Between the banks of the river and those of the lakes, the gray heron and the Martin fisherman each have their hunting stations while the Black Milan occupies the role of the cleaner by recovering the corpses of fish and amphibians. The water bodies also host several species of remarkable birds for the region, in staging areas such as the Knights Cul-blanc and Guignette, the Northern Shoveler or Garganey and exceptionally the Osprey.
