The falcated duck or falcated teal is a gadwall-sized dabbling duck from the east Palearctic.
Region
East Asia and East Palearctic
Typical Environment
Breeds across southeastern Siberia, the Amur–Ussuri basin, northeastern China, and locally in Mongolia around forest-steppe wetlands, lakes, and slow rivers. Winters mainly in eastern China, the Korean Peninsula, and Japan, with smaller numbers reaching northern Vietnam and parts of South Asia. It favors shallow freshwater wetlands, flooded meadows, rice paddies, and sluggish river margins. Vagrants are recorded in western Europe and North America, typically in winter. Habitat quality and water levels strongly influence local distribution.

Named for the male’s falcate (sickle-shaped) tertial feathers that drape over the back, the falcated duck is a striking dabbling duck of the East Palearctic. It was formerly placed in Anas but is now in the genus Mareca alongside wigeon and gadwall. It winters in large flocks and is a rare but regular vagrant to Europe and North America.

Social Behavior
Pairs form on the wintering grounds or early in spring. Nests are built on the ground in dense vegetation near water; the female incubates while the male departs after incubation begins. Outside the breeding season they gather in sizable flocks, often mixing with other dabbling ducks.
Migratory Pattern
Seasonal migrant
Song Description
Drakes give clear, whistled notes and soft wheezy calls, especially during display. Females produce lower, rasping quacks used to communicate with the brood.
