The work is devoted to the study of ornithocomplexes of forest belts of different types. For the first time the current state of ornithocomplexes of forest belts of different types of the north-east of Ukraine was studied. The long - term and seasonal dynamics of the structure of ornithocomplexes of forest belts of different types of the northeast of Ukraine in the period are investigated. the obtained data are important for the development of measures for the protection and conservation of biodiversity of anthropogenically modified artificial biogeocenoses. A total of 68 species were recorded in avian communities occupying forest belts of different types. Thus, species diversity of forest belt avian communities of north-eastern Ukraine increases from 44 species (roadside forest belts) and 54 species (field protection forest belts) to 59 species (railside forest belts). The analysis of species diversity of avian communities is given as values of the indices of Shannon, Pielow, Margalef, Simpson, Berger-Parker, and Jaccard.The dominating species in the studied area are representatives of the European type of fauna, namely Parus major Linnaeus, 1758, Parus caeruleus Linnaeus, 1758, Emberiza calandra Linnaeus, 1758, Luscinia luscinia Linnaeus, 1758, etc. A numerous tropic group includes Fulica atra Linnaeus, 1758, Cuculus canorus Linnaeus, 1758, Milvus migrans Boddaert, 1783, etc. The boreal group is represented by Anas platyrhynchos Linnaeus, 1758, Motacilla alba Linnaeus, 1758, Motacilla flava Linnaeus, 1758. The conservation status of species was analysed. Thus, 4 species are listed in the Red Data Book of Ukraine (Milvus migrans Boddaert, 1783, Casarca ferruginea Pallas, 1764 Circus pygargus Linnaeus, 1758, Columba oenas Linnaeus, 1758); 6 are included in the Red Data Book of Kharkiv Region. 58 species are protected by the Berne Convention (Annexes II and III), 20 species are listed in the Bonn Convention (Annexes II and III), whereas the Washington Convention (B) protects 4 species. Another 5 bird species are included in the European Birds Directive. Some studied species belong to several protected categories at the same time, whilst 9 species of birds have no conservation status.
The floristic composition and structure were identified as the factors affecting the development of avian communities of linear plantations. The avifauna diversity of shelter belts ranges (in ascending order) from 26 species recorded in the rowanberry wind-blown forest belts, 38 breeding species and 2 species found foraging in mixed wind-blown forest belts, 39 species in the maple-ash wind-blown forest belts to 41 species encountered in maple-linden latticed forest belts. 44 species inhabit mixed dense and mixed latticed forest belts. The species composition of roadside forest belts in monofloral plantations (poplar and maple) is represented by 22 species. The avian community of mixed latticed forest belts consists of 43 species. The avian community of mixed forest belts near agrocenoses is represented by 46 species. Fifty-one species of birds are typical for mixed forest belts adjacent to water bodies. The species composition of birds of mixed forest belts located near settlements and anthropogenic facilities is represented by 44 species.
