Species Structure and Number of Birds of the Lower Tyligul Estuary in the Spring of 2019–2023

The aim of the work is to assess the dynamic characteristics of hydrophilic birds in the spring period of 2019–2023. Methods. In the open area, bird counts were carried out from a car with numerous stops to inspect territories and water areas using 10×, 12× binoculars and a 30–60× telescope. Observations were conducted on foot in areas with tree-shrub vegetation and along small water bodies. Registration of species was carried out both by visual observations and by the sounds of birds. Main results. 99 bird species of 13 orders were registered. Representatives of theorders Anseriformes, Gruiformes, Charadriiformes and Passeriformes dominated. Conclusions. Within the relatively little-changed natural complexes and in the adjacent territories and water areas of the region, relative stability of species diversity of birds and their quantitative characteristics has been observed in recent years. The population dynamics observed in some ecological groups of birds do not go beyond the normal fluctuations that are naturally inherent to them. Signs of an increase in the number of some species within the studied region in recent years can be associated with an increase in the level of danger in the eastern part of the Azov-Black Sea region in connection with military events.
