For the first time in 28 years after the last known nesting of black vultures in Bulgaria, the formation of three pairs in the Balkan Mountains has been registered. This has happened thanks to the efforts of Green Balkans environmentalists, the Fund for Wild Flora and Fauna and the Birds of Prey Protection Society. The birds nest on special platforms set up by conservationists as part of a long-term program to bring the species back to the country.

The black vulture used to be widespread throughout the country until the beginning of the twentieth century, but has been considered extinct in Bulgaria since 1985.
