Selekcia hniezdneho habitatu strnádky ciavej (Emberiza cia) v Národnom parku Slovenský kras

摘要: Breeding territories were determined based on regular counts of singing male Rock Buntings between April–July in 2003–2006. During the study period, 21–25 breeding territories per 16 ha per year were detected. Most of the breeding territories were defended during all the study years. In total, there were determined 34 unique breeding territories and 20 habitat patches interspersed between them. These patches were not defended by males during any of the study years. Ten habitat parameters were measured for both breeding and non-breeding habitat patches. The chance that a patch within a suitable habitat would be selected was significantly determined by the bush and stone cover, and by horizontal surface complexity (ditch density). Specifically, Rock Buntings in the study area selected for breeding patches showing relatively lower bush cover, relatively higher stone cover, and higher horizontal surface complexity. Breeding habitat selection in Slovakia was discussed taking into account the results reported for other populations of the species. The biological reasoning behind the habitat selection pattern in Rock Buntings was presented, and suggestions for habitat management were proposed.
