Ecological and Geographical Structure and Dynamics of Spring Migration of Passeriform Birds on the Putorana Plateau

Spring migration of passeriform birds on the Putorana Plateau follows distinct ecological and geographical patterns, characterized by asynchronous migratory waves with one dominant peak. Research spanning 1988–2007 identified 58 species migrating along river or lake shorelines, with population densities averaging 231 individuals/km². Migration timing varies significantly, from early arrivals like the horned lark (May 25–June 4) to late migrants such as the sand martin (June 7–16), with most species showing an 8-day interval between first appearances. The study highlights that migratory outbreaks coincide with low temperatures and precipitation, while closely related species exhibit varying synchronization in their migration peaks. This long-term analysis provides critical insights into the dynamics of avian spring migration in this UNESCO-listed region.
