The species
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. Its scientific name comes from the French name Tadorne for this species. It may originally derive from Celtic roots meaning "pied waterfowl", essentially the same as the English "shelduck".
