Description

Rahasane turlough is the largest surviving turlough (an intermittent lake) in Ireland. It is an important location for migrating birds, and wintering ground for the Gârliță mare. It is one of the few known breeding grounds in Ireland of the Rață fluierătoare. The Rață cârâitoare can be seen on occasion. And it is a very good place to spot accidental visitors from America, such as Rață fluierătoare americană, and from Europe, such as Chirighiță neagră.

In winter you can find Greenland Gârliță mare (nationally important numbers) and Lebădă de iarnă are regular in small numbers. There are often large numbers of Rață fluierătoare, whilst Rață mare, Rață mică, Rață lingurar, Rață moțată and Rață cu cap castaniu will also be present. There is a good chance of Rață sulițar and Rață pestriță, which are not easy to find in Galway. Winter waders include large numbers of Ploier auriu and Nagâț , with Culic mare, Fluierar cu picioare roșii, Sitar de mal and Fugaci de țărm as a supporting cast. In autumn there are often rarer waders if water levels are favourable. Birds like Fluierar mic cu picioare galbene, Fluierar de mlaștină, Bătăuș, Fugaci roșcat, Becațină mică and Prundăraș de munte have been seen.

Extra info

A turlough is a karst lake, which has no surface outlet and is surrounded on all sides by rising land. At Rahasane the drainage has been modified in that since the nineteenth century the Dunkellin river has followed an artificial channel downstream of the turlough, but part of the flow continues to go underground, via a natural sink, into the underlying limestone. Rahasane consists of two basins which are connected at times of flood but separated as the waters decline. It covers 257 ha. The site comprises marshes, seasonally flooded wet meadows, with limestone outcrops and scrub at its margins. In the summer the lake empties and the basin is grazed by cattle, horses and sheep.
