About These Birds
Cape Teal
A small pale grey teal with pink bill, orange-red eye, and green speculum. The palest duck in Africa. Found on saline and alkaline lakes and pans across sub-Saharan Africa. Nomadic; follows shifting water availability. Feeds by filter-dabbling.
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.
