In the last few years there has been a significant decrease in the of number of wild birds across the Europe. It is mostly concerns synantropic species and species related to agricultural landscapes. The main cause of this decrease could be the changes in agriculture and also changes in the character of village surroundings and therefore the connection to a decrease of livestock.
In this thesis a comparison of the differences in the bird community in winter months has been made, focusing on a sparrow in the Czech-Polish borderlands. There have been found differences between the agriculture development and development of rural settlements in each of these countries especially in the second part of the 20th.century. At the end of my thesis there are the comparison results of my thesis and the research, that was carried out in the summer months of 2014.
The main research was done between December 2015 and January 2016 along the CzechPolish border. 16 villages were chosen and in each village there were 2 research areas the the dimensions of 100 x 100 meters. The total study consists of 64 research areas in different types of environments. The data collection was done twice in each area.
The results show that in the Czech republic there occurred more birds and also birds species. It has been demonstrated, that poultry farming has a major impact on sparrow numbers. Out of the six surveyed habitats the one with the most birds was found to be found in the middle of a village with a factory farm and the most bird species were found on the outskirts.
