This diploma thesis summarizes and analyses phenological manifests of migrating birdlife with focused on climate changes, which have influence on this manifests. For research areas were chosen geomorphological district of Krupinská planina and Štiavnické vrchy and research period were from 2014 to 2019. Based on meteorological information from stations Bzovík and Banská Štiavnica and based on phenological information from central Slovakia were created records about climatological characteristics - air temperature, humidity, solar energy and about bird phenology in studied area during 5 years period. Birdlife of these spieces was studied Hirundo rustica, Delichon urbica, Ciconia ciconia, Sturnus vulgaris, Alauda arvensis, Cuculus canorus. Than both these data records were compared and results were identified with focus on influence of climate changes and birds migration behaviour. It was found out, that favourable conditions influence earlier bird arrival and rainy and lightly sunny weather influence earlier birds departure.
