Quantitative results of investigations of breeding bird communities and non-breeding bird communities revealed potential abilities to increase in number of species and abundance of birds in rural environment due to implementation of poplar plantations. Field research was carried out in two poplar plots and adjacent cultivated fields. Breeding bird communities consisted of 32 and 30 species inhabiting the plots, and density index for these communities was 77.6 and 88.4 pairs/10 hectares respectively. On these plots in the period from 24 October to 24 February there were 17 and 14 species registered during four censuses. Mean value of density index of these communities was 58.7 and 53.6 individuals/10 hectares. Breeding bird communities and non-breeding bird communities recorded in cultivated fields were very low in number of species and with very low density.
