| Summary: | In the period from 2015 to 2023, the distribution and abundance of 26 protected bird species (including 18 nesting species) listed in the Red Books of Crimea, Sevastopol and the Russian Federation were clarified in Crimea. Two types of stations are important for the existence of a rare part of the nesting ornithocomplex: rocks (Phalacrocorax aristotelis, Falco peregrinus, Falco cherrug, Gyps fulvus, Columba livia, Coracias garrulus, Pastor roseus) and inland water bodies (Anser anser, Tadorna ferruginea, Charadrius alexandrinus, Himantopus himantopus, Recurvirostra avosetta, Sterna albifrons, Alcedo atthis). At least 14 species use aquatic biotopes during wintering, migrations and summer nomads (relatively large seasonal aggregations are formed by Anser anser, Tadorna ferruginea, Oxyura leucocephala, Himantopus himantopus, Recurvirostra avosetta), and, moreover, two species – Gavia arctica and Phalacrocorax aristotelis – nest off the sea coast). Three species (Anthropoides virgo, Burhinus oedicnemus, Granativora melanocephala) are registered in open biotopes, one species (Tyto alba) uses anthropogenic habitats. The Opuk (Phalacrocorax aristotelis, Falco cherrug, Charadrius alexandrinus, Himantopus himantopus, Recurvirostra avosetta, Columba livia, Pastor roseus, Granativora melanocephala) and Karadag Karadagsky (Phalacrocorax aristotelis, Falco cherrug, Falco peregrinus, Gyps fulvus, Columba livia) nature reserves continue to play a role as breeding grounds for protected bird species. Based on the obtained data, two locations important for the preservation of the rare ornithocomplex were identified: 1) Lake Kuchuk-Adzhigol (19 protected species, nesting Anser anser, Himantopus himantopus, Charadrius alexandrinus, Sterna albifrons); 2) the rocky ridge of Sarak-Kaya (Tadorna ferruginea, Falco cherrug, Falco peregrinus, Buteo rufinus and Coracias garrulus were recorded there during the nesting season).
