The northern border nesting on the left bank of Yenisei - 66-67 o N, the Yenisey - 67-68 o N (roughly coincides with the southern boundary of forest-tundra) on the right, this is far south of the border: on the available data - up to 63 o N The southern border of nesting is probably on the border of the southern taiga and podtaygi (Rogacheva, 1988).
Habitats. Occurs in the moss and osokovyh swamps, wet meadows, zarosshih peat, grassy banks of Forest Lakes, the large wetland felling (Ryabitsev, 2001). Phenology.
