On the basis of systematic watching of birds in Kočevsko forestry region and their survey in
fir-beech virgin forest remains, the impacts of various ecological (forest community, altitude,
gradient, relief, fructification of some tree and shrub species, etc.) and other factors (forestry
management classes, forest development phase, growing stock, prescribed increment, hunting
management) on the distribution of selected bird species in Kočevsko forests were studied.
The selected species were: Ural Owl (Strix uralensis), Tengmalm's Owl (Aegolius funereus),
Little Owl (Glaucidium passerinum), Hazel Grouse (Bonasa bonasia), Black Woodpecker
(Dryocopus martius), White-backed Woodpecker (Dendrocopos leucotos), Three-toed
Woodpecker (Picoides tridactylus) and Red-breasted Flycatcher (Ficedula parva). The
majority of observations were made in April and May, mostly on northern expositions and at
higher altitudes. The Three-toed Woodpecker frequents dead standing coniferous trees in the
stoniest high altitude areas. Owl niches overlap each other to a much greater extent than those
of woodpeckers. The Ural Owl inhabits the more productive natural sites, while other owl
species can be found predominantly in places with no larger species. Among the studied
species, Ural Owl has the widest ecological niche, Little Owl the narrowest. Lower growing
stock and greater variegation of the stands can be found in Hazel Grouse's habitat. As far as
forest development trends are concerned, they appear to be favourable, in the short run, for
the majority of bird species under consideration. All the studied birds are on the list of
protected species within Natura 2000 network, and their living conditions should under no
circumstances worsen in their habitats. The thesis can serve as an expedient for zonation and
management plans concerning of the above studied bird species.
