Description

A path encircles this small nature reserve, though most views are limited to hedges and the reedbed edges. The former marsh area is gradually overgrowing and becoming bushy, while the wetland itself is undergoing eutrophication. This and the presence of the nearby hotspot Marais de Sionnet are the reasons why the Marais du Château does not receive much ornithological attention. However, over 120 recorded species include some noteworthy recent sightings.

As waterbirds such as different duck species, Kis vöcsök, Guvat and Vízityúk become less common and harder to spot due to dense vegetation, the reedbeds and hedgerows have hosted Fülemüle, Kerti rozsdafarkú, and Sövénysármány, with appearances of Függőcinege, Kékbegy, and Réti tücsökmadár during migration. The mature trees in the area provide habitat for Kék galamb, Kis fakopáncs, közép fakopáncs, Kakukk, and Sárgarigó. The Karvaly also hunts here, and visits from Macskabagoly and even Erdei fülesbagoly, which nest sometimes in the region, are not excluded.

The higher elevation of the Marais offers a quieter alternative to Marais de Sionnet, along with its own intriguing birdlife. Pro Natura plans to further develop the site, with hopes of restoring the wetland’s appeal to waterbirds.
