The combination of deep water, islands, and freshwater
marshes make the area ideal for waterfowl, most notably the
common crane. Each spring and autumn, tens of thousands of cranes assemble here in their migration between wintering grounds to the south and breeding sites in northern Europe. Other birds recorded in the area include
white-tailed eagle,
great egret, and various
geese,
ducks,
loons (divers), and
grebes. The surrounding area is rural, a region of farmland and
forest. File:Lac-du-der-2.jpg|Lake Der-Chantecoq File:Lac-du-der-chatillon.jpg|A church at Châtillon-sur-Broué File:Lac-du-der-chatillon2.jpg|A house at Châtillon-sur-Broué ==References==
