About These Birds
Andaman Teal
A small dark brown teal with a white throat and chin patch, green speculum, and dark bill. Endemic to the Andaman and Nicobar Islands in the Bay of Bengal. Vulnerable; threatened by habitat loss and hunting. One of the least-known ducks in Asia.
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.
