Both sexes build the large nest which is a 1meter high mound of reeds, grasses and weeds which may be up to 1.5 metres diameter, in shallow water or on islands. The clutch of 4-8 greenish-white eggs are incubated for about 35-40 days. The young fledge about 6 months later. | Both sexes build the large nest which is a 1meter high mound of reeds, grasses and weeds which may be up to 1.5 metres diameter, in shallow water or on islands.
