Biology

Common breeding migrant. Inhabits reed-rich lakes with shallow water, rarely visited by people. In spring arrives early April – early May. On Mangyshlak where Purple Heron not nested migration is very noticeable (singly and in groups of 5-7 birds) from mid-May, last birds recorded mid – end June. Nests in separate pairs and in small colonies, sometimes together with Grey Heron, Great Egret and Spoonbill. Nest is built by both partners on the heaps of old reeds from the reed stems and leaves, the available thorned twigs are also used. Clutch of 3-5, occasionally 6 eggs, is produced from early May to mid-June. Both parents incubate clutch for 24-28 days and feed nestlings which begin to fly roughly from July – early August. In autumn migrates in September; odd birds recorded to mid-October.
