Abstract
Along with the changes in the management of human, which took place from the mid-20th century, bird populations changed the balances. The aim of my thesis is to determine the differences in the abundance and distribution of selected species of synanthropic birds. These concern of the following species: House sparrow (Passer domesticus), Tree sparrow (Passer montanus), Collared dove (Sreptopelia decaocto), Common linnet (Carduelis cannabina), White wagtail (Motacilla alba), Common chaffinch (Fringilla coelebs), Black redstart (Phoenicurus ochruros), European goldfinch (Carduelis carduelis), Common starling (Sturnus vulgaris), European greenfinch (Carduelis chloris) and European serin (Serinus serinus). Using the simplified method of mapping (Bibby et al. 1992), the bird census took place in spring 2015 in 20 villages on the Czech-Austrian border. Counting squares were set in each village for different types of environment: the center of the village, edge of village and agricultural area including farm building with livestock.
The results confirm the dependence of house sparrow to agricultural areas with breeding livestock in the Czech Republic. Abundance, density and frequency was evaluate for each species separately. Effect of biotope and state were significant effects only for House sparrow population. Factors of poultry and built up area were significant for White wagtail bird. Effect of state was significant for bird species Collared dove. There were no effects for Tree sparrows populations.
