About These Birds
Mexican Duck
A large dabbling duck resembling a female Mallard with an olive-green bill, blue speculum, and orange-yellow legs. Found in highland lakes and marshes of Mexico and the southwestern United States. Often considered a Mallard subspecies; sometimes treated as distinct due to limited hybridization.
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.
