Size Comparison
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.
Geographic Range & Migration
Mandarin Duck
Native to East Asia including eastern Russia, China, Japan, and Korea. Feral populations established in Britain and western Europe.
Magellanic Steamerduck
Breeds in the Arctic and sub-Arctic; winters on the open Pacific Ocean from British Columbia to Baja California.

About These Birds
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
