Summary Vaida Kemežaitė: Changes of Ornithofauna in Intensively, Extensively and Destructively Used Agrocenosis. The Master’s Thesis of Ecology/ scientific adviser doc. dr. S. Sinkevičius. Vilnius: Vilnius University, Faculty of Natural Sciences, Centre of Ecology and Environmental Science, 2010 – 50 p. This Master’s Thesis analyzes the changes of ornithofauna in agrocenosis, where successive changes of different degree occur. The aim of thesis is to identify the presumable changes of ornithofauna in the territories of Lithuania landscape, where different anthropogenic effect exists, i.e. intensive, extensive and destructive. In the thesis, the territory of intensive use of land in Vilkaviskis region and the territory of extensive and destructive use of land in Vilnius region are described. The research on breeding birds’ specific consists and superfluity is carried out on the backgrounds of point counts method. Making comparisons of 2 – 6 years researches some typical species of agrocenosis were identified. These species survive in the territories where extensive and destructive impact occurs, i.e. Common Starling (Sturnus vulgaris), Skylark (Alauda arvensis), Whinchat (Saxicola rubetra), Partridge (Perdix perdix) and Yellowhammer (Emberiza citrinella). In the territories, where extensive use of land exists there are more scrubland species, such as Tree Sparrow (Passer montanus), Chaffinch (Fringilla coelebs), Tree Pipit (Anthus trivialis). In all explored territories, the most frequent are Common Starling (Sturnus vulgaris), Skylark (Alauda arvensis), Whinchat (Saxicola rubetra), Wood Pigeon (Columba palumbus), and Barn Swallow (Hirundo rustica). In the territory of intensive use of land, there is the largest quantity of registered persons (i.e. 62) in comparison with the territories of extensive and destructive use of land. The widest specific variety (i.e. 19) is registered in the territory of extensive use of land.
