Song & Call Comparison

Magellanic Steamerduck
A loud, rattling, staccato 'kik-kik-kik' that sounds like a steam engine — hence 'steamerduck'. The wings also produce a loud churring sound as they beat the water surface.

Native to Europe and western Asia. Introduced to North America, South Africa, Australia, and New Zealand.

About These Birds
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.
Magellanic Steamerduck
A large flightless steamerduck with grey-blue plumage, a rust-orange head (male), and massive orange-red bill. Named for its habit of steaming across water using wings and feet. Found on rocky Patagonian coasts and sheltered channels. Among the world's heaviest ducks at up to 6 kg.
