-17–23cm, females are larger than the males. Chestnut back and wing coverts, black body, green yellow flight feathers, yellow bill, legs and very long toes. Juveniles have strikingly different plumage, with white underparts and brown uppers. The head is white with a brown crown and eye stripe. Only the large feet and the bill are good indicators that this is the same species. The wings are often raised when on the ground or floating vegetation, showing bright translucent greenish-yellow flight feathers.+[[Image:IMG 47203.jpg|thumb|350px|right|Female<br />Photo by {{user|jeffworman|jeffworman}}<br />Sierpe River, [[Costa Rica]], April 2017]]
