Hardhead

Identification

The hardhead, also known as the white-eyed duck, is Australia's only true diving duck. It is a compact waterfowl, smaller than most other ducks, with a body length typically between 42–59 cm and a wingspan of 65–70 cm. Both sexes are similar in size, weighing between 525–1,100 g. The most striking feature is the eye colour: males display brilliant white eyes that stand out against their chocolate-brown plumage, while females have brown eyes. Both sexes share a fairly uniform chocolate-brown upper body, rufous flanks, and white undersides—though these white underparts are often hidden when the duck is in water. The trailing edges and almost the entire underside of the wings are white, a feature visible during flight.

Range & Habitat

Hardheads are common throughout the south-east of Australia, with particular concentrations in the Murray-Darling Basin and wetter coastal regions. They are moderately nomadic, dispersing more widely during droughts. Significant numbers occasionally reach as far as New Guinea, New Zealand, and the Pacific Islands, where they may remain and even breed for a season or two. These ducks prefer larger lakes, swamps, and rivers with deep, still water, but adapt to smaller streams, flooded grasslands, and shallow pools. They generally avoid coastal waters and are rarely seen on land, never roosting in trees. The species is widespread throughout its large range and is classified as Least Concern by the IUCN.

Behaviour & Diet

As members of the pochard group, hardheads are accomplished divers, feeding by submerging themselves with minimal disturbance—simply lowering their heads and propelling downward with powerful webbed feet. They can remain submerged for up to a minute at a time while foraging. Their diet consists of a broad range of small aquatic creatures supplemented by water weeds. Hardheads are typically silent ducks, but males produce a distinctive soft, wheezy whistle and 'whirr' call, while females have a loud, rattling 'gaark' call that is quite different from the males' quieter vocalizations.

Best Time & Places to See It

Hardheads are best encountered in the south-east of Australia, particularly around the Murray-Darling Basin and coastal wetland areas. Look for them on larger lakes, swamps, and river systems with deep, still water. They are common enough in suitable habitat to be reliably found, though their preference for deep water means they may be distant from shore. During drought periods, they may disperse to unexpected locations, making them possible to spot in unusual areas across Australia and occasionally beyond.

Photography Tips

The male's brilliant white eyes provide an excellent focal point for photography and are the species' most distinctive feature. Position yourself near deep water bodies where hardheads naturally congregate. Since these ducks dive frequently and can stay submerged for extended periods, patience is essential—be ready to capture them as they resurface. Their preference for staying on water means waterside vantage points work best. Early morning light will enhance the contrast between their chocolate-brown plumage and white eye, creating striking portrait opportunities.
