The results of the researches performed between February 2013 and January 2014 on the birds of the Goleşti reservoir from ROSPA0062 Lacurile de acumulare de pe Argeş are shown in this paper. The 91 observed species belong to 13 orders, Passeriformes being the richest (with 31 species). 53 species are totally or partially dependent on wetlands. The monthly variation of the number of species and individuals reflects both natural and artificial processes. A few species (Anas platyrhynchos, Aythya fuligula, Aythya ferina, Larus ridibundus) were noticeable because of their frequency and abundance and this is why they dictated the general dynamics of the local avifauna. As a result, the Anseriformes and Charadriiformes are the overdominant orders at general level. 21 species are included in the Annex I of the Birds Directive. The qualitative and quantitative alterations observed over time do not show necessarily the climatic changes, because the conditions of the basin did not remain constant.
