Article summary

The winter 2011-2012 was mild, except for a major cold wave between end Januray and mi-February. The relatively mild weather supported the wintering of birds such as Cattle Egret Bubulcus ibis and Little Egret Egretta garzetta and unusually high numbers of Gadwall Anas strepera and Shoveler Anas clypeata. The high numbers of Tufted Duck Aythya fuligula and Common Coot Fulica atra, as well as the continuous increase of Canada Goose Branta Canadensis and Great White Egret Casmerodius albus, are also worth mentioning.Some birds were unusually scarce: Winter Teal Anas crecca, Pochard Aythya ferina and the two species of snipes. Some species like the Common Merganser Mergus merganser showed an influx during the cold wave.
