About These Birds
Chiloe Wigeon
A large boldly patterned wigeon with a metallic green head, white face, black breast, grey flanks with white barring, and a bright orange-yellow bill. Endemic to southern South America. Highly territorial; pairs defend lake territories. Named for Chiloé Island in Chile.
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.
