Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 0 pairs
Isolated sites during the breeding season on the Danube River, in the Mandra Lake, along the Maritsa River and Iskar River. All observations are made near significant migration corridors, which suggests that these sites are not breeding sites, but rather birds that spend the summer away from the main nesting area.
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.
Observed in non-marine waters – coastal lagoons, standing fresh waters, standing brackish waters, as well as in bogs, marshes, and humid grasslands on the banks of wetlands. Most of the wetlands in which the species is registered during the nesting season are artificial water bodies – fishponds and micro-dams.
