The article discusses the owls of the Pohorje Mountains (NE Slovenia). Ten species have been registered so far, 4 of them as breeders: Tawny Owl Strix aluco, Pygmy Owl Glaucidium passerinum (rediscovered in 1993), Tengmalms Owl Aegolius funereus (rediscovered in 1996) and Long-eared Owl Asio otus; 1 species, i.e. Little Owl Athene noctua, occurs here merely as a chance guest and most probably does not breed. Five species, however, have not been registered in the Pohorje Mountains in recent years, and only some of their historical data from the end of the 19th century and from the beginning of the20th century are at hand. These species are: Barn Owl Tyto alba, Eurasian Scops Owl Otus scops, Eagle Owl Bubo bubo, Ural Owl Strix uralensis (expected species) and Short-eared Owl Asio flammeus. A very interesting owls' habitat in these mountains are the environs of raised bogs (Sphagno-Piceetum association), which are shared by 3 owl species: Tawny Owl, Pygmy Owl and Tengmalm's Owl. Utterly new for Slovenia are the findings regarding the upper limit of the altitudinal distribution of the Little Owl (777 m a.) and Long-eared Owl (1,450 m a.) and the lower limit of the altitudinal distribution of the Pygmy Owl in the non-breeding season (310 m a.).
