The current work presents the preliminary results of the Cinereous Vulture () releases in the Balkan Mountains in 2018-2022, aiming at the species re-introduction in Bulgaria, where it was listed as locally extinct since 1985. The first imports and releases of Cinereous Vultures in Bulgaria started in 2018. Until mid-2022, 72 individuals were released in the Eastern Balkan Mountains (Kotlenska Planina SPA and Sinite Kamani Nature Park) and Vrachanski Balkan Nature Park.

- The study reviews the successful re-introduction of the Griffon Vulture in Bulgaria's Eastern Balkan Mountains over an 11-year period from 2010 to 2020, with 153 birds released and a breeding population established.
- By 2020, the local population included around 80-115 vultures and 23-25 breeding pairs, showing signs of increasing productivity despite an average fledgling rate of only 0.41 per pair.
- Although there was a 33% mortality rate primarily due to electrocution shortly after release, the population is now considered successfully established, presenting the area as a vital source for future conservation efforts.
