The importance of rural parks for the occurrence of the Rook Corvus frugilegus in the eastern part of the Lublin region (E Poland) – ecological and social factors

Kitowski I.: The importance of rural parks for the occurrence of the Rook Corvus frugilegus in the eastern part of the Lublin region (E Poland) - ecological and social factors. Ekologia (Bratislava), Vol. 32, No. 3, p. 283-298, 2013. This study deals with the population size and the distribution of breeding colonies of the rook in rural parks in the eastern part of the Lublin region (Eastern Poland). Large parks with a large number of tree species were appropriate sites for larger rookeries. Small, degraded parks, with few species of trees, were used by smaller rookeries, which showed tendencies to disappear more quickly. Small colonies were irrevocably abandoned if disturbed by man, whereas large ones had a very high reoccupation potential, even after a few years. Unfortunately, ownership changes concerning rural parks in Eastern Poland may endanger the rookeries located there.
