The Red Data Book Waterbirds in the Coastal Wetlands of the Azov-Black Sea Region of Ukraine β the Results of the August Counts 2018 and 2021
The article analyses data from the August Counts of 2018 and 2021, which covered the 40 most important wetlands on the Azov-Black Sea coast of Ukraine. Of the 106 wetland bird species recorded during the censuses, 35 species are listed in the Red Data Book of Ukraine. The number of them was about 50 thousand individuals or 7.6 % of the total number of counted birds: in 2018Β β 24.1 thousand individuals and in 2021 β 25.8 thousand individuals. Detailed information on the number of bird species and the list of the most important sites for each species can be found in the publication. The comparison of the current data with the previous survey period 2004β2015 (Chernichko et al., 2018) showed that the abundance of 17 waterbird species decreased, and 7 species increased their abundance. It is assumed that these changes are caused by the aridification of the climate, leading to the drying out of the shallow parts of the region's wetlands in the second half of the summer
Characteristics of Sex and Age Composition of Calidris Alpine (Aves, Charadriiformes) Migrating Across Sivash
The paper shows features of distribution based on regular captures and measurements since 1986 on two sites of Sivash (Central and Eastern), which are different in their hydrological regime and composition of forage macrozoobenthos. Shorter-billed males reliably prefer Central Sivash for storage of fat reserves at the expense of feeding on larvae of chironomids and possibly the brine shrimp. For longer-billed females it is more profitable to concentrate on Eastern Sivash, where they prefer to feed on polychaete worms. On basis of size characteristics of the captured birds and their time dynamics, the paper considers suggested terms of passage of different subspecies and populations of the Dunlin across the Azov-Black Sea coast of Ukraine. Also differences in age composition of migratory waders on different sites of Sivash are shown compared to other water bodies of the near Black Sea area.ΠΠ° ΠΎΡΠ½ΠΎΠ²Π°Π½ΠΈΠΈ ΡΠ΅Π³ΡΠ»ΡΡΠ½ΡΡ
