Aythya fuligula Linnaeus, 1758 ♀
Common names : Tufted Duck [En], Fuligule morillon [Fr], Kuifeend [Nl], Reiherente [De], Moretta [It], Porrón moñudo [Es], Tepeli patka [Tu]

Tubize, BRABANT ● Belgium

IUCN Status : Least Concern (LC)

Description: The adult male is all black except for white flanks and a blue-grey bill. It has an obvious head tuft that gives the species its common name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks.

Biology: These birds feed mainly by diving, but they will dabble. They eat molluscs, aquatic insects and some plants and sometimes feed at night.

Habitat: Their breeding habitat is close to marshes and lakes with plenty of vegetation to conceal the nest. They are also found on coastal lagoons, the seashore, and sheltered ponds.

Distribution: The Tufted Duck breeds widely throughout temperate and northern Eurasia. It occasionally can be found as a winter visitor along both coasts of the United States and Canada. It is believed to have expanded its traditional range with the increased availability of open water due to gravel extraction, and the spread of freshwater mussels, a favourite food. These ducks are migratory in most of their range, and winter in the milder south and west of Europe, southern Asia and all year in most of the United Kingdom. They will form large flocks on open water in winter.

Threats: The species is threatened by habitat degradation due to oil pollution, drainage, peat-extraction and changing land management practices (e.g. decreased grazing and mowing in meadows leading to scrub over-growth and agricultural intensification) in breeding areas. It also suffers decreased reproductive success as a result of disturbance from increased recreational use of inland waterbodies, machinery noise from urban development, hunting and predation by American mink Neovison vison on islands. The species is susceptible to avian influenza so may be threatened by future outbreaks of the virus.
