Abstract:
In 2017-2019, a nesting survey of the Rook "Corvus frugilegus" was carried out in the Świętokrzyskie Mountains (14,400 km2). The majority of controls were con?ducted in April. Overall, 15,622 nests were recorded at 166 sites. Mean density was 108.5 nests/100 km2 and 1.2 colonies/100 km2. Rooks most often nested in large colo?nies (101 to 500 nests), comprising 61.5% of all nests and 27.1% of all colonies. Most colonies were located on deciduous trees (77.1%), in contrast to the low number on coniferous trees (4.8%). ; The largest colonies were located in parks. This number was significantly higher than the number of nests in tree lanes, wooded land and single trees. Only one colony was located outside human settlements. There was a positive correlation between the number of inhabitants and the number of rooks breeding in the respective town or in its close vicinity.
