Descrição
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 Marreco or Arrabio for example. The open water bodies are also good for terns. Moreover in Spring Pisco-de-peito-azul is easily heard and seen singing in the willows near the reedbed. Depending on the year 2-3 pairs of Alcaravão breed on the site. The bushes also host Picanço-de-dorso-ruivo and papa-amoras-cinzento as breeders. A colony of Guincho-comum is established on the islet on the easternmost water body and they are sometimes joined by some Gaivota-de-cabeça-preta.
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.
