Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 50 – 100 pairs
Dispersed with isolated breeding habitats, close to one another around Burgas, at the Northern Black Sea coast, in the Sofia Field and the former Straldzha Marsh, and at a distance from each other along the River Danube, the Thracian Plain, in Dobrudzha, Strandzha, and the Choklyovo Marsh. There may be habitats in other places in the country that have remained unidentified due to the the secretive behaviour and short calling season of the species. Distribution probably varies significantly in different years.
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.
