Lake Madine and its satellite ponds are of prime importance for their numerous aquatic avifauna. They extend on the Woëvre plain, which welcomes more than 20% of the birds in the Lorraine region (around 6,000 individuals), making it the first wintering area in France. At dawn, it is not unusual to observe greylag geese, white-fronted geese, and, occasionally, common cranes. Three emblematic Lorraine species also station on Lake Madine's waters: the little bittern, the western-marsh harrier, and the little crake. They nest there every year alongside swans and black kites.
