The breeding male falcated duck has a glossy green-and-purple head, white throat and long curved tertial feathers that give the species its name; the female is mottled brown. It breeds in eastern Siberia and East Asia and winters farther south on marshes, lakes and flooded grassland. Birds dabble and graze for seeds, aquatic plants and invertebrates, often among other ducks (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
