Southern Migration Route and Wintering Grounds of the Common Crane of Dubna Premigratory Gathering

The transformation of arid ecosystems into agricultural lands around natural and man-made water reservoirs has led to the formation of large gatherings on the migration routes and wintering grounds of common cranes nesting in the center of the European part of Russia. The marking of the cranes of Dubna premigratory gathering with color rings made it possible to find birds during wintering in Israel in the Hula valley. The tracking of the marked cranes made it possible to find key areas on migration routes for the purposes of their conservation, as well as other possible locations of cranes from Dubna premigratory gatherings in Moscow Region and adjacent areas. The last one is especially important due to a reduction in the area of Dubna gathering and a decrease in the protective and fodder quality of this land.
