During migration, the site acts as a migratory stopover. Many species stay there to feed and replenish their fat stores. This therefore allows many birds to return to their wintering grounds during postnuptial migration and their breeding area during prenuptial migration.
In winter, it is the body of water that makes many species happy, feeding them. We note the regular parking of Tufted Ducks (Aythya fuligula) and Pochards (Aythya ferina) or Rufous Pochards (Netta rufina).
In summer, the attractiveness of the old quarry is explained by the mosaic of environments present on the site. This diversity attracts a large number of bird species. We can mention the floodplain, which is suitable for the Red-backed Shrike (Lanius collurio) or the Yellowhammer (Emberiza citrinella), or the reed bed in which nests the Turdoid Warbler (Acrocephalus arundinaceus) or the Reed Bunting (Emberiza schoeniclus).
