 abstract={Studies carried out in the vicinity of Rogów in central Poland showed a 47% rise in the population density of the Common Buzzard, inasmuch as the average number of breeding pairs in the study area of 105 km2 increased from 18.2 in the years 1982–1991 to 26.7 in the years 2001–2003. Furthermore, an upward trend was observed for each separately investigated forest complex. Possible mechanisms underpinning this increase in density are discussed.},
