Abstract

White crane belongs to common birds of passage of the Aldan upland region; 100 to 200 individuals are accounted visually during a season (up to 5 % of the population). Active passage is observed in May, 14-15 - 25-28, especially during the first days. The major part of white cranes migrating in spring takes the north-north-east direction.
