Purple-crowned Fairy wrens are able to breed throughout the year but breeding is more common following wet seasons with good rainfall. These birds breed in monogamous pairs and can have a family group of 5-6 individuals that includes offspring from past reproductive events (http://www.australianwildlife.org/Wildlife-and-Ecosystems/Wildlife-Profiles/Birds/Purple-crowned-Fairy-wren.aspx). More males than females tend to stay and help raise new young. They also may stay for up to four years to help the breeding pair raise young (Rowley & Russel 1993).
A clutch containing 2 -3 eggs laid over successive days, is incubated by only females for 14 days. Females are also the only contributors to nest construction. Nests are dome-shaped and are “built close to the ground in thickets of Pandanus, river grass, or canegrass … [and] made from rootlets, grass stems, leaves and bar” (http://www.australianwildlife.org/Wildlife-and-Ecosystems/Wildlife-Profiles/Birds/Purple-crowned-Fairy-wren.aspx, Rowley 1988). Nests are often near openings “(e.g. drainage areas, roads, and tracks), perhaps to provide a better escape route for females from predators” (Van Doorn 2007). Nestlings remain in the nests for up to 10 days. Fledglings remain in dense cover for a week after leaving the nest because they cannot fly well (Rowley & Russel 1993). These young birds are still fed by members of the family group for at least 3 weeks (http://www.environment.gov.au/cgi-bin/sprat/public/publicspecies.pl?taxon_id=64442).
