Abstract

Introduction. Kremenchuk reservoir plays an important role for waterbirds and wetland birds during seasonal migrations. Therefore, we provide the monitoring of the avifauna during seasonal migrations in the central part of the reservoir. The article details the results of the wetland birds and waterbirds censuses in the spring periods of 2014-2016.Purpose. To assess the species composition of wetland birds and waterbirds, their relative numbers, and seasonal dynamics in the spring period in the central part of the Kremenchuk reservoir. To compare the results with those obtained during 2007-2013.Methods. Bird censuses were conducted along the dam through the Kremenchuk Reservoir. Used the route-point method of censuses. In total 17 bird censuses were conducted (5-6 each year).Results. During the period of studies, 36 species of waterbirds and wetland birds were detected. The most numerous migratory species were Anser albifrons, Anas plathyrhynchos, A. penelope, Aythya fuligula, and Larus cachinans. Another 7 species can be considered common (Phalacrocorax carbo, Cygnus olor, Anser fabalis, Bucephala clangula, Fulica atra, Larus ridibundus, and L. canus). Five identified species are listed in the Red Data Book of Ukraine (Cygnus bewickii, Anas strepera, Bucephala clangula, Haliaeetus albicilla, and Haematopus ostralegus). The highest number of birds was observed in the second and third decades of March.Originality. Our data supplement the information on the species composition of wetland and waterbirds, their number, and dynamics in the central part of the Kremenchuk reservoir in the spring. The greatest impact on the number of birds at the local level have temperature, the area of ice cover, the water level in the reservoir.Conclusions. The central part of the Kremenchuk reservoir plays an important role for migratory waterbirds and wetland birds. A significant number of these birds (from 5 to more than 20 thousand) use this area for rest and feeding during the period of the spring migration. The most important for these birds part of the studied area is the water area of the Ornithological Reserve "Lypivskiy".Key words: migration, number, migration waves, phenology.
