Migration stopovers play an important role in replenishing energy reserves during long migrations [1]. Every year, Sandhill cranes (Antigone canadensis canadensis) of the Alaska-Siberian subpopulation [2] fly an average of about 16,000 kilometers and hold the record for the longest migration among cranes of the genus Antigone. It is known that on the North American continent, during migrations, cranes of the mid-continental migratory population (which includes the Alaska-Siberian subpopulation) prefer wetlands located near agricultural complexes to reduce energy costs for local movements between food resources and resting places on water bodies [3, 4]. However, there are no complexes along the species’ flight route to Eurasia. To assess the potential expansion of the Sandhill crane in the northwest direction and the limits of its possible range in Eurasia, we compared anthropogenic and natural migratory stopovers based on the following parameters: the duration of the stopover and the length of the migratory rush after it
