Rezumat: This paper presents the breeding avifauna of the Breite plateau in comparison with the breeding avifauna of the surrounding forest, accounting for alpha, beta and gamma diversity. The bird species are considered from the perspective of their feeding habits, nest site selection and protective status. 57 breeding bird species were identified, from which 32 species on the plateau, 46 species in the surrounding forest and 21 species were found breeding in both habitats. Due to its small area and elongated shape, the plateau has a large ecotone and the surrounding forest has a great influence on its avifauna. 21 of the bird species that were found in both habitats are forest species. Only 11 species are breeding exclusively on the plateau and all are open habitat species. 25 species nest exclusively in the forest, indicating again the dominance of forest species over the total species number. The bird species from the two studied habitats belong to five trophic categories, the insectivores being dominant in both cases. The several century-old oaks from the plateau represent important feeding habitats for insectivore birds, especially for the bark-feeders. The cavity nesters are the best represented among the species breeding on the plateau. The open nests builders are best represented among the forest-nesting birds. Those that nest on soil are less represented in both habitats. Out of the 32 species that are breeding on the plateau, six are protected according to the Birds Directive (79/409 EEC), Annex I, emphasizing the conservation importance of the Breite reserve. |
