Category of conservation concern (IUCN, 2020) \u2013 <\/i><\/b>Near threatened<\/span><\/p>\n Population size: <\/i><\/b>2020: 147 \u2013 466 pairs (2007: 150 – 230 pairs<\/span>)<\/b><\/p>\n Distribution pattern<\/i><\/b><\/p>\n Grouped and dispersed, mainly along the River Danube and the neighbouring areas of the Danubian Plain, the Black Sea coast, the Thracian Plain and Sofia Field. The most significant breeding sites are Srebarna Lake, Mechka, Orsoya and Pazardzhik Fishponds, Durankulak and Shabla Lakes, and the Dragoman Marsh. Distribution is heavily dependent on the water level of the wetlands in the breeding grounds, some of which dry up during certain years. Often when a particular breeding site disappears, new ones appear nearby. In 2002 after the marshes at Belene Island dried up, breeding pairs were observed at the micro-dams around Svishtov and the town of Belene.<\/span><\/p>\n Population estimation for the period 2013 – 2020:<\/b> During the period 2013-2020, the species was not found in some previous locations, in others there was a decline, but the increase in numbers in key locations due to the redistribution of pairs should be taken into account. The decrease in the numbers is observed mainly in the former fish farms, which are abandoned and the water regime is severely disturbed. The main breeding sites are in wetlands, which have been the focus of restorative activities, to which the species responds quickly and positively. The reduction in the number in Mechka and Orsoya fishponds, as well as in the Tsibarsko Marsh, related to the disturbed water regime and the drying up of part of the territory, is a matter of serious concern. The increased numbers in the area of the Burgas and the Mandra lakes are probably partly due to the redistribution of pairs from the Cherni Vrah fishponds, where the pairs have disappeared due to changes in the management of the fishponds. At the same time, due to the deteriorating environmental conditions in the Srebarna Lake the numbers have declined with nearly 30-40%.\u00a0<\/span><\/p>\n Population size in Special Protection Areas of Natura 2000:<\/b> 122-348 pairs (<\/span>75-83<\/span>% of the population).
