Abstract		In the year 2000, a census of the Ural Owl Strix uralensis was carried out in selected areas of the Javorniki Mountains. The census was performed three times between April and the end of June by means of the playback method. The established density of 5,1 pairs/10 km2 corresponds to the highest Ural Owl densiry in Slovenia. During the census, altitudinal belrs from 600 to 1100 meters above sea level were surveyed. It was established that the highest Ural Owl density was in the altitudinal belt stretching from 900 to 990 meters above sea leve(, which fully corresponds to the results obtained by previous researches.
