About These Birds
Brown Teal
A small brown duck with white eye-ring in males, dark brown plumage with chestnut flanks, and green speculum. Formerly widespread; now largely restricted to offshore islands and Northland, New Zealand. Endangered; predator control essential for survival.
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.
