Methods used to determination of quantity of house sparrow (Passer domesticus) and similar synanthropic birds

Population of many synanthropic species of birds is decreasing in a lot of European countries including the Czech Republic. This decrease is apparent especially in urban areas. Cause of this decrease has not been entirely specified. The aim of this thesis is to evaluate possible factors affecting bird population. One of the influencing factors could be the size of observed territory. During nesting season of 2014, research monitoring 11 bird species was carried out in 10 villages of Kladno county. The species of birds are House Sparrow (Passer domesticus), Eurasian Tree Sparrow (Passer montanus), Eurasian Collared Dove (Streptopelia decaocto), European Greenfinch (Carduelis chloris), European Serin (Serinus serinus), Black Redstart (Phoenicurus ochruros), European Goldfinch (Carduelis carduelis), Common Linnet (Carduelis cannabina), White Wagtail (Motacilla alba), Common Chaffinch (Fringilla coelebs) and Common Starling (Sturnus vulgaris). Birds were counted on several counting plots in different types of habitat. Aim was to inspect effect of habitat on abundance of bird species. The results show, that type of habitat had effect on most of the bird species. This outcome corresponds with some of the former studies
