- Аннотация: Ecological patterns of the spatial differentiation of bird fauna and populations in the alpine belt ofthe northwestern Putorana Plateau were analyzed at 730–1412 m above sea level. The survey was conductedby route counts along transects of unlimited width. The fauna of breeding birds was assessed using the speciesbelonging to faunal complexes and zonal-landscape groups. The similarity of the avifauna of the areas andhigh-altitude zones compared was determined using the Sørensen faunal coefficient. To identify the differences in the bird populations at various sites, the population similarity coefficient was utilized. The taxonomic structure and species composition of the breeding avifauna in the alpine belt of the northwestern Putorana Plateau are quite common and amount to 33 species. Two species, the red-necked stint, Calidris ruficollis(Pallas1776), and the long-tailed skua, Stercorarius longicaudus (Vieillot, 1819), were first recorded breedingin the alpine belt in the Putorana Plateau at a distance of 200 and 600 km, respectively, away from the southern borders of their main distribution areas. The taxonomic structure of the breeding avifauna corresponds tothe zonal and landscape features of the Arctic mountain regions with the dominance of species of Passeriformes and Charadriiformes, which together accounted for 80–88% of the overall diversity. The species ofthe Arctic faunal complex (52–62%) are the most significant in the formation of avifauna in the alpine beltof the Putorana Plateau. Zoogeographically, the avifauna of the alpine belt of the northwestern Putorana Plateau shows specific features due to Arctic–alpine (n = 5) and alpine (n = 1) species that are ecologicallyrelated to mountain landscapes. The avifauna of the alpine belt of the northwestern Putorana Plateau isformed within a system of general zonal-landscape and altitudinal belt patterns. The abundance and population density of birds in the alpine belt of the northwestern Putorana Plateau is much higher than in any otherpart of this belt. In the alpine belt of the northwestern Putorana Plateau, the species diversity, as well as birdpopulation density and abundance, of most species decreases progressively with altitude. During the breedingseason, 97% of species of local avifauna breed in the lower part of the alpine belt compared to 49% in its middle and lower parts. The population density of birds in the alpine belt in the northwestern Putorana Plateauis 264, 187, and 119 individuals per sq. km in its lower, middle, and upper parts, respectively.
