About These Birds
Black Scoter
A medium-sized sea duck (~1 kg) in family Anatidae, males entirely black with a bold orange-yellow knob at the bill base. Breeds on boreal and tundra lakes of North America and eastern Russia; winters coastally. Dives for mollusks and crustaceans. Near Threatened following population declines linked to habitat loss on breeding grounds.
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.
