Category of conservation concern (IUCN, 2020) – Least Concern<\/i><\/b><\/p>\n
Population size: <\/i><\/b>2020: 14-60 pairs (2007: 5-25 pairs)<\/span><\/p>\n Distribution pattern<\/i><\/b><\/p>\n A very rare breeding species with a small population. It breeds alone or in small colonies – single or with other herons and cormorants. It has been established to breed in eleven sites during the period 2013-2018 – along the Danube River, in the Burgas Wetlands, in the Durankulak Lake, in the Dragoman Marsh and in two localities in the Upper Thracian Plain. In most places, it breeds irregularly. The only places where it builds its nests every year since 2007 are the Dragoman Marsh and Srebarna Lake. During the breeding season, late migrants or summer non-breeding individuals can be observed in many places in Northwestern Bulgaria, the Upper Thracian Plain, along the Iskar River, in the Eastern Rhodopes, along the Danube River and the Black Sea.<\/span><\/p>\n Population estimation for the period 2013 – 2020:<\/b> There is a certain increase in the number of the birds and the breeding sites compared to the maps presented in the Atlas of Breeding Birds of Bulgaria (2007) and in the Red Data Book of Bulgaria (2011).<\/span><\/p>\n Population size in Special Protection Areas of Natura 2000:<\/b> 14-55 pairs (93% of the population). The highest number is in the <\/span>Special Protection<\/span> Areas Rayanovtsi (10-20 pairs) and Srebarna (3-8 pairs)<\/span><\/p>\n [\/et_pb_text][et_pb_code _builder_version=”4.9.7″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]
