Description

Size 47-61cm.

Dark brown duck with light scalloping on wings. Blackish crown, buff face with a dark line though the eye and a chin strap. Iridescent blue/green wing panel and white under wing with dark trailing edges noticeable in flight. Feet and legs yellow/green.

Feeding Habits

Dabbling duck (head down-tail up). Aquatic insects and larvae, seeds and floating vegetation (taken from or just below the water surface).

Breeding

Nest is a down-lined tree hollow or grass cup in dense grass or reeds. They occasionally use old nests of other water birds. They breed Jan-April, incubation 20 days. The female is the only carer.

Places to Look

Wetlands, rivers, roadside ponds, freshwater and brackish swamps, parks and tidal mudflats.

Threats

Continuing drainage of swamps. Interbreeding with the introduced Mallard may lessen its ability to survive droughts.
