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.

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.
