The changes in the distribution/range of a particular taxon are among the most important criteria for determining its current status and the effective assessment of the implemented conservation measures. Determination of the geographic distribution/range is crucial for sensitive and rare species such as the White-backed Woodpecker (Dendrocopos leucotos). Therefore, we update the species distribution data on a 10×10 km UTM (MGRS) grid and compare it with the distribution map according to the Atlas of Breeding Birds in Bulgaria. In Bulgaria, the White-backed Woodpecker inhabits all mountains and some lowlands. The former distribution of the species extends within 122 UTM squares. According to our study (2008-2018), the species is distributed in 118 squares, including 52 squares where the occurrence of the species is reported for the first time. The species' presence was not confirmed in 57 squares. In addition, we estimated the population size and breeding density of the species in three SPAs: "Central Balkan," "Strandzha," and "Sredna Gora". [ABSTRACT FROM AUTHOR] |
