Materials on the waders of Northern Prikhubsugulye (Mongolia)

The article presents a comparative analysis of the materials on the species composition and population of waders in the northern Prikhubsugulye collected during the Mongol-Soviet complex Khubsugul expedition in 1970-1988 and during our visits to the northern shore of the lake in 2008-2019. In total, 34 waders were recorded in the northern Prikhubsugulye - 33 species in 1970-1988 and 27 species in 2008-2019. We have noted a decrease in the number and species diversity of waders, which is more likely conditioned by the unfavorable situation at wintering grounds.
