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

Spring migration of water and semiaquatic birds on the Putorana Plateau, spanning 1988–2007, reveals a dynamic ecological pattern dominated by tundra species (53% of Anseriformes and Charadriiformes) that migrate northward, eastward, and westward. Key stopover sites, particularly river deltas freed from snow early, support dense populations (15–227 ind./km), with the western plateau experiencing the highest migration intensity (20,000–30,000 individuals). The study identifies 68 species, distinguishing their distribution as universal (38%), local (22%), or point-specific (40%). Monospecific flocks dominate, and migration peaks from May 25 to June 17. Dominant species include common teal, Eurasian wigeon, northern pintail, grey-tailed tattler, and little stint.
