Unmistakable, with large feet evolved for wading on lily pads and breeding plumage marked by the elongated black central tail feathers, white front, wing, and silky golden nape.  Body is chocolate brown, with a white face; the back of the crown is black with white stripes running down the sides of the neck that separate the white of the front of neck and the golden yellow of the nape. 

The wings are predominantly white; in flight the white wing shows a black border formed by black on the outermost primaries and the tips of the outer secondaries and the primaries. The wing coverts are pale brown and the scapulars may be glossed green or purple. 

Found in tropical Asia from Yemen to the Philippines. Females are larger than the males and are polyandrous, laying several clutches that are raised by different males in their harem.
