Breeding: In the north they breed between Feb and May while the southern birds breed in the winter, Jun to Sept. They mate for life; sometimes pairs can be found alone sometimes they can form large colonies with hundred of pairs. The clutch consists of five to ten pale green eggs laid in a large messy nest made from a pile of reeds and other grasses about 100cm across, usually located on an island or in shallow water.
