Recognized in all plumages by its rounded head, steep forehead, short neck and contrasting white belly. Males with brown head and light yellow forehead, pinkish breast and grey body. Adult males with big white patch on forewing. Female mostly brown with bluish bill. Tail rather long and pointed, and wings narrow. Quite pale underwings, but not completely white like American Wigeon.

Male: a pleasant high pitched whistle "piiiiuuu", rapidly rising in pitch and then falling. Quite vocal. Female: a harsh "kraaa kraaa kraa" more like female diving-ducks than other dabbling-ducks.
