Ecological and Geographical Structure and Dynamics of the Autumn Migration of Passerine Birds on the Putorana Plateau

Autumn migration of passerine birds on the Putorana Plateau follows distinct ecological and geographical patterns, with population density peaking during periods of cooler temperatures and no precipitation. The study, conducted over 16 years across eight sites covering 150,000 km², identified 42 species migrating along narrow forest-edge strips, primarily in southern or southwestern directions. Population densities ranged from 239 to 643 individuals/km², with the highest concentrations observed in the south of the plateau. Migration occurs in four well-defined waves, often synchronized by environmental conditions rather than species relationships. The majority of birds form monospecific or polyspecific flocks, with most species completing their migration in 20–26 days. Key species include the Arctic warbler, common redpoll, and little bunting, which dominate numerically.
