Breeds in north-western Kazakhstan in south to Chapaevo village, location between Emba river and Mugodzhary ridge, and lower reaches of Turgay river. Probably breeds also between Ob and Irtysh valleys in south to Semipalatinsk. On migration occurs everywhere in plains.
Rare breeding and common passage migrant. Inhabits the wet meadows in river valleys and near steppe lakes, or the high-grassed shores of the saline-soil lake. On migration visits the shores of various reservoirs, the stubble fields or steppe lands far from the water. In spring appears in March – early April in southern areas, in April – early May in northern ones, arrives in small groups or flocks of 30-50, up to some hundred birds. First arriving males begin to mating-dance (in northern Kazakhstan in mid – end May, latest males arrive in early June). Then females appear. Female build the nest on tussock, among meadow or on island in colony of Terns and other waders; nest is located in shallow hole and is lined with dry grass. Clutches of 4 eggs is in third decade of May to early June. Alone female incubates for 21 days and cares for juveniles. The autumn migration begins in the end of June when the males with moulting collars and inner primaries gradually migrate in southern direction. In mid July females begin to migrate too, and juveniles move still later. Main stream of migration is in August – early September, the latest birds recorded in mid-September in northern areas, and in early November in southern ones. On Kyzykol lake in September 1-2 2005 about 20 thousand Ruffs were observed.
