The Shelducks, genus Tadorna, are a group of large birds in the Tadorninae subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.
A shelduck is approximately 58.5 cm in length and has a white plumage with bold brown and black markings. It can be found from the British Isles across, Europe and Asia to Eastern China.
The shelducks are a group of larger often semi-terrestrial waterfowl, which can be seen as intermediate between geese (Anserinae) and ducks. Their diet consists of small shore animals (winkles, crabs etc) as well as grasses and other plants.
