Tadorna tadorna (Common Shelduck)

Language: French

Wikipedia Abstract

The common shelduck (Tadorna tadorna) is a waterfowl species shelduck genus Tadorna. It is widespread and common in Eurasia, 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".
