21 inches. Male and female identical in appearance. Duck with piped brown feathers beige or white. The head is clearer with a dark cap well marked and eyes outlined in black. The long scald which overcomes the eye evokes an eyebrow; it is probably the origin of the common name of the species. The wing mirror is emerald green.

They feed on seeds and other plant materials but also insects, snails and earthworms found on mudflats and wet grasslands.

The nest is built on the ground, in the fork of a tree or in a natural cavity. It is composed of plant fragments and feathers. Spawning is made from June to September light buff colored eggs and a size of 53 x 38 mm. The reproduction was studied in New Zealand on another subspecies. The eggs are incubated by the female for 27-28 days. In New Zealand, reproduction occurs from August to December and even early June in the northern part of that country. In French Polynesia, active nests were observed from April to July.
