Breeding population of the Eurasian Eagle-owl (Bubo bubo) is localized mainly in marginal parts and foothills of Tribeč Mts., Považský Inovec Mts. and Strážovské vrchy Mts. In 2013–2017 we checked 72 sites (in study area 1440 km2) and found 30 breeding pairs (i.e. density 2.1 pairs/100 km2). Altogether we recorded 81 breeding attempts, of them 57 successful and 118 chicks (11 nests with 1 chick, 32 with 2, 13 with 3 a 1 with 4 chicks). We analysed distribution and density of nests according to habitats (abandoned stone quarries, active stone quarries, rocky slopes, tree nests in forest, buildings). The abandoned stone pits was the best habitat (in the sense of chicks number; 45 successful nests of 59 nests = 76.3%), when 91 chicks fledged (77.1% of all fledged chicks). Based on this study we can conclude that the population was stable within the study period.
