Eastern spot-billed duck or Chinese spot-billed duck (Anas zonorhyncha) 

The eastern spot-billed duck or Chinese spot-billed duck (Anas zonorhyncha) is a species of dabbling duck that breeds in East and Southeast Asia.
This bird species is migratory, wintering in southern China and possibly Southeast Asia.

Anseriformes is derived from Latin, meaning "goose-shaped" or "goose-like," combining anser (goose) and forma (form/shape). The order constitutes ducks, geese, and swans (family Anatidae), typically known as waterfowl or wildfowl.

Anatidae is a biological family of waterfowl (ducks, geese, and swans). The term originates from New Latin Anas (stem anat-), meaning "duck," paired with the suffix -idae (denoting a zoological family). The Latin root anas traces back to the Proto-Indo-European anət- ("waterbird").

The name Anas is the Latin for "duck".

The specific epithet zonorhyncha is derived from the classical Greek words zōnē meaning "band" or "girdle" and rhunkhos meaning "bill".
