About These Birds
Sunda Teal
A medium-sized brown teal with pale spotting, green speculum, and a high domed forehead giving the head a distinctive shape. Found on Indonesian islands from Java and Sulawesi to Lesser Sundas. Non-migratory island species. Threatened by hunting and wetland drainage.
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.
