Description
The area is really good throughout spring particularly when some areas have been flooded during winter. In fact high water conditions combined with the grassy area create a very good stopover site for čírka modrá or ostralka štíhlá for example. The open water bodies are also good for terns. Moreover in Spring slavík modráček is easily heard and seen singing in the willows near the reedbed. Depending on the year 2-3 pairs of Dytík úhorní breed on the site. The bushes also host ťuhýk obecný and pěnice pokřovní as breeders. A colony of racek chechtavý is established on the islet on the easternmost water body and they are sometimes joined by some racek černohlavý.
Of course it can be useful to check the water bodies in winter for ducks but there are often fishermen near the lakes so ducks are rarely as numerous as on other water bodies in the region.
