Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 7 000 – 15 000 pairs
With patchy distribution over a considerable part of the country’s territory, mainly in the lowlands, but also in hilly and foothill regions. More compact along the Danube River, in the Danubian Plain, the Sofia Field, and in some other high plains in Western Bulgaria, the Sub – Balkan Valleys, along the river valleys of Maritsa, Tundzha, Struma, Arda, Mesta and their tributaries. With more dispersed localities in the forested or drier regions (Fore-Balkan, Strandzha, Eastern Rhodopes, etc.).
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 mainly in humid grassland and tall herb communities, especially those with ruderal vegetation (mostly Conium maculatum in combination with denser tall grasses and weeds). Common in fens, transition mires and springs, in water – fringe vegetation, mostly dry peripheries of reed beds, mixed with other grassy vegetation, especially Artemisia sp., Urtica dioica, Aristolochia clematitis and Rubus sp., in wastelands, crops and other (annual) grass crops, most often in wheat fields mixed with weeds. In many cases, nests in the outskirts of towns, villages, industrial sites, and sometimes even in public parks and large gardens, but its presence there is determined mainly by the presence of places with ruderal vegetation.
