Observer les oiseaux du lac de Chalain (Jura)

Lake Chalain is located near the village of Fontenu, in the department of Jura, 30 kilometres from Lons-le-Saunier and 15 kilometres from Champagnole. It is the largest lake (232 hectares) of the Jura. It was formed by glaciers and men have walked its shores for centuries : the signs of the first people living on this lakeside go back to 3,800 years BC.  
The plateau and the slopes in the north of the lake are covered with beech forest, and the west shores are bordered with a riparian forest and meadows.
It is very attracting for wintering birds, mainly diving ducks (including the Ferruginous Duck, which is regular), grebes, divers … Flocks of dabbling ducks can we be watched during the migration periods, and the Common Merganser is more and more regular. In spring, the cliffs and forests near the lake can be interesting (several species of raptors, Bonelli’s Warbler, Raven, …).
Eric Wolff, who organizes guided tours in the Jura, presents us this lake.
