Description

The tufted duck is a diving bird and the male duck is slightly larger than the female. The male bird measures 40 to 50 cm in length and weighs 600 to 1,000 grams. The female duck weighs 550 to 900 grams. The wingspan is 65 to 70 cm. The male is all black except for its white flanks. The bill is greyish blue. The eyes are pale yellow. The female duck is brown with pale brown flanks.

Habitat

The tufted duck species inhabit water bodies with abundant marginal and emergent vegetation. They occur in freshwater lakes, ponds, slow moving rivers, reservoirs, sheltered coastal habitats, lagoons, tidal creeks and estuaries.

Feeding habits

The tufted duck species are omnivorous and feed mainly by diving. They feed on aquatic plants, insects, crustaceans, molluscs and other aquatic vertebrates.

Breeding

The tufted duck breed from May onwards. The nest is constructed with plant matter on floating vegetation. Ground nests are also seen concealed in bushes, close to water edge.

Distribution

The breeding populations of tufted duck occur in Europe and north Asia (Russia, China and Mongolia). Wintering populations occur in central and south Europe, Africa, Indian Subcontinent, Middle East nations and Southeast Asia.

Movement Patterns

The population in the central and northwest Europe is sedentary and the other populations are migratory. The migratory populations reach the breeding grounds from April onwards. The autumn wintering movements start from September.

Status and conservation

The global population of tufted duck species is estimated to number 2,600,000 to 2,900,000 individual birds. The population and range are extremely large. Hence there is least conservation concern. Habitat degradation, land reclamation, human activity in the breeding grounds and hunting are the conservation threats. The species is susceptible to avian influenza

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these tufted duck species and has listed them as of "Least Concern".
