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.
Höckerschwan
Der Höckerschwan gehört zu den schwersten flugfähigen Vögeln; Männchen können bis zu 14 kg wiegen. Trotz seines englischen Namens („Mute Swan“, stummer Schwan) ist er keineswegs stumm und gibt zischende, grunzende und schnaubende Laute von sich. Höckerschwäne gehen lebenslange Paarbindungen ein, und ihre aggressive Verteidigung des Brutreviers ist bekannt.
