Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 300 – 500 pairs
With limited patchy distribution close to rocky areas with specific exposure and microclimate, mainly in the higher rocky parts of the Rila-Rhodope Massif and Central Stara Planina, but also in lower areas in these mountains.
Comparative distribution of the species compared to the first breeding birds atlas (Iankov, 2007): Breeding locality until 2007 | Breeding locality until 2007, confirmed after 2015 – | New breeding locality after 2015. – The breeding localities after 2015 are identified on a base of raw data from smartbirds.org.
Breeds exclusively on inland cliffs and exposed rocks, and sometimes close to entrances of caves. There are two types of exposed rocks preferred for nesting – in the high parts of the mountains (above the tree line) and in river valleys and gorges at lower altitudes. In the alpine zone breeds in the walls of chalets, substations and other isolated buildings in the mountains.
