In 2018-2019, the water bird counts took place during another mild winter, with colder conditions limited to only a part of the month of January.The total number of native Anatidae in January was close to the average for the past decade. The Mallard Anas platyrhynchos was the commonest species, far outstripping the numbers of Tufted Duck Aythya fuligula and of Gadwall Anas strepera; numbers of the latter show a long term increase. Long term decreases continued in the numbers of Common Pochard Aythya ferina, of Whooper Cygnus Cygnus and Bewick's Swans Cygnus columbianus and of Smew Mergellus albellus. Shovelers Anas clypeata and Goosanders Mergus merganser were relatively numerous, the numbers of Common Goldeneye Bucephala clangula were about average. Non-native waterfowl were generally numerous. As concerns other water fowl than Anatidae, there were only a few Great Crested Grebes Podiceps cristatus, but there were numbers of the Great Cormorant Phalacrocorax carbo and Great White Egret Ardea alba. Worthy of special note is the relatively long stay of a Pygmy Cormorant Microcarbo pygmaeus.
