In the present study we provide data on the presence of a Brown bear specimen in the Eastern Stara Planina (Eastern Balkan). We obtained camera-trap images and photographs of the footprints of bears from the region of Varbishki and Rishki passes (Varbishki Prohod and Rishki Prohod). The locations were positioned at over 100 km from the easternmost border of the core population of bears in the central Stara Planina. Our data indicate a potential bio corridor allowing at least for young bears to migrate east along the mountain.
