| Résumé : | The Barn Owl Tyto alba was found as rock-nester for the first time in Bulgaria. The pair bred successfully in a crevice with northern exposure, which situated 5 m from a plucking place and 3 m from the upper edge of the rock with a prominent shelter. The Barn Owl nest was on around 12 m distant from the traditional Eagle Owl Bubo bubo nest in the same rocks. The coexistence of the two owl species did not increase the Eagle Owl's predation on Barn Owls. |
