About These Birds
Ferruginous Duck
A small compact diving duck. Males have rich chestnut-brown head and body, white eye, and white undertail; females are duller. Found across Eurasia and Africa. Locally common on Mediterranean and Central Asian lakes; population declining. Near Threatened globally.
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.
