This Diploma thesis is focused on topic of bird migration phenology in area Slovenské stredohorie during period 2015-2020. The thesis puts these data to direct context with climate change during bird migration season. Based on the SHMÚ agrometeorological data from stations Banská Štiavnica, Bzovík, Sliač and Žiar nad Hronom was prepared table a graphic overview about precipitation, air temperature and sunlight. On the same base were prepared overviews for bird migration phenology of bird species Hirundo rustica, Delichon urbica, Ciconia ciconia, Sturnus vulgaris, Alauda arvensis, Cuculus canorus from area of central Slovakia. Obtained data were evaluated and compared, according to these results was specified relationship between climate conditions and bird phenology of arrivals, flocks making and departure dates. The thesis refers and confirms interactions of both features, when favourable climatic conditions affect earlier arrivals and later departures and on the other side cold and rainy weather and low sunlight later arrivals and faster departures. The thesis confirms, that bird migration is suitable tools for assessment of climate change impact, because bird phenology is its direct bioindicator.
