White-headed Duck

Identification

The white-headed duck is a small diving duck, measuring 43–48 cm in length and weighing 580–750 g. Males are unmistakable, with a largely white head topped by a black cap, a striking blue bill, and grey-reddish body plumage. Females are more subdued, displaying grey-brown bodies with white faces and darker bills, caps, and cheek stripes. The species' name refers directly to this distinctive white head, making males relatively easy to identify in the field.

Range & Habitat

The white-headed duck is found across Spain, North Africa, Western Asia, and Central Asia, with larger populations concentrated in western and central Asia. The species breeds in large tracts of open water including lakes, ponds, and artificial water bodies that feature dense stands of aquatic plants. These marginal vegetation zones are essential, providing both shelter and suitable nesting sites for breeding birds. Occasionally, individuals are reported well north of their established breeding range, though such records may sometimes represent escapes from waterfowl collections.

Behaviour & Diet

True to its classification as a diving duck, the white-headed duck feeds by diving and swimming underwater. It is omnivorous, though vegetable matter predominates in its diet, supplemented by animal matter. Notably, this species is reluctant to take flight, preferring to swim away when faced with a perceived threat rather than becoming airborne. This behaviour, while characteristic of the species, may make them more vulnerable to disturbance in their wetland habitats.

Best Time & Places to See It

The white-headed duck is best sought in its core breeding areas across Spain and central Asia, particularly in regions with large shallow lakes and reed-fringed wetlands. Observers should focus on open-water areas with dense marginal vegetation, where birds can feed and find shelter. Due to the species' reluctance to fly, patience and careful approach are rewarded—scanning open water with binoculars is often more effective than attempting to flush birds into flight.

Photography Tips

Photograph males in good light to capture the brilliant white head contrasting with the black cap and the distinctive blue bill. Early morning and late afternoon light will enhance the blue tones of the bill and bring out the subtle grey-reddish body plumage. Since these ducks prefer to swim away from threats rather than fly, position yourself with the sun at your back and approach slowly along the water's edge. A longer lens is recommended to avoid startling birds and to achieve detailed shots of the head markings that make this species so visually distinctive.
