Sarcelle d'hiver
The location of the lakes, at the meeting point of three rivers makes it an ideal stop off point for migrating birds. Different birds use the reserve at different times of the year. In winter ducks such as mallard, Eurasian teal, wigeon, common goldeneye and northern shoveler are on the lake. In the early summer lapwing, oystercatcher, redshank and ringed plover breed in the reserve. Other birds that may be on the reserve include the short-eared owl, skylark, Canada goose and song thrush. Otters and water voles are amongst the mammals in the reserve.
