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 (Ευρασιατικός) Ήταυρος and (Ευρωπαϊκός) Μικροτσικνιάς, 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 (Ευρασιατικό) Φερεντίνι and (Ευρασιατική) Χουλιαρόπαπια, with (Ευρωπαϊκό) Σφυριχτάρι and Ψαλίδα (του Βορά) becoming rarer in recent years. (Ευρωπαϊκή) Σαρσέλα can be observed from spring to autumn, and Χηνοπρίστης is present year-round. The pond also attracts some escapees, with records of Mandarin Duck, Wood Duck, Netta peposaca, and Anas bahamensis.

The reedbeds are dominated by Αρκοπετείναρο, Καλαμοποταμίδα, and Σταχτοτσικνιάς. Among them, other species like (Ευρωπαϊκή) Αλκυόνη, (Ευρωπαϊκή) Νεροκοτσέλα, and (Κοκκινόλαιμο) Νανοβουτηχτάρι, which are present year-round, and Τσιχλοποταμίδα, which breeds here, may be encountered. During migration, Υφάντρα, Σχοινοποταμίδα, (Κοινός) Νυχτοκόρακας, and Πορφυροτσικνιάς can be seen. (Ευρωπαϊκός) Μικροτσικνιάς breeds here in spring and summer, while (Ευρασιατικός) Ήταυρος visits only in winter, accompanied by Καλαμόκιρκος and Αργυροτσικνιάς.

In the marginal areas, waders such as Ποταμοσφυριχτής and Μαυρότρυγγας were more common in the past. Today, Δασότρυγγας, (Κοινό) Μπεκατσίνι, and (Ευρωπαϊκή) Καλημάνα 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 Καστανολαίμης, Φασσοπερίστερο, (Κοινός) Φασιανός, (Κοινό) Αηδόνι, Αετομάχος, Ορφεοστριτσίδα, and Λιβαδοκελάδα. The likelihood of spotting a rarer pipit or breeding bird here may be greater than within Rouelbeau itself. The notable rarities recorded, including (Ξανθός) Κρυπτοτσικνιάς, Δρεπανοσκαλίδρα, and Καλαμοκανάς, 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!
