The variegated fairywren (Malurus lamberti) is a fairywren that lives in eastern Australia. In a species that exhibits sexual dimorphism, the brightly coloured breeding male has chestnut shoulders and azure crown and ear coverts, while non-breeding males, females and juveniles have predominantly grey-brown plumage, although females of two subspecies 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 east of the Great Dividing Range. Populations across central, northern and western Australia were considered subspecies of this species until 2018, when they were reclassified as the purple-backed fairywren.

Taxonomy and systematics

The variegated fairywren was originally described by Nicholas Aylward Vigors and Thomas Horsfield in 1827, and was at first considered a colour variant of the superb fairywren. It is one of eleven species of the genus Malurus, commonly known as fairywrens, found in Australia and lowland New Guinea. Within the genus it belongs to a group of four very similar species known collectively as chestnut-shouldered fairywrens. There are well-defined borders between the variegated fairywren and the other chestnut-shouldered wrens in the group, which are the lovely fairywren, red-winged fairywren, and the blue-breasted fairywren. Gregory Mathews erected the genus Leggeornis for the group, with the variegated fairywren as the type species. However, the genus has been reclassified as a subgenus within Malurus.

Like other fairywrens, the variegated fairywren is unrelated to the true wrens. Initially, fairywrens were thought to be a member of the Old World flycatcher family, Muscicapidae, or the warbler family, Sylviidae, before being placed in the newly recognised Maluridae in 1975. More recently, DNA analysis has shown the family to be related to the honeyeaters (Meliphagidae) and the pardalotes (Pardalotidae) in a large superfamily Meliphagoidea.

"Variegated fairywren" has been designated the official name by the International Ornithologists' Union (IOC). The scientific name commemorates the British collector Aylmer Bourke Lambert. The variegated fairywren was formerly known as the variegated wren, until 1978 when the RAOU pushed for the current name to be used. It is also known as Lambert's wren.

Evolutionary history

In his 1982 monograph, ornithologist Richard Schodde proposed a northern origin for the chestnut-shouldered fairywren group due to the variety of forms in north and their absence in the southeast of the continent. Ancestral birds spread south and colonised the southwest during a warm wetter period around 2 million years ago at the end of the Pliocene or beginning of the Pleistocene. Subsequent cooler and drier conditions resulted in loss of habitat and fragmentation of populations. 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 warmer, humid conditions again allowed birds to spread southwards, this group occupying central southern Australia east to the Eyre Peninsula became the blue-breasted fairywren. Cooler climate after this resulted in this being isolated as well and evolving into a separate species. Finally, after the end of the last glacial period 12,000–13,000 years ago, the northern variegated forms have again spread southwards, resulting in the purple-backed fairywren. This has resulted in the variegated fairywren's range to overlap with all three other species. 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. Further molecular studies may result in this hypothesis being modified.

A 2017 molecular analysis by Alison J. McLean and colleagues of the former subspecies of the variegated fairywren largely supported Schodde's hypothesis. The Great Dividing Range was a major barrier and there is a deep genetic split between the variegated fairywren to its east, and the purple-backed fairywren to the west. In 2018, this split was recognized by the International Ornithological Committee with the subspecies to the north and west reallocated to the purple-backed fairywren.

The variegated fairywren is 14–15 cm (5.5–6 in) long and weighs 6–11 g (0.21–0.39 oz). Like other fairywrens, it is notable for its marked sexual dimorphism, males adopting a highly visible breeding plumage of brilliant iridescent blue and chestnut contrasting with black and grey-brown. The brightly coloured crown and ear tufts are prominently featured in breeding displays. The male in breeding plumage has striking bright blue ear coverts, with the crown often slightly darker, a black throat and nape, a royal blue upper back, chestnut shoulders and a bluish-grey tail. The wings are grey-brown and the belly creamy white. Non-breeding males, females and juveniles are predominantly grey-brown in colour; all males have a black bill and lores (eye-ring and bare skin between eyes and bill), while females have a red-brown bill and bright rufous lores. Immature males will develop black bills by six months of age, and moult into breeding plumage the first breeding season after hatching, though this may be incomplete with residual brownish plumage and may take another year or two to perfect. Both sexes moult in autumn after breeding, with males assuming an eclipse non-breeding plumage. They will moult again into nuptial plumage in winter or spring. The blue coloured plumage, particularly the ear-coverts, of the breeding males is highly iridescent due to the flattened and twisted surface of the barbules. The blue plumage also reflects ultraviolet light strongly, and so may be even more prominent to other fairywrens, whose colour vision extends into that part of the spectrum.


