About These Birds
Brazilian Teal
A small compact teal with brown plumage, red bill and legs, and males with a distinctive powder-blue speculum. Common in tropical lowland South America. One of the most widespread ducks in Brazil. Found in a wide range of wetland types from flooded forest to open lakes.
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.
