Abstract: Two subfossil sites of the Eagle Owl, near the village of Shirokovo (Early-Late Holocene) and Nisovo (Late Holocene) in the Rousse region, have been examined. At least 105 species of birds and mammals have been recorded, 90 of them represented in the local vertebrate fauna (23,02 % of its species composition). There are 67 species of birds of 15 orders and at least 38 species of mammals of 6 orders. High habitat diversity (aquatic, wood, field, rock and synantropic) can be assumed from the ecological complexes of the established taxa. The finds of 9 bird species represent the first records of fossil/ subfossil fauna in Bulgaria while the finds of 11 bird species — the second records in the country. The finds of 6 bird and 10 mammal extinct, threatened or rare species are important and mark their former distribution in the country.
