The Foraine d’Authie site is made up of a series of bodies of water resulting from the exploitation of old pebble cords. This former quarry, in the process of being recolonized by the natural environment, has been the subject of recent ornithological developments (islets, mudflats, etc.), associated with grazing of all the meadows. These allow a large public to enjoy the discovery of the site and admire the Spoonbills, Cormorants, Black-headed Gulls, Avocets, Mergansers, etc., which occupy this natural space.
