Purple-crowned Fairy-wrens are territorial and will defend their territory (Rowley 1988: 5). This species is also sedentary and will stay in a region for many years. Male offspring tend to stay close to the monogamous breeding pair and help raise young for up to 4 years. Individuals in this species keep contact with other individuals when foraging by using a “chet” call. Purple-crowned Fairy-wrens are insectivores but can also feed on leaf matter that can get trapped on Pandanus or other canegrass (Rowley & Russel 1993).
