About These Birds
Green-winged Teal
A small dabbling duck, the North American counterpart to Common Teal. Males have a rich chestnut head with broad metallic green eye-stripe, finely vermiculated grey body, and a distinctive white vertical breast stripe. One of North America's most abundant ducks.
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.
