Introduction

The Tufted Duck (Aythya fuligula) is a medium-sized diving duck in the family Anatidae. It breeds across much of temperate and northern Eurasia and migrates or disperses southwards in winter. The species is particularly recognisable for the male’s black-and-white plumage, yellow eye and narrow crest at the back of the head.

Physical Description

Tufted Ducks are compact diving ducks measuring approximately 40–47 cm in length and weighing about 600–1,020 g. Males and females differ markedly in appearance.

Adult males have a glossy black head, neck, breast and upperparts, contrasting with bright white flanks and a pale grey back. The head has a distinctive drooping crest, or tuft, which is most obvious during the breeding season. The eye is bright yellow and the bill is bluish-grey with a dark nail at the tip.

Females are mainly dark brown, with paler flanks and a shorter, less conspicuous crest. Some females show a variable pale patch around the base of the bill. Their eyes are generally yellow to yellowish-brown. Juveniles resemble females but are usually duller, with less contrast in the plumage and a less developed crest.

The species undergoes a seasonal moult, and males in eclipse plumage can temporarily appear browner and less sharply patterned than breeding males.

Range and Habitat

The Tufted Duck has a broad distribution across northern and temperate Europe and Asia. It breeds in areas extending from the British Isles and Scandinavia through northern and eastern Europe to Siberia and parts of northern and central Asia. Many populations migrate, although some birds remain resident where water remains ice-free.

In winter, birds move to milder parts of western and southern Europe, the Mediterranean region, central Africa, the Indian subcontinent and Southeast Asia. It is an uncommon to rare visitor in North America, where it is usually found singly among flocks of scaup.

Breeding habitat includes freshwater lakes, ponds, marshes, reservoirs and slow-moving waters with emergent or marginal vegetation. During migration and winter, Tufted Ducks also use large lakes, sheltered coastal waters, estuaries and brackish lagoons. They often gather in sizeable flocks, particularly where suitable feeding areas are available.

Behaviour and Diet

Tufted Ducks are strong divers. They commonly feed by diving from the surface and may spend long periods resting between feeding bouts. They are often sociable, especially outside the breeding season, and may associate with other diving ducks.

Their diet varies with location and season. It includes aquatic molluscs, especially freshwater mussels, as well as crustaceans, aquatic insects and other invertebrates. Plant material, including seeds, leaves, shoots and other submerged vegetation, is also eaten. In some European wintering areas, zebra mussels (Dreissena polymorpha) form an important food source.

Breeding generally takes place from late spring into summer. The female builds a nest close to water, usually among dense vegetation or on an island, and typically lays 8–11 eggs, although smaller and larger clutches occur. She incubates the eggs for about 25 days. The male commonly leaves the breeding area to join moulting flocks after pairing and incubation has begun.

The ducklings are precocial and covered in down when they hatch. They leave the nest soon afterwards, can feed themselves and remain under the female’s guidance while they grow. Young birds usually require approximately 45–50 days to become fully fledged.

Identification Tips

  • Look for a compact diving duck with a short neck and rounded body.
  • A breeding male is mainly black with bright white flanks, a yellow eye and a narrow, drooping crest.
  • A female is dark brown, usually with paler flanks, a shorter crest and sometimes a pale patch at the base of the bill.
  • Both sexes show a conspicuous white wing stripe in flight.
  • Compared with Greater Scaup, Tufted Ducks usually have a darker, blacker back and a more obvious crest. Females are generally darker overall and have a smaller, less sharply defined pale facial patch.
  • Compared with Common Pochard, the Tufted Duck is smaller and more compact. The male lacks the Pochard’s reddish head and has a black head with white flanks instead.

Conservation Status

The Tufted Duck is classified globally as Least Concern on the IUCN Red List. Its large range and substantial population provide considerable overall security, and the global population trend is generally described as stable. Regional trends are not uniform, however, and some populations have declined while others are stable or increasing.

Important local pressures include the loss and degradation of wetlands, pollution, disturbance at breeding and wintering sites, changes in water levels and food availability, and the effects of climate change on migration, drought and freezing conditions. Conservation measures include protecting wetlands, maintaining suitable aquatic vegetation, monitoring breeding and wintering populations, and managing pollution and disturbance in important sites.

Frequently Asked Questions

Where does the Tufted Duck live?

The species breeds across northern and temperate Eurasia and winters in milder parts of Europe, Africa, southern Asia and Southeast Asia. It uses freshwater lakes, marshes, reservoirs, estuaries and sheltered coastal waters.

How can you identify a male Tufted Duck?

A breeding male is mostly glossy black with bright white flanks, a yellow eye and a narrow crest at the back of the head. The combination of black-and-white plumage and the crest is distinctive.

What does the Tufted Duck eat?

It eats aquatic molluscs, crustaceans, insects and plant material. Freshwater mussels can be especially important during winter, while seeds, shoots and other aquatic vegetation supplement the diet.

Do Tufted Ducks migrate?

Many Tufted Ducks migrate or disperse between breeding and wintering areas. Some remain resident where suitable water remains open throughout winter, while northern populations generally move southwards.

Where does the Tufted Duck build its nest?

The female usually nests close to water, concealed in dense vegetation or on an island. She lays a typical clutch of 8–11 eggs and incubates them for about 25 days.

Are Tufted Ducks endangered?

No. The species is currently classified as Least Concern globally. Nevertheless, local populations can be affected by wetland loss, pollution, disturbance and changing environmental conditions.
