    To assess Stock Dove breeding abundance and habitat associations, we mapped calling males in the western part of the Cerová vrchovina Mts. (61 km2 ) during 2016. Oak, Hornbeam and Black Locust dominated in the studied forests (36.6 km2 ) while Beech stands aged >60 yrs covered only 3.7% of the forests. Calling males were recorded in 50–125 yrs-old forest stands. When considering calling male records as surrogates of breeding pairs, breeding density was 1.88 pairs/100 ha of the total forest area. The local density varied between 0.05 and 2.17 pairs/ha. The local density of calling males was positively associated with stand age and the proportion of Beech trees in the forest stand. These predictors accounted for 50.0% of variance in Stock Dove density with the proportion of Beech trees explaining ca. twice as much variance as did stand age. A breeding population for the study area in 2016 was estimated to be 69 pairs.
