“The Cinereous Vulture, listed as extinct as early as 1985 in the Red Book of Bulgaria and maintaining the same status in the 2011 edition, had not seen a single breeding pair until 2021. However, by 2024, the national population has surged to 18-20 pairs. Notably, 15-17 pairs, with at least 10 laying eggs, are situated in the two colonies Vrachanski Balkan/Ponor and Eastern Balkan Mountains…

During the current 2024 breeding period, the Griffon Vulture has achieved a record number in the autochthonous colonies in the Eastern Rhodopes, totalling 138 pairs.”
