The numbers of birds and the vegetation structure were analyzed at 13, 7 and 10 leks of Great Snipes (Gallinago media) formed on agricultural lands in the Moscow Region in 2014 - 2016, respectively. Not less than 120 - 130 birds were concentrated on the leks annually, of which 82 - 94% were males. The abundance of Great Snipes changed asynchronously at different leks. It depended on neither the lek location (floodplain or watershed) nor the soil penetrability therein.
