Abstract: 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 chick
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.
