The Variegated Fairywren is a fairywren that lives in diverse habitats spread across most of Australia. Four subspecies are recognised. Exhibiting a high degree of sexual dimorphism, the brightly coloured breeding male has chestnut shoulders and blue crown and ear coverts, while non-breeding males, females and juveniles have predominantly grey-brown plumage. Notably, females of the two subspecies rogersi and dulcis have mainly blue-grey plumage. Like other fairywrens, the Variegated Fairywren is a cooperative breeding species, with small groups of birds maintaining and defending small territories year-round. Groups consist of a socially monogamous pair with several helper birds who assist in raising the young. Male wrens pluck yellow petals and display them to females as part of a courtship display. These birds are primarily insectivorous and forage and live in the shelter of scrubby vegetation across 90% of continental Australia, which is a wider range than that of any other fairywren.
