Beskrivning
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, Smådopping, vattenrall and rörhöna become less common and harder to spot due to dense vegetation, the reedbeds and hedgerows have hosted sydnäktergal, rödstjärt, and häcksparv, with appearances of pungmes, blåhake, and gräshoppsångare during migration. The mature trees in the area provide habitat for skogsduva, mindre hackspett, mellanspett, gök, and sommargylling. The sparvhök also hunts here, and visits from kattuggla and even hornuggla, 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.
