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.
Song & Call Comparison
Harlequin Duck
Male gives a squeaky, mouse-like squeal; female produces a guttural, grunting call. The male's bizarre, high-pitched squealing call is completely unexpected in such a compact seaduck.
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.
Geographic Range & Migration
Harlequin Duck
Breeds on fast-flowing rivers in Iceland, Greenland, and northern North America. Winters along rocky Pacific and Atlantic coasts south to California.
Mandarin Duck
Native to East Asia including eastern Russia, China, Japan, and Korea. Feral populations established in Britain and western Europe.

About These Birds
Harlequin Duck
A compact sea duck (~550 g) in family Anatidae, males strikingly patterned in slate-blue with chestnut and white markings. Breeds along fast-flowing mountain streams in North America, Greenland, and Iceland; winters on rocky surf-swept coastlines. Feeds on aquatic invertebrates. Least Concern with stable populations across its range.
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.
