Other species with numbers of over 100 000 birds were Tufted Duck and Scaup. A synopsis of the abundance of waterfowl species counted in The Netherlands during three cold winters (1985-87) and during three very mild seasons (l988-90)is given in table 2. In 1990,49 areas held one or more species with at least 1%of the NW-European flyway population. Internationally important numbers of Bewick's Swans were counted in 22 areas. The total number of Bewick's Swans in The Netherlands amounted to 13 000, which is 76.5% of the total population wintering in NW-Europe. ##### Little Grebe Tachybaptus ruficollis Great Crested Grebe Podiceps cristatus Mute Swan Cygnus olor Bewick's Swan Cygnus bewickii Whooper Swan Cygnus cygnus Common Shelduck Tadorna tadorna Eurasian Wigeon Anas penelope Gadwall Anas strepera Common Teal Anas crecca Mallard Anas platyrhynchos Northern Pintail Anas acuta Northern Shoveler Anas clypeata = Spatula clypeata Red-crested Pochard Netta rufina Common Pochard Aythya ferina Ferruginous Duck Aythya nyroca Tufted Duck Aythya fuligula Greater Scaup Aythya marila Common Eider Somateria mollissima Long-tailed Duck Clangula hyemalis Black Scoter Melanitta nigra Velvet Scoter Melanitta fusca Common Goldeneye Bucephala clangula Smew Mergellus albellus Red-breasted Merganser Mergus serrator Goosander Mergus merganser Common Moorhen Gallinula chloropus Eurasian Coot Fulica atra
