Breeding season: August to January, but late April recorded. They nest in swamps or lakes in a variety of vegetation types, such as rushes, grass, low shrubs and water-lilies. They may also nest on overhanging tree branches or on the ground. Some nests have a stage or track leading to them. Nests can vary from a flat, flimsy structure to a cup of fine, woven material, sometimes with a dome or with rushes interlaced over the nest. Nests are made of rushes or grass and lined with soft grass.
