  • Sove spodnje Savinjske doline = Owls of the lower Savinja valley
    Vogrin, Milan
    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 hopgrowing.
