Mandarin Duck

The Mandarin Duck is widely regarded as one of the most visually stunning waterfowl species in the world. Native to East Asia, but with established feral populations in Europe and North America, this species is closely related to the North American Wood Duck. While males display a dazzling array of colors and unique sail-like feathers during the breeding season, females are elegantly patterned in muted grey and brown tones. They are perching ducks, often nesting in tree cavities high above the ground and resting on branches overhanging open water.

Male breeding plumage is unmistakable. They feature a reddish face with a broad, white sweep curving behind the dark eye, a large crest of green, copper, and purple running down the neck, a purple breast with two vertical white bars, and two orange 'sail' feathers (modified secondaries) that rise vertically from their back. Females and eclipse males are much more subdued: grey-brown overall, with a distinctive white eye-ring that extends back as a narrow stripe, small white spots on the underparts, and a pale grey bill. They resemble female Wood Ducks but can be distinguished by their cooler grey color, smaller, rounder white spots on the flanks, and a narrower, cleaner white eye-ring.

Mandarin Ducks prefer deciduous or mixed woodlands adjacent to shallow water bodies, such as ponds, slow-moving rivers, swamps, and flooded parks. In their native range of East Asia (including eastern Russia, China, Japan, and Korea), they breed in forested areas and migrate south to eastern China and southern Japan for the winter. Due to escapes from private collections, robust, self-sustaining feral populations have settled in the United Kingdom, Western Europe, and localized spots in North America, particularly northern California and the Pacific Northwest.

Mandarin Ducks are shy, secretive birds that frequently seek cover under overhanging bankside vegetation. Unlike most ducks, they are highly adapted to perching in trees and can navigate branches with ease.

Feeding: They feed by dabbling in shallow water or walking on land. In autumn and winter, they rely heavily on acorns and other nuts, which they swallow whole. During the spring, they switch to a diet rich in insects, snails, and aquatic plants.

Vocalizations: Males produce a rising, wheezy whistle, used during territorial displays and flight. Females make a sharp, repetitive clucking call when disturbed or when calling to their ducklings.

Nesting: They are cavity-nesters, selecting tree holes up to 10 meters off the ground near water. Upon hatching, the ducklings must bravely leap from the tree cavity to the forest floor below, cushioned only by the leaf litter, before following their mother to the safety of nearby water.
