Migratory connections in waterfowl in the northern part of Western Siberia are discussed as based on ring recoveries from the database of the Bird Ringing Center of Russia, Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences. Altogether, 3531 recoveries from waterfowl of 29 species were used. The waterfowl in the region are characterized by exceptionally wide migratory connections, occurring in different seasons in most regions of the Old World within the Northern Hemisphere: from Iceland to the Japanese Islands and from West Africa to the Indian Subcontinent and the Yangtze River basin. The long-distance flights of birds to molting sites, the interannual change of nesting grounds and wintering regions, and the distribution on wintering grounds are discussed. Ten wintering regions have been identified. The available material on the migration of waterfowl is evaluated from the viewpoint of completing the description of their seasonal distribution and its significance in the study of the ecological connections of the territory of Western Siberia.
