Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 100 – 400 pairs
Dispersed in the lowland areas throughout the country, mainly along the Black Sea coast, in the Sofia Field, and the former Straldzha Marsh, with isolated breeding sites along the Danube River, the Thracian Plain, the Danubian Plain, the Struma River Valley, etc. Due to the secretive behaviour and short calling season of the species, not all actual habitats are probably known.
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 in bogs and marshes, and especially in water fringe vegetation (usually in standing fresh waters). Favoured breeding habitats are marshlands, overgrown canals, fishponds, the shallow parts of micro-dams, etc.
