Sarcelle d'hiver
During the winter months the flooded meadows attract wintering wildfowl such as northern pintail, Eurasian teal and Eurasian wigeon, as well as Bewick's swan. As the floodwater recedes the bare mud around the ditches and scrapes, and the area of fen provide breeding and foraging habitat for waders such as common snipe. The hay meadows at the back of the reserve are ideal for Eurasian curlew nesting. In 2010 it is reported that Eurasian oystercatchers have bred for the first time, and six pairs of northern lapwing chicks have also been seen.
