Reminiscent of Mandarin Duck, most easily distinguished in all plumages by darker base to beak, and fairly narrow streaks on flanks, as well as more extensive white markings around their eyes.
Adult males are easily recognisable. Their crowns and backs are a lustrous metallic green, while their necks and breasts are dark brown and spotted. They have yellowish brown bellies and darker brown rear underparts. Their heads and throats are marked black and white. They have red irises and a red beak with a black base.
Adult females and young birds resemble Mandarin Duck females and young, though they have more white around their eyes, their heads are darker, the white patch on their beaks is shaped differently, and the spots on their flanks are less pronounced. Females have dark brown eyes and yellowish green beaks with dark bases (unlike the paler beak bases of female Mandarin Ducks).
