About These Birds
Sunda Teal
A medium-sized brown teal with pale spotting, green speculum, and a high domed forehead giving the head a distinctive shape. Found on Indonesian islands from Java and Sulawesi to Lesser Sundas. Non-migratory island species. Threatened by hunting and wetland drainage.
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.
