Spring migrations of the Whooper swan and Bewick's swan were studied on a farm-land near the town of Olonets during 1997 - 2017. Usually the majority of swans crossed the territory of the agricultural landscape in transit, and only a small portion of the birds stayed on it for feeding for 1 - 2 days. In 2017, swans formed a mass migration stopover on the fields, 340 to 1,328 individuals were counted on it for 11 days, whose majority (about 90%) were Bewick's swans.
