The southern Tyumen region is a picturesque region. This area is characterized by a valley of lakes that form a unified system, providing life for thousands of bird species. The film tells the story of geese, ducks, and other migratory birds that flock to the Tobol River estuary each spring, where they find refuge in the numerous lakes, marshes, and small rivers. You'll also encounter colonies of graylag geese, cormorants, and Dalmatian pelicans, who have chosen this region to breed.
