Breeding begins in August/September in the equatorial regions, and March/April in the southern end of the range. Sometimes they will form a tight colony, nesting in adjacent trees, but more often the colony is spread out. The male builds a rough, retort-shaped nest suspended from an acacia branch. When completed he will hang from the entrance, flapping his wings and calling. If a female accepts the nest she will line it with soft grasses and some feathers. He will then begin to defend a small area around the nest, and mate with the female. Once mated, he may build another nest and attract another female. Nestlings are fed seeds and insects, but data is not clear on parental responsibilities.
