Description

Rouelbeau can be conveniently visited after a trip to the nearby Marais de Sionnet (also described on Birdingplaces). Both sites are results of the Seymaz River renaturation projects carried out in the 2000s. Unlike the Marais de Sionnet, Rouelbeau lacks the floodplains suitable for waders. Among the 175 species recorded here, regular visitors and residents of the reedbeds include Rørdrum and Dvergrørdrum, along with other notable species.

Once a marsh, Rouelbeau is now a 410-meter-long but only a few dozen meters wide pond surrounded by reeds. It can be observed from one of its narrow ends. While the pond and reedbeds are interesting year-round, the surrounding fields are especially rich in surprises during migration periods.

Focusing on the pond area, winter offers good chances of seeing Rødhodeand and Skjeand, with Brunnakke and Stjertand becoming rarer in recent years. Knekkand can be observed from spring to autumn, and Laksand is present year-round. The pond also attracts some escapees, with records of Mandarinand, Brudeand, Netta peposaca, and Anas bahamensis.

The reedbeds are dominated by Sivhøne, Rørsanger, and Gråhegre. Among them, other species like Isfugl, Vannrikse, and Dvergdykker, which are present year-round, and Trostesanger, which breeds here, may be encountered. During migration, Pungmeis, Sivsanger, Natthegre, and Purpurhegre can be seen. Dvergrørdrum breeds here in spring and summer, while Rørdrum visits only in winter, accompanied by Sivhauk and Egretthegre.

In the marginal areas, waders such as Dverglo and Sotsnipe were more common in the past. Today, Skogsnipe, Enkeltbekkasin, and Vipe are occasional guests during migration, with the latter two sometimes staying into the winter months.

From April to May, the surrounding fields and hedges are worth exploring for Buskskvett, Skogdue, Fasan, Sørnattergal, Tornskate, Spottesanger, and Heipiplerke. The likelihood of spotting a rarer pipit or breeding bird here may be greater than within Rouelbeau itself. The notable rarities recorded, including Topphegre, Tundrasnipe, and Stylteløper, date back to the early 2000s.

Access

Rouelbeau can be reached on foot from the Marais de Sionnet (1) in about 15 minutes. During migration, it’s worth checking the surrounding fields and hedges on the way for pipits, buntings, and various warblers. If you want to start at Rouelbeau itself, the nearest bus stops are Carre d’Amont or Meinier, Pralys. For those arriving by car, parking is available at the nearby sports center (Press P on the map for directions). However, the best way to explore the area is by bike.

Unfortunately, the site itself can only be observed from one location (2), with most waterbirds usually gathering at the far end (3). Bringing a scope and a bit of patience is highly recommended!
