The adult male has a red bill, large white crescent above the eye and reddish face and "whiskers". The male's breast is purple with two vertical white bars, and the flanks ruddy, and he has two orange "sails" at the back (large feathers that stick up like boat sails). The female is similar to the female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.
