The reintroduction of Cinereous Vultures in Bulgaria has produced the first confirmed chicks in the Eastern Rhodopes since 1993, with three breeding pairs successfully hatching young as part of a coordinated EU-funded program.
The reintroduction of Cinereous Vultures in Bulgaria has produced its most significant result yet. Three pairs of these large birds have hatched chicks in the Eastern Rhodopes, ending a 33-year absence from the region. Monitoring teams from the Bulgarian Society for the Protection of Birds (BSPB) confirmed active nests with newly hatched young in April 2026.
This outcome took years of careful, coordinated effort to achieve. A formal reintroduction program launched in 2022 has released 40 Cinereous Vultures into the wild. The program is led by BSPB and supported by the Rewilding Rhodopes Foundation, GREFA, a Spanish wildlife rehabilitation organization, and Rewilding Europe.
The numbers tell an encouraging story. Eight pairs were recorded in the Bulgarian portion of the Eastern Rhodopes this year. Seven occupied artificial nests were built by conservation teams. Four began incubating eggs, and three successfully hatched chicks. That means 75% of incubating pairs produced young, a strong result for a newly established population.
Project leader Dr. Dobromir Dobrev described these results as visible proof that the effort is working. When birds return to a region and successfully raise young, it shows they have found adequate food, suitable nesting habitat, and enough safety to complete the full breeding cycle. That foundation is what allows a population to grow over time.
Why does the return of this bird matter so much? The Cinereous Vulture is Europe’s largest vulture species, with a wingspan reaching nearly three meters, roughly the length of a small car. These birds feed exclusively on animal carcasses, thereby serving as a natural form of sanitation. By consuming carrion quickly, they help prevent the spread of disease, support nutrient cycling, and maintain the surrounding ecosystem.
The reintroduction of the Cinereous Vultures in Bulgaria restores a natural sanitation system to European skies, as these massive birds, with wingspans approaching 3 meters, play a critical role in consuming carrion, preventing disease spread, and keeping ecosystems in balance.

Their value is not only ecological. Wildlife tourism centered on large raptors has become a real economic opportunity for local communities. A comparable study in France found vulture-watching drew more than 40,000 visitors annually to just two sites, injecting an estimated €1 to 1.4 million into local economies.
The birds released as part of the reintroduction of the Cinereous Vulture in Bulgaria are sourced from Spain, where the species has a stronger, more established population. Young birds spend several months in specially built aviaries at the release site before being released into the wild. A technique called hacking, where young birds are placed in artificial nests and fed without direct human contact for 20 to 30 days, eases their transition to independence.
This work does not stand alone. The Cinereous Vulture had already returned to Bulgaria’s Balkan Mountains as a breeding species in 2021, through a separate program called Vultures Back to LIFE, which recorded the first fledgling from reintroduced pairs in the country. Griffon Vultures, a related but distinct species, have also been successfully restored in Bulgaria through comparable long-term programs. When science-based reintroduction efforts are funded consistently and supported by local and international partners, they can reverse local extinctions.
Conservationists working on the reintroduction of Cinereous Vultures in Bulgaria point to community involvement as one of the most important factors in the program’s progress. Local landowners, businesses, and regional stakeholders all play a role in creating conditions that allow the species to establish and thrive.
The current effort is backed by the LIFE Rhodope Vulture project, co-funded by the European Union’s LIFE Program, the EU’s primary funding instrument for the environment and climate action. The project runs from June 2024 to May 2029, with a total budget of just over €4 million. It aims to increase food availability for vultures, address conflicts between wildlife and local landowners, and foster cooperation between conservation groups and businesses. It also has a cross-border dimension, working to conserve an existing colony in Greece’s Dadia-Lefkimi-Soufli National Park while building a new one in Bulgaria.
Long-term commitment is central to the success of programs like this. These birds take years to reach sexual maturity and produce only one chick per year, making patience and sustained funding essential. Similar lessons have emerged from bird reintroduction efforts worldwide, including the successful return of the Hawaiian crow to Maui, which showed that careful science and collaboration can restore a species after decades of absence.
According to the Vulture Conservation Foundation, many of the most remarkable wildlife comebacks of the last 50 years trace back to exactly this kind of slow, deliberate work. The reintroduction of the Cinereous Vultures in Bulgaria is now part of that story. Three chicks hatched in spring 2026 are not just a milestone. They are the starting point for what comes next.
