Description
The river Conie emerges from the Beauce phreatic table and thus the site's interest varies from year to year depending on water level. Surrounding fields are excellent for Triel and the common suite of cropland species include Tornsanger, Kirkeugle and Tornskate. If the river has water, waders can occur both in the river bed itself and in water patches in surrounding fields. Herons (incl. Purpurhegre), Rørsanger and Gresshoppesanger breed if water level is sufficient. Fiskeørn, Svartstork and other migrants may occur, mostly in spring migration. Boltit is a rare but regular (yearly) passage migrant in large fields surrounding the valley. In winter, Jordugle may roost in wastelands around and large parties of Vipe and Heilo gather especially under cold weather.

Access
The easiest way to explore the area is to drive or bike the local roads that run along the valley. From Châteaudun, a good start is to reach Moléans, then move eastwards to Conie-Molitard, Vallière, Nottonville, Varize, Péronville, Villeneuve sur Conie and leave the area through Patay. Make stops wherever the habitat looks good to you. For Boltit, the area between Péronville, Bazoches en Dunoy and Cormainville is probably the best. Triel) can be found anywhere in this area. Dverglerke used to breed here but no breeder has been confirmed since the 2000's (the species may still occur during migrations).
