Résumé :	The winter was cold with snow cover from the end of November till the end of December. Conditions then returned to normal, with open water surfaces thawed out by mid-January. During December, these peculiar conditions resulted in substantial decreases in numbers notably of dabbling ducks. Globally, the numbers of Anatidae and other waterbirds were near-average. There were large numbers of over-wintering Common Pochards Aythya ferina and Tufted Ducks Aythya fuligula, Common Egrets Ardea alba and Eurasian Coots Fulica atra, and increased numbers of Whooper Swan Cygnus cygnus and Great Cormorant Phalacrocorax carbo.On the other hand, the numbers of various other species was average or weak (Eurasian Teal Anas crecca, Little Grebe Tachybaptus ruficollis and Great Crested Grebe Podiceps cristatus, Grey Heron Ardea cinerea, Common Moorhen Gallinula chloropus...) and no significant arrivals of northern species such as Common Goldeneye Bucephala clangula and Mergansers were recorded.
