About These Birds
Indian Spot-billed Duck
A large brown dabbling duck with distinctive yellow-tipped black bill, red spot at the bill base, white tertials, and blue-green speculum. Common across South and Southeast Asia. Found in a wide range of freshwater habitats. Largely non-migratory.
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.
