The common shelduck (Tadorna tadorna) is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic , mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb .
The Australian shelduck mainly breeds in southern Australia and Tasmania and is still fairly common. [7] In the winter, many birds move farther north than the breeding range. As with other shelducks, this species has favourite moulting grounds, such as Lake George, New South Wales, where sizeable concentrations occur. The Australian shelduck's ...
[4] [5] The type species is the common shelduck. [5] The genus name comes from the French name Tadorne for the common shelduck. [6] It may originally derive from Celtic roots meaning "pied waterfowl", essentially the same as the English "shelduck". [7] A group of them is called a "dopping," taken from the Harley Manuscript.

The male has orange-brown body plumage and a paler, orange-brown head and neck, separated from the body by a narrow black collar.
Recent observations have identified changes in Israel's breeding avifauna, including the emergence of new breeding species and expansions in the breeding ranges of existing species. From 2003 to 2016, nine species were found breeding in Israel for the first time, including the common shelduck, great cormorant, and black-winged kite. [4]
Common eiders (Somateria mollissima) in the breeding season on Texel, the Netherlands. The common eider (pronounced / ˈ aɪ. d ər /) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50–71 cm (20–28 in) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia.
They are large, black-and-white or completely black, with long wings and deeply forked tails. The males have coloured inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.

Following the review of Livezey (1986), [1] several species formerly classified as aberrant dabbling ducks or as "perching ducks" were placed in the Tadorninae. mtDNA sequence analyses [2] [3] cast doubt on the allocation of several genera; many supposed dabbling ducks and one peculiar goose may more correctly belong here, while some genera believed to be close to shelducks appear to have ...