Vocal communication among variegated fairywrens is used primarily for communication between birds in a social group and for advertising and defending a territory. The basic song type is a high-pitched reel of a large number of short elements (10–20 per second); this lasts 1–4 seconds. The reel of the variegated fairywren is the softest of all malurids. Birds maintain contact with each other by tsst or seeee calls, while a short, sharp tsit serves as an alarm call.

Distribution and habitat

The variegated fairywren is found in scrubland with plenty of vegetation providing dense cover. They have been reported to shelter in mammal burrows to avoid extreme heat. In urban situations such as suburban Sydney, these fairywrens have been said to prefer areas with more cover than the related superb fairywren, though a 2007 survey in Sydney's northern suburbs has proposed that variegated fairywrens may prefer areas of higher plant diversity rather than denser cover as such. Forestry plantations of pine and eucalypts are generally unsuitable as they lack undergrowth.

Behaviour and ecology

Like all fairywrens, the variegated fairywren is an active and restless feeder, particularly on open ground near shelter, but also through the lower foliage. Movement is a series of jaunty hops and bounces, its balance assisted by a relatively large tail, which is usually held upright, and rarely still. The short, rounded wings provide good initial lift and are useful for short flights, though not for extended jaunts. During spring and summer, birds are active in bursts through the day and accompany their foraging with song. Insects are numerous and easy to catch, which allows the birds to rest between forays. The group often shelters and rests together during the heat of the day. Food is harder to find during winter and they are required to spend the day foraging continuously.

Like other fairywrens, male variegated fairywrens have been observed carrying brightly coloured petals to display to females as part of a courtship ritual. In this species, the petals that have been recorded have been yellow. Petals are displayed and presented to a female in the male fairywren's own or another territory.

The variegated fairywren is a cooperative breeding species, with pairs or small groups of birds maintaining and defending small territories year-round. Females and males feed young equally, while helper birds assist in defending the territory and feeding and rearing the young. Birds in a group roost side-by-side in dense cover as well as engage in mutual preening. Occasionally larger groups of around 10 birds have been recorded, though it is unclear whether this was incidental or a defined flock.

Breeding occurs from spring through to late summer; the nest is generally situated in thick vegetation and less than 1 m (3.3 ft) above the ground. It is a round or domed structure made of loosely woven grasses and spider webs, with an entrance in one side. Two or more broods may be laid in an extended breeding season. A clutch consists of three or four matte white eggs with reddish-brown splotches and spots, measuring 12 mm × 16 mm (0.47 in × 0.63 in). The female incubates the eggs for 14 to 16 days, after which newly hatched nestlings are fed and their fecal sacs removed by all group members for 10–12 days, by which time they are fledged. Parents and helper birds will feed them for around one month. Young birds often remain in the family group as helpers for a year or more before moving to another group, though some move on and breed in the first year. Variegated fairywrens commonly play host to the brood parasite Horsfield's bronze cuckoo and, less commonly, the brush cuckoo and fan-tailed cuckoo.

Food and feeding

The variegated fairywren consumes a wide range of small creatures, mostly insects, including ants, grasshoppers, bugs, flies, weevils and various larvae. Unlike the more ground-foraging superb fairywrens, they mostly forage deep inside shrubby vegetation, which is less than 2 m (7 ft) above the ground.


Major nest predators include Australian magpies, butcherbirds, laughing kookaburra, currawongs, crows and ravens, and shrike-thrushes, as well as introduced mammals such as the red fox, feral cats and black rat. The variegated fairywren readily adopts a 'rodent-run' display to distract predators from nests with young birds. The head, neck and tail are lowered, the wings are held out and the feathers are fluffed as the bird runs rapidly and voices a continuous alarm call.

Cultural depictions

The variegated fairywren appeared on a 45c postage stamp in the Australia Post Nature of Australia – Desert issue released in June 2002.
