Sažetak
During April 2005 all breeding pairs of Grey Wagtails were counted and registered on 16 major streams in the Medvednica Nature Park. The method included waterway survey and noting down all breeding pairs on topographic maps (1:25, 000). Altitude, slope and length of the reaches surveyed were also calculated from the maps. Supplementary habitat research was carried out at 20 locations with breeding pairs and at 20 locations without Grey Wagtails. The purposes of this research were to measure waterway dimensions, estimate the density and cover of the riparian vegetation and estimate human impact on these locations. In the Medvednica Nature Park, 75 pairs of Grey Wagtail bred on 16 streams with an average density of 7.6 pairs per 10 km, which is positively correlated with stream slope. There was a difference in the density and cover of the riparian vegetation between the breeding locations and those without Grey Wagtails. Differences were also recorded in relation to human impact at these locations, being higher at the breeding sites.
