Data on the distribution and abundance of the Great Snipe in northwestern Russia and in neighboring Finland over the past 150 years are summarized. There was a decrease in the number of birds, which went from west to east, in this part of the range in the 20th century. The Finnish population declined to a critical level by the middle of the 20th century; a noticeable decline in the number of birds occurred in the 1960s-1970s in the Leningrad region and in the 1980s in Karelia. At present, the Great Snipe retains the status of a breeding and migratory species in the region, but its distribution area continues to shrink and break up into fragments, and its northern border has receded to the south and southeast. The Great Snipe is sporadically distributed throughout the Leningrad and Vologda regions, but it now breeds in separate isolated groups to the north of these borders: in Karelia and the Arkhangelsk region. In Karelia, the range boundary receded from 63 degrees to 62 degrees N, and it is limited to lands located near the shores of lakes Ladoga and Onega. In the western part of the Arkhangelsk region, birds are occasionally found up to 62 degrees-63 degrees N during breeding time; along the floodplain of the Northern Dvina, they reach Arkhangelsk; near the eastern border of the region, they go up to 65 degrees; and in the western part of the Nenets Autonomous Okrug, up to 67 degrees N. A lack of data does not allow us to indicate the exact boundary of the range of the species, but the obtained results can serve as a starting point for further studies of its distribution.
