| Summary: | As a result of special work in the middle and second half of September 2022 materials on the species composition and features of the passage of coastal birds in the water area of Lake Baikal were obtained. This season was characterized by very harsh conditions: low temperatures, early snowfall, constant storm winds. This is due to a sharp increase in air flows of the north- west direction (North Atlantic). In this regard, on the lake Baikal has recorded well-marked migrations of birds, previously very rarely observed in its waters: Heuglin’s Gull, Kittiwake and Vegae Gull. For the first time in a long period of research, the flight of a Great Skua was noted. The collected data emphasize the great influence of weather conditions in the Arctic on migration processes. A special study of these processes and the peculiarities of their development in various climatic situations is necessary ... |
