The group often shelters and rests together during the heat of the day. Ancestral birds spread south and colonised the southwest during a warm wetter period around 2 million years ago at the end of the. Like other fairywrens, male variegated fairywrens have been observed carrying brightly coloured petals to display to females as part of a courtship ritual.
Insects are numerous and easy to catch, which allows the birds to rest between forays. These birds are primarily and forage and live in the shelter of scrubby vegetation east of the great dividing range. In this species, the petals that have been recorded have been yellow.
A clutch consists of three or four matte white with reddish-brown splotches and spots, measuring 12 mm 16 mm (0. Two or more broods may be laid in an extended breeding season. Birds in a group roost side-by-side in dense cover as well as engage in mutual preening.
The brightly coloured crown and ear tufts are prominently featured in breeding displays. Southwestern birds gave rise to what is now the red-winged fairywren, while those in the northwest of the continent became the variegated fairywren and yet another isolated in the northeast became the lovely fairywren. Further molecular studies may result in this hypothesis being modified.
The female incubates the eggs for 14 to 16 days, after which newly hatched nestlings are fed and their removed by all group members for 1012 days, by which time they are fledged. During spring and summer, birds are active in bursts through the day and accompany their foraging with song. Schodde also proposed that the blue-grey coloured females of the lavender-flanked subspecies were ancestral, while the browner coloration of females of southern forms was an adaptation to dry climates.
The depth and variety of colours in the male varies among the four subspecies, distributed across the australian mainland. The small groups actually consist of an adult female with younger or non-breeding birds. Cooler climate after this resulted in this being isolated as well and evolving into a separate species. Like other fairywrens, the variegated fairywren is a cooperative breeding species, with small groups of birds maintaining and defending small pair with several helper birds who assist in raising the young. Finally, after the end of the 12,00013,000 years ago, the northern variegated forms have again spread southwards, resulting in the.
The nest is an oval-shaped dome, constructed of grasses, and placed in a low shrub.

Some food may be found among the bark and foliage of short trees and grasses. Like other fairywrens, male variegated fairywrens have been observed carrying brightly coloured petals to display to females as part of a courtship ritual. They will moult again into nuptial plumage in winter or spring.
As they have a wide range, variegated fairy-wrens have been recorded breeding in almost every month of the year. The group often shelters and rests together during the heat of the day. Male wrens pluck yellow petals and display them to females as part of a courtship display. The crown and sides of the head are blue, and the shoulder patch is a rich chestnut. Ancestral birds spread south and colonised the southwest during a warm wetter period around 2 million years ago at the end of the. Females in the northern territory and western australian populations have a blue-grey (rather than brown-grey) plumage. Two or more broods may be laid in an extended breeding season. Mclean and colleagues of the former subspecies of the variegated fairywren largely supported schoddes hypothesis. Parents and helper birds will feed them for around one month.
