Breeds in small (on fresh water) or large (on salty lakes) colonies up to several hundred pairs, often with other gulls and terns. Nest is built on the dry reed heaps in water or on the ground in case of breeding on islands, nest is constructed from the dry reed stems, leaves and is lined with soft grass and feathers. Sometimes nests reach up to 30 cm in height, and 42-62 cm in base diameter. Clutches of 1-4 eggs is produced in April – May, or in June – July in case of first clutch loss.
