Population densities and habitat preference granivorous birds (\kur{Passer domesticus, Passer montanus, Streptopelia decaocto}) in human settlements.
BANDHAUEROVÁ, Jaroslava
The most often mentioned causes of decrease in a number of granivoric synantropic birds are primarily changes in agriculture (liquidation of factory farming, using of pesticides, effective methods of harvest, consequences of intensification of agriculture) and changes in socioeconomical status of population (higher care of public green, decrease in numbers of small poultry farms, modernization of buildings etc.), which results in lack of food and opportunity to nest. Goal of this work is primarily evaluate an influence of the agricultural methohds on numbers of the house sparrow (Passer domesticus), tree sparrow (Passer montanus) and collared dove (Streptopelia decaocto) set a preference of habitats for selected species, addiction of their occurence on presence of small poultry farms and factory farming and compare the results with winter monitoring. Then evaluate preferences of nest habitats for house sparrow (Passer domesticus) and tree sparrow (Passer montanus). Monitoring was made in 48 chosen locations in the Czech Republic (most of those locations in South Bohemia) during the nesting period (February May) in years 2015 2016. The data evaluation was made through computer software Microsoft Excel and R v. 2.8.1 (2008). The research shows that factory farming has essentional influence on occurence of all three selected species and difference in occurence between winter and the nesting period is demonstrable. Also the difference in presence of collared dove and house sparrow is demonstrable near factory farms.

Winter Density of House Sparrow in Different types of Rural Settlements along the Czech – Austria Border
Oberpfalzerová, Michaela ; Zasadil, Petr (advisor) ; Šmejdová, Lucie (referee)
From the point of view of the Czech Republic in the last 80 years we can specify two periods, which had a significant impact on the general character and development in agriculture. The first period can be traced to the 50s of the last century, in which the concentration of agricultural production headed towards to factory farming. The second one began at the beginning of the 90s. At that time a sharp downtown of animal production occurred and the sooner concentrated production began, after the regaining by previous owners, to erode into what it is today private agriculture.
This thesis aims tocontribute to a confirmation of rejection of the hypothesis that the above described changes have a negative impact on the selected avian species. These species are represented by significantsynanthropic birds: house sparrow (which is a crucial representative in this thesis), tree sparrow and collared dove. Thirty municipalities were chosen to emphasize the differences in quantity of these species, half of them located on each side of the border with the Czech Republic and Austria. The comparison of quantities of bird populations took place in the surroundings of the cities Znojmo and Retz.In this thesis the Republic of Austria acts as a country which has not been burdened by a substantial economic development and which has applied the continuous market economy since the end of the Second World War.
In the individual squares the numbers of the representatives of the studied species and the environmental characteristics were recorded during the winter period. The significant differences in the numbers of birds at selected locations were demonstrated using a multifactor ANOVA STATISTICA 12. Moreover, the impact of selected environmental variables on the abundance of observed species was also analysed. It was found that the selected species depend on an inclusion into the individual states as well as on a classification into various biotope types. Finally, the dependence on the area of trees and bushes, the proportion of new buildings and the presence of poultry in the square were also observed. The most numerous species in the Republic of Austria was the house sparrow, the most abundant species in the Czech Republic was the collared dove. A slight increase in the occurrence of the collared dove was recorded in both states. Tree sparrow as a species occurred in relatively large numbers, but only locally. It was found that the populationsof the above mentioned species were generally more numerous in the Austrian municipalities. An interesting fact is that most of the observed individuals in the Czech Republic occurred in village built-up areas rather than in agricultural premises, as it was initially estimated.

Winter Bird Assemblages in Different types of Rural Settlements along the Czech-Polish Border
Moravec, David ; Zasadil, Petr (advisor) ; Šmejdová, Lucie (referee)
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.

