Abstract
After a research on spring migration of Falconiformes in 2011 and 2013, a key importance of the South Baikal migratory corridor as a zone of bird concentration in spring was discovered additionally to its well-known autumn importance. Conclusions on numbers, species list, and features of migratory behavior were made. During long-time observation of Falconiformes, three patterns of their migratory movement through the southernmost part of Lake Baikal were determined. The patterns depended on cloud, wind, and ice situation. The relation between migratory activity and meteorological situation on the migratory route was found. Species-specific differences in the birds’ reaction on weather changes during spring migration were shown on the example of four common migrating raptor species.
