Abstract		In 1998, 18 human settlements in the area of 93 km2 were searched for the Eurasian Scops Owl Otus scops territories (calling males) on central Pelješac Peninsula (S Dalmatia, Croatia). The playback method was used. In all settlements, 90 singing males were counted, which indicates that the total urban breeding population of Eurasian Scops Owl on Pelješac Peninsula was around 345 pairs in 1998. According to the author's opinion, the larger part of the Eurasian Scops Owl population breeds in the area within settlements. With a crude density of 10 - 15 pairs/10km2 and by considering the population dynamics recorded in the village of Kuna, the total population on Pelješac peninsula was estimated at 230 to 575 pairs. Further ecological densities for several clumps of urban populations are presented. Ecological densities have found to be very variable (0.6 - 9.3 calling males/10ha), with higher densities recorded in settlements on the mainland of Pelješac Peninsula. Ecological density did not correlate with the size of the settlement.
Summary		Leta 1998 so bili na polotoku Pelješac (južna Dalmacija, Hrvaška) popisani pojoči samci velikega skovika Otus scops v 18 naseljih na območju, velikem 93 kmz. Uporabljena je bila metoda izzivanja s posnetkom. Preštetih je bilo 90 pojočih samcev velikega skovika. Avtor ocenjuje, da je populacija velikih skovikov, gnezdečih v urbanih okoljih, leta 1998 na celotnem polotoku štela okoli 345 parov, ki naj bi po njegovem mnenju sestavljala tudi večji del na Pelješcu gnezdeče populacije z ocenjeno gostoto 10 15 parov/10km2. Celotna populacija velikega skovika na Pelješcu je ocenjena na 230 do 575 parov. V delu so predstavljene tudi ekološke gostote urbano gnezdeče populacije v različnih skupinah. Ekološke gostote so med skupinami zelo nihale (0.6 - 9.3 pojočih samcev/10ha), vendar so bile skupine z višjimi ekološkimi gostotami najdene le na celinskem delu polotoka. V raziskavi soodvisnost med velikostjo naselja in ekološko gostoto ni bila potrjena.
