Fauna   An area so rich with different environments and vegetal species, allows many animals to grow and spread. The piscifauna, supported by the good quality of the water, includes the pike, the common whitefish, the perch, the tench. The amphibians are numerous, such as the edible frog, the tree frog, the common toad and the European green toad; amongst the reptiles we find the grass snake, the water-snake, the Hermann's tortoise and the Aesculapian snake. With the disappearance of the otter, amongst the mammals we find the nutria, the fox, the badger, the wild boar, the pine marten, the European polecat and the wildcat, which is more and more rare. The point of greatest interest and attraction for the visitors is the avifauna, which is quite varied thanks to the presence of different environments such as the wood, the marsh, the swampy meadows, the cultivated lands and the lake. On the banks and on the surface of the water it is possibile to watch many species of waterfowl, such as the coot, the tufted duck, the pochard, the mallard, the whistling duck, the gadwall and the common teal. Amongst the other species we find the great crested grebe, symbol of the Reserve, the herons, the little bittern, the little egret, the water rail, the squacco heron, the black-necked grebe and thousands of starlings that spend the winter nights on the willows of the banks and in the reed-beds. With regard to the birds of prey, we find the lanner falcon, the black kite, the sparrow-hawk, the common kestrel, the marsh harrier and the peregrine falcon. The woods are inhabited by nocturnal predators like the barn owl, the tawny owl, the long-eared owl, the little owl and the scops owl. In the thick woods we find woodpeckers, Eurasian jay-birds, chaffinches, blue tits, hoopoes and winter wrens.
