About These Birds

A medium-sized duck. Males have a creamy-white forehead blaze, broad green eye-stripe, pink-brown body, and white shoulder patch; females are warm brown. Common in North America; winters in coastal wetlands and agricultural land. Grazes on grass and aquatic plants.
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.
