The Perruchet pond is one of the most interesting in the department. The avifauna is of great wealth, whatever the period of the year.

It  is the only site of Eure-et-Loir colonized by the black-necked grebe at  the time of nesting and for the reproduction of the duck eel.

During  the migrations, the pond is a renowned stage: the Souchet duck, the  Fuligule Milouin and other rare species, such as the Nette Rousse or the  Goose Goose, for the family of ducks, as well as the Knight Guignette,  the Curlew or Great Egret for the family of waders, can stay there for several days.

Raptors, such as the majestic Osprey, are also regularly observed hosts.
