In Siberia, breeds from southern steppes to northern taiga and forest-tundra. Rather common in steppe and forest-steppe, rare in the north; prefers open habitats.
Common, locally numerous, breeding migrant. Inhabits open lakes and marshes in steppe and desert, avoiding forest lakes; also locally in mountains up to 1500 m in Altai. Appears somewhat later than other ducks, in late April, or May in the north. Migrates in small flocks, often with other ducks, and movement finishes about mid-May. Nest is built on ground near water (sometimes up to 2 km away) under canopy of grass or bush and on dry tussocks at marsh edge. Shallow hollow lined with dry grass and down. Clutches of 7-10 eggs at end of April – mid-July. Female incubates 21-24 days. Juveniles hatch mid-June – end July and fly mid-July – early August. Repeat brood after loss of clutches is common. After females begin incubation, males fly away for moult in shallow steppe or desert lakes (end May, mainly June – early July). Autumn migration begins mid-August or early September, peak movement September.
