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.