A Comparison of Bird Abundance in Differet Types of Rural Settlements along the Czech-Austrian Border
Machynková, Kateřina ; Zasadil, Petr (advisor) ; Kočicová, Pavlína (referee)
In the nesting season 2015, the differences between abundances of 11 selected synanthropic species were monitored in village housing development and agricultural buildings on both sides of Czech-Austrian border in the area of Třeboň and in the Gmünd district. There were 20 municipalities chosen for this research, from whom half were in the Czech Republic and the other half in Austria. Two squares 100 x 100 m were demarcated in each village, of which one was situated mostly in the residential and the other in the agricultural area. The monitored species were house sparrow, Eurasian tree sparrow, Eurasian collared dove, European greenfinch, European serin, black redstart, European goldfinch, common linnet, common starling, white wagtail and common chaffinch. Other factors, such as poultry breeding, coverage of greenery (of herb layer, bushes and trees), the proportion of old and new housing development, etc. were monitored as well.
The number of identified species in the square and also their total abundance were significantly higher in the Czech Republic. Regarding individual species, the most noticeable difference in abundance was observed with Eurasian tree sparrow (in the Czech Republic 151 individuals, in Austria 37 individuals), followed by house sparrow (in the Czech Republic 217 individuals, in Austria 123 individuals). Significant difference was also proved with Eurasian collared dove. The most numerous detected species were in general both kinds of sparrow. Furthermore, the abundance of detected species was compared also between residential building areas in the centre of a village and the agricultural buildings on its outskirts. Significant difference was observed only with house sparrow and Eurasian collared dove, both species preferred the centre of a village, on both sides of the border. For the house sparrow he was also a statistically significant difference in the density of development in the monitored squares on the numbers in the Czech Republic. In Austria, a significant difference in percentual representation of tree and shrub layer in the monitored squares on abundance.

Numbers of selected bird species in various types of village built-up area.
Kebrle, Dominik ; Zasadil, Petr (advisor) ; Šálek, Miroslav (referee)
In Czech rupublic and similar in most of Europe, some of agricultural landscape birds abundance is declining. The biggest decline was record by House Sparrow (Passer domesticus), probably causes by changes in building technique or by lack of food opportunities. The decline in the case of Greenfinch (Carduelis chloris) and Linnet (Caduelis cannabina) is attributed to the intensification in farming. In the case of Starling (Sturnus vulgaris) is persecution by human possible cause of decline. Estimate abundance overal of eleven bird species was conducted during nestling perion in 2015 in 20 villages situated in the southwest of Central Bohemia. It was select 10 villages with working farming, in these villages was define three census site of 1 ha in different types of bulit-up area (in the centre, in the edge and in factory farm area). In 10 remaining villages was define only two census sites (in the centre and in the edge) because absence of factory farm area. House Sparrow (Passer domesticus) and Collared Dove (Streptopelia decaocto) significantly favoring village centre in villages without factory farm. Tree Sparrow (Passer montanus) significantly prefers the edges in villages with factory farming. Black Redstart (Phoenicurus ochruros) significantly favoring village centre no matter on presence of factory farming. Effect of farming on increase of birds abundance wasn´t prove. Only Collared Dove (Streptopelia decaocto) significantly avoid factory farm area. In the case of other factors (bulit-up area, area of trees and shrubs, herb layer surface, proportion of new buildings, distance from factory farm area) was prove influece of trees and shrubs area on House Sparrow (Passer domesticus), which decline abundance with increase the area. It was also prove influence of bulit-up area on Starling (Sturnus vulgaris) which decline abundance with increase the area.

House sparrow and tree sparrow in the rural settlements of Tabor region - density, distribution a their correlates
NEŠPOR, Marek
The theoretical part of my thesis was to characterize the house sparrow as a most abundant synanthropic bird species. I mentioned decline in abundance around the area and a decline in numbers in the Czech Republic and all available information on the causes of the decline. My goal in the practical field part was to determine the abundance and distribution of house and tree sparrow in the selected villages, to determine whether the abundance and distribution influence the characteristics of villages and individual buildings. The project was conducted in cooperation with the Faculty of Science of South Bohemia in Czech Budweis, ISBE AS CR, v.v.i and CSO.
