Abstrakt		During 1992-1999, the author registered only 2 owl species in the Lower Savinja valley (Central Slovenia), i.e. Tawny Owl Strix aluco and Long-eared Owl Asio otus. The first is here a rare species, while the latter is rather common. Tawny Owl can be found primarily on the fringes of the valley with predominating woodlands. In the 9.25 km2 large area with its characteristic valley pattern (woodland and shrubs - 4%, orchards and gardens - 3%, tilled fields, meadows - 40%, hop fields - 40%, settlements - 7%, other: roads, ditches, embankments - 6%) the Long-eared Owl was registered, in 1999, to the density degree of 1.6 pair/10 km2. Dolinar (1951) who carried out, in this area, a general bird census more than half a century ago stated utterly different proportions between owls: Tawny Owl and Little Owl were common, while Long-eared Owl did not even get a mention. Such different species structure was most certainly influenced by intensive Farming, particularly hop growing.
Izvleček		V spodnji Savinjski dolini (osrednja Slovenija) je avtor med letoma 1992 in 1999 registriral samo dve sovji vrsti, in sicer lesno sovo Strix aluco in malo uharico Asio otus. Lesna sova je v dolini redka vrsta, mala uharica pa običajna. Prva je precej pogostejša na obrobju doline, to je na okoliških hribih, kjer prevladuje gozd. Na površini 9,25 km2 z značilnim vzorcem doline (gozd in grmovje - 4%, sadovnjaki in vrtovi - 3%, orane njive, travniki - 40%, hmeljišča 40%, naselja - 7%, drugo: ceste, jarki, brežine 6%) je bila mala uharica v letu 1999 ugotovljena v gostoti 1,6 para/10 km2. Dolinar (1951), ki je tukaj ptice popisoval pred dobrimi petdesetimi leti, navaja povsem drugačno razmerje med sovami: lesna sova in čuk sta pogosti vrsti, medtem ko male uharice sploh ne omenja. Na drugačno vrstno sestavo sov je prav gotovo vplivala intenzifikacija kmetijstva, predvsem gojenje hmelja v dolini.
