SPATIO-TEMPORAL DYNAMICS OF WINTERING POPULATION OF ROOK (CORVUS FRUGILEGUS) IN ZHITOMIR

We studied the density and spatial distribution of rooks in Zhitomir during the winter season. The researches were performed from November to February in 2009–2011. We tested the effect of year, month number, biotope identity, and snow cover density on density of rooks. We came with the conclusion that year, month number, and snow cover had no significant effect on the density of Rooks. We also proved that the changes in biotopes had led to significant fluctuations in birds’ density.
