scandinavia and Siberia; winters in the Middle East and eastern Asia.
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.
