Abstract

In this paper, the authors show the results of the midwinter waterbird census performed on the basins Vâlcele, Budeasa, Bascov, Piteşti and Goleşti from the ROSPA 0062 The Basins of the Argeş River. 45 bird species belonging to 12 orders were observed. Passeriformes (15 species) and Anseriformes (13 species) were the richest orders by the number of species. Unlike other years (when the Goleşti basin was in the first position), the biggest numbers of individuals was noted on Piteşti Basin. The local conditions of depth, surface, and speed of water for every basin determined the size of the unfrozen surface of water necessary for the waterbirds. Their numbers were determined by the anthropogenic pressure, food supply, places for rest, too. The highest Jaccard similarity was between Vâlcele and Budeasa ornithocoenoses and the highest Bray-Curtis similarity was between Piteşti and Budeasa ornitho-coenoses. Anas platyrhynchos and Fulica atra were the eudominant species. The Anseriformes and Charadriiformes orders were overdominant and, into the Anseriformes order, Anas platyrhynchos and Aythya ferina were the overdominant species. Gavia arctica, Phalacrocorax pygmeus, Egretta alba, Cygnus cygnus, Mergus albellus and Alcedo atthis are in the Annex I of the Birds Directive.
