Rare birds of prey observations in Kresna Gorge in Bulgaria

The Kresna Gorge of Struma River is found in south-west Bulgaria, between Pirin Mountain on the east and Maleshevska Mountain to the west (UTM, FM73). It represents a a rough terrain of silicate rocky habitats and degraded deciduous forests with Mediterranean climate influence. Following the re-introduction of Griffon Vulture (Gyps fulvus) by Fund for Wild Flora & Fauna in Kresna Gorge in 2010 and establishment of the feeding site for vultures (Stoynov & Peshev 2011, 2012, 2013), as well as increased ornithological observations in the area, related to the above, several rare species of birds of prey were observed or their regular presence was noticed. Some of them are new for the area, while others are considered extinct regionally. We herewith report on them.
