The eastern spot-billed duck is a large mottled-brown dabbling duck with a yellow-tipped black bill and blue-green speculum, but without the Indian species' red bill-base spots. It breeds in eastern Russia and East Asia and some populations migrate south to Southeast Asia. On lakes, marshes, rivers and rice fields it dabbles for aquatic vegetation, seeds and invertebrates (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
