During ornitological investigation of the gravel pits carried out in western Slovakia in the years 1990-1997 there were find 117 bird species in 14 localities. This number represents 33 % of all species found in Slovkia up to now. 61 species of them were bound to water biotopes. From among the found species fifty species are risk bird species. The characteristis species of gravel pits in the investigated regions are eudominant and dominant, resp. euconstant nidificants: Podiceps cristatus, Cygnus olor, Anser anser, Anas platyrhynchos, Aythya ferina, A. fuligula, Larus ridibundus, Fulica atra, Riparia riparia, Motacilla alba and Acrocephalus arundinaceus. In this kind of biotopes species diversity is dependent mainly on the water and shore vegetation and terrain dissection, i. e. existence and number of islands in the locality. The investigated localities are important landscape segments substituting the liquidated marsh biotopes
