The specific use of nesting territory by the lesser sandhill crane in Yakutia

The left Indigirka riverside in Yakutia is the western periphery of the habitat of the lesser sandhill crane. The size of its population, time budget, and use of territory during the nesting season were studied in the period from 1998 to 2007. The density of population of this species is much lower here than in the northwest of Chukotka and in Alaska, which is reflected in the specific behavior of broods. For a decade, the size of its population increased more than 20 times.
