The population of both species increased significantly during the period 1999–2016, from 49 to 240 breeding pairs in 2016 for the Griffon Vulture, and from 6 to 12 for the Egyptian Vulture. At the same time, an increase in the two species’ distribution was also detected. Breeding parameters are generally stable, with a mean productivity of 0.62 chicks/pair starting incubation in the Griffon Vulture, and 0.86 chicks/pair in the Egyptian Vulture. Thus, favorable trends are present in both populations, although their situation is still delicate owing to their small population sizes.
