Habitat Comparison
Mandarin Duck
Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.
Magellanic Steamerduck
Rocky coastal shores, kelp-fringed channels, and sheltered bays of Patagonian Chile and Argentina. Flightless; confined to coastline. Nests on rocky shorelines. Uses wings to propel across water surface.
Song & Call Comparison
Mandarin Duck
Male gives a low whistled 'hib' or 'weep'. Female utters a soft quacking 'kek'. Generally quiet and secretive. No loud territorial song; vocalizations subtle and brief.
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.
