Abstract:

In this paper, the authors display the results of the ecologic research on the bird fauna in the area of the reservoirs on the middle valley of Arges river during the prevernal season. Thus, the spring season was the richest regarding the number of species (186 species were identified belonging to 17 orders, 45 families and 107 genera); 77 species depend on wetlands. We perform an analysis of the avifauna according to ecological indices ((IR, constancy, dominancy, the Dzuba index of ecological significance, etc.). The Anseriformes and Passeriformes orders were overdominant in the researched season. The very large number of accidental species in the spring season (97), alongside the large number of subrecedent species emphasize the existence of a very large fluctuation of the bird species (Anseriformes, Charadriiformes, Passeriformes) in the studied area, especially on Golesti lake, these lakes being located on the Ruc─âr-Bran Corridor migration route. 39 species are listed on Annex I of the Birds Directive.

Keywords:
