Purple-crowned Fairy-wrens are mostly sedentary. They set up territories in the same place and can remain in the same territory year after year. The progeny will disperse in 1 to 3 years or stay with their parents for 4 years or more. The female progeny typically leave sooner and disperse farther away than the male siblings. The male progeny are more likely to stay with their parents and help care for their siblings. Individuals move away or find shelter in canopies of riverside eucalypts and paperbarks when their territory is flooded (Rowley 1988: 5). Local dispersal occurs when a breeding pair leaves their territory because of separation or death of one or both birds (Australian Government 2012). They would disperse one or two kilometers away. When a female bird loses her mate due to death, she will travel away from her territory to find a new mate. When a male bird loses his mate due to death, he will find a new mate in his territory. Helpers can move away to a group with breeding vacancies (Rowley 1988: 6).
