Maluridae – Australasian Wrens
The Maluridae are a family of small, insectivorous passerine birds endemic to Australia and New Guinea. Commonly known as wrens, they are unrelated to the true wrens of the Northern Hemisphere. The family includes 15 species of fairywren, 3 emu-wrens, and 11 grass wrens.
They are small birds, inhabiting a wide range of environments, from rainforest to desert, although most species inhabit grassland or scrub. The grasswrens are well camouflaged with black and brown patterns, but other species often have brilliantly coloured plumage, especially in the males.
They are insectivorous, typically foraging in underbrush. They build domed nests in areas of dense vegetation, and it is not unusual for the young to remain in the nest and assist in raising chicks from later clutches.
Fairywrens are notable for several peculiar behavioural characteristics. They are socially monogamous and sexually promiscuous, meaning that although they form pairs between one male and one female, each partner will mate with other individuals and even assist in raising the young from such pairings. Males of several species pluck petals of conspicuous colours and display them to females, a behaviour yet to be explained.
The songs of fairywrens is pleasant and complex, and at least two species (superb and splendid), in addition to the alarm calls common to most small birds, have another vocalisation used when confronted by predators. This ‘Type II Vocalisation’, is song-like and used when confronted by calling butcherbirds, and sometimes other predatory birds. Its purpose is not yet understood; it is certainly not a warning call.
According to the IOC, there are just 30 species in this family; they are:

Grey Grasswren Amytornis barbatusIUCN Species StatusThe global population size has not been quantified, but the species is reported to be rare in Queensland and South Australia and vulnerable in New South Wales (Higgins et al. 2001). The nominate barbatus may number c.15,000 individuals.

Grey Grasswren Amytornis barbatusSpecies AccountThe grey grasswren (Amytornis barbatus) is a passerine bird of the family Maluridae native to inland Australia. It is a rarely seen elusive bird that was first sighted in 1921, but not taxonomically described until 1968.
Lovely Fairy-wren Malurus amabilisSpecies AccountImage + Lovely Fairy-wrens are co-operative breeders. Genetic studies of superb and splendid fairy-wrens have revealed the shocking fact that a high proportion of the young are not dad`s. It appears that, from time to time, mum entertains the neighbouring males, mating with up to six different ones in addition to her regular partner…

Lovely Fairy-wren Malurus amabilisSpecies AccountThe lovely fairywren (Malurus amabilis) is a species of bird in the Maluridae family. It is endemic to northeastern Australia. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests.
Mallee Emu-wren Stipiturus malleeSpecies AccountThe Mallee Emu-wren (Stipiturus mallee) is a bird species in the family Maluridae. It is endemic to Australia. Its natural habitat is temperate grassland. It is threatened by habitat loss.
Mallee Emu-wren Stipiturus malleeSpecies AccountSound archive and distribution map
Mallee Emu-wren Stipiturus malleeIUCN Species Status13-14.5 cm. Tiny-bodied, streaked wren with brown, filamentous tail of 8-9.5 cm. Grey-brown upperparts, coarsely streaked darker. Rufous cap. Orange-buff below in both sexes. Male has sky-blue face and bib.
Red-backed Fairy-wren Malurus melanocephalusBirdLife Species AccountWhile many of Australia’s fairy-wrens feature various shades of blue in their plumage, the Red-backed Fairy-wren is equally as striking, but with an eye-catching patch of red feathers on its back and rump, contrasting with the rest of the plumage, which is glossy black. They are commonly seen in grassy areas of northern and eastern Australia.
Red-backed Fairy-wren Malurus melanocephalusSpecies AccountThis is the smallest of the fairy-wrens, with the male in breeding plumage inmistakable; glossy black with a scarlet saddle, black bill and shortish tail with a squared tip. Adult non-breeding males and immature birds are very similar to the females which are plain warm-brown with a pinkish-brown bill, though males have a black bill. The tail of the females is longer and more pointed. These wrens have no blue in their plumage at all. They are usually in small family groups with mainly brownish birds.
Red-backed Fairy-wren Malurus melanocephalusIUCN Species StatusThis species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion.

It is endemic to Australia and can be found near rivers and coastal areas along the northern and eastern coastlines from the Kimberley in the northwest to the Hunter Region in New South Wales.
Variegated Fairy-wren Malurus lambertiSpecies AccountThe breeding male Variegated Fairy-wren is brightly coloured. The crown and sides of the head are blue, and the shoulder patch is a rich chestnut. The depth and variety of colours in the male varies among the four subspecies, distributed across the Australian mainland. Non-breeding males, females and young birds are brownish grey. Females
