About These Birds
Egyptian Goose
A large conspicuous sheldgoose-like bird with brown-and-white body, dark eye patches, a chestnut patch on the chest, and pink bill and legs. Native to Africa and the Nile Valley; widely introduced to Europe. Aggressive and territorial; found in urban parks. Feeds by grazing on grass.
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.
