The Tufted duck is a medium-sized diving duck, smaller than a mallard. It breeds in the UK across lowland areas of England, Scotland and Ireland, but less commonly in Wales, with most birds being residents. Numbers increase in the UK in winter because of birds moving to the UK from Iceland and northern Europe.
It can be found on inland lakes, flooded gravel pits, reservoirs and slow-flowing rivers and avoids deep water.
Its diet consists of molluscs, insects and some plants.
The male is generally silent but gives a low whistle during courtship. The female makes a gruff growling call.
