About These Birds
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.
Flying Steamerduck
The only flying species among the four steamerducks, with grey plumage, rufous-washed head, and an orange-yellow bill. Can fly strongly unlike its relatives. Found in Patagonian freshwater and coastal habitats. Highly territorial; pairs defend stretches of river or lakeshore aggressively.
