Descripción
The Barrage de Verbois offers an excellent view of the river Rhône, which flows southwards from Lake Geneva. It serves as an orientation for many birds migrating through the ‘bottleneck’ between the Jura and the Alps. The reservoir is also a place where waders and terns can rest and find food. Among the 240 species recorded here are numerous rarities, especially from those groups.
The 340 metre long and 34 metre high dam, which serves a hydroelectric power station, is an impressive structure. The lake can be seen both at its eastern end, facing Aire-la-Ville, and at its western end, from which you can reach the vineyards near Russin. The eastern platform is the best place to start. There are breeding platforms for Charrán Común on the lake, but at some distance, so a scope is necessary. The birds rest on perches set up in the lake. It is also worth checking the washed-up island of plant debris and rubbish in the centre of the dam for waders. At the western end there is a small reedbed where Avetoro Común (in the winter) and Avetorillo común have already been spotted.
For a few years now, there have been a few Cormorán Pigmeo dwelling on the lake, adding a regular ornithological attraction to the colony of Charrán Común. Fumarel Cariblanco, Fumarel Común, and even Charrán Patinegro are sighted almost regularly at the right times of year. Cigüeñuela común, Avoceta Común, Pagaza Piconegra, Pato Havelda, Archibebe Oscuro, Ostrero Euroasiático, and more common waders such as Correlimos Común have also been reported more than once. Breeding birds around the lake include Tarro Blanco, Martín Pescador Común, Paloma Zurita, Pico Menor, and Torcecuello Euroasiático.
While waterfowl such as Cuchara Común, Cerceta Común, and, with luck, Porrón Bastardo and Colimbo Chico are present in winter, spring is the best time for a scan of the lake. The terns arrive from May onwards. The Ruiseñor Común then sings in the bushes on the shore and the song of the Oropéndola Europea can be heard from the nearby Teppes de Verbois. During the autumn migration, the site is particularly interesting for waders.
