Feeding conditions in breeding areas and selection of lekking sites by Great Snipe (Gallinago media) in Moscow Region, Russia
Great Snipe (Gallinago media) was included in the Red Data Book of the Moscow Region (central European Russia) after this species numbers had decreased dramatically in the 20th century. Certain range expansion and, particularly, growth of number of leks has been observed in Great Snipe in the north...
