Abstract
In this paper, the authors show the situation concerning the occurrence of the birds species observed during the International Waterbirds Census in 2012 on the Vâlcele, Budeasa, Bascov, Piteşti and Goleşti basins from the Important Bird Area “Lacurile de Acumulare de pe Argeş”. The identified species belong to 10 orders (Podicipediformes, Pelecaniformes, Ciconiiformes, Anseriformes, Falconiformes, Gruiformes, Charadriiformes, Columbiformes, Piciformes and Passeriformes). Anseriformes was the best represented order regarding the numbers (14517 individuals) and Passeriformes was the best represented order regarding the number of species (19 species). Anas platyrhynchos recorded 8404 individuals (35.47% of the registered total – 23696 individuals). From the ecological point of view, Anas platyrhynchos, Aythya ferina and Larus ridibundus (6.52%) were eudominant species, Anas crecca, Fulica atra and Larus canus (6.52%) were dominant species, Anser albifrons and Larus cachinnans (4.34%) were subdominant species and Phalacrocorax carbo and Aythya fuligula (4.34%) were recedent species. The subrecedent species were the most numerous (36 species: Podiceps nigricollis, Phalacrocorax pygmaeus, Tadorna tadorna, Mergus albelus, Picus viridis, Troglodytes troglodytes, etc., 78.26%). About the conservation based on the Birds Directive, 5 species (10.86% - Phalacrocorax carbo, Phalacrocorax pygmaeus, Egretta alba, Circus cyaneus and Dendrocopos syriacus) belong to Annex I.
