Distribution of the blue-breasted fairywren

The blue-breasted fairywren (Malurus pulcherrimus), or blue-breasted wren, is a species of passerine bird in the Australasian wren family, Maluridae. It is non-migratory and endemic to southern Western Australia and the Eyre Peninsula in South Australia. Exhibiting a high degree of sexual dimorphism, the male adopts a brilliantly coloured breeding plumage, with a bright blue crown, ear coverts and upper back, red shoulders, contrasting with a dark blue throat, grey-brown tail and wings and pale underparts. Non-breeding males, females and juveniles have predominantly grey-brown plumage. No separate subspecies are recognised.

Taxonomy and systematics

John Gould described the blue-breasted fairywren in 1844. Its species name is the Latin adjective pulcherrimus "very pretty".

It is one of eleven species of the genus Malurus , commonly known as fairywrens, found in Australia and lowland New Guinea. [2] Within the genus it belongs to a group of four very similar species known collectively as chestnut-shouldered fairywrens. The other three species are the lovely fairywren, the variegated fairywren, and the red-winged fairywren. [3] Molecular study showed the blue-breasted fairywren to be the most closely related to the red-winged fairywren. [4]

Like other fairywrens, the blue-breasted fairywren is unrelated to the true wrens. Initially fairywrens were thought to be a member of the Old World flycatcher family Muscicapidae or warbler family Sylviidae before being placed in the newly recognised Maluridae in 1975. [5] More recently, DNA analysis has shown the family to be related to the honeyeaters (Meliphagidae) and the pardalotes (Pardalotidae) in a large superfamily Meliphagoidea. [6] [7]

Evolutionary history

In his 1982 monograph, ornithologist Richard Schodde proposed a northern origin for the chestnut-shouldered fairywren species complex due to the variety of forms in the north and their absence in the southeast of the continent. [8] Ancestral birds spread south and colonised the southwest during a warmer and 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 the loss of habitat and fragmentation of populations. South-western birds gave rise to what is now the red-winged fairywren, while those in the northwest of the continent became the variegated fairywren. Continuing 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 12,00013,000 years ago, the northern variegated forms have again spread southwards. This has resulted in the ranges of all three species overlapping. [8]

The contact call is a soft, short reed-like trill. The alarm call is the typical Malurus short churring notes repeatedly spat out and taken up by all members of the group. The males have the least distinctive song of the Australasian wren family; a soft whirring, buzzing trill, usually given from a sheltered vantage point deep within the foliage of shrubby vegetation.

Distribution and habitat

The range of the blue-breasted fairywren is inland south-western Western Australia and the Eyre Peninsula of South Australia. Originally it was thought to only occur in Western Australia, but was later found in the more eastward area, where it was for some time mistaken for one of the many forms of the variegated wren. The distribution of the species is unusual in that there is a gap in their range of three hundred kilometres; from the head of the Great Australian Bight to their reappearance on Eyre Peninsula.

Behaviour and ecology

It is not a common species, and being secretive by nature it is not an easy bird to observe. However, the females may be induced to show themselves if the wren distress call is imitated. The adult males are even more shy than the females and are usually only glimpsed skulking in the bushes.

Breeding

The comparatively short breeding season is from August to November. This means the species usually only has time to raise one, sometimes two, clutches per year. Only females have been observed nest building, and brooding the eggs and young. The time taken to complete a nest is roughly a week. The average clutch consists of three ovoid creamy eggs speckled with coarse smudges and blotches of reddish-brown, particularly on the larger end.

Little is known of the incubation period and the rearing of the young, but these tasks are probably similar in nature to the other closely related members of the wren family. However, both parents, and other members of the individual family group, have been observed feeding the nestlings.

If the nest, or young, are threatened both adult sexes employ the “rodent-run” predator distracting technique typical of the Maluridae.

Feeding

Blue-breasted wrens are predominantly ground feeders, taking beetles, grubs, ants, weevils flies, wasps and other small invertebrates.

<span class="mw-page-title-main">Superb fairywren</span> Species of bird

The superb fairywren is a passerine bird in the Australasian wren family, Maluridae, and is common and familiar across south-eastern Australia. It is a sedentary and territorial species, also exhibiting a high degree of sexual dimorphism; the male in breeding plumage has a striking bright blue forehead, ear coverts, mantle, and tail, with a black mask and black or dark blue throat. Non-breeding males, females and juveniles are predominantly grey-brown in colour; this gave the early impression that males were polygamous, as all dull-coloured birds were taken for females. Six subspecies groups are recognized: three larger and darker forms from Tasmania, Flinders and King Island respectively, and three smaller and paler forms from mainland Australia and Kangaroo Island.

<span class="mw-page-title-main">Splendid fairywren</span> Species of bird

The splendid fairywren is a passerine bird in the Australasian wren family, Maluridae. It is also known simply as the splendid wren or more colloquially in Western Australia as the blue wren. The splendid fairywren is found across much of the Australian continent from central-western New South Wales and southwestern Queensland over to coastal Western Australia. It inhabits predominantly arid and semi-arid regions. Exhibiting a high degree of sexual dimorphism, the male in breeding plumage is a small, long-tailed bird of predominantly bright blue and black colouration. Non-breeding males, females and juveniles are predominantly grey-brown in colour; this gave the early impression that males were polygamous as all dull-coloured birds were taken for females. It comprises several similar all-blue and black subspecies that were originally considered separate species.

The purple-crowned fairywren is a species of bird in the Australasian wren family, Maluridae. It is the largest of the eleven species in the genus Malurus and is endemic to northern Australia. The species name is derived from the Latin word cǒrōna meaning "crown", owing to the distinctive purple circle of crown feathers sported by breeding males. Genetic evidence shows that the purple-crowned fairywren is most closely related to the superb fairywren and splendid fairywren. Purple-crowned fairywrens can be distinguished from other fairywrens in northern Australia by the presence of cheek patches and the deep blue colour of their perky tails.

The red-winged fairywren is a species of passerine bird in the Australasian wren family, Maluridae. It is non-migratory and endemic to the southwestern corner of Western Australia. Exhibiting a high degree of sexual dimorphism, the male adopts a brilliantly coloured breeding plumage, with an iridescent silvery-blue crown, ear coverts and upper back, red shoulders, contrasting with a black throat, grey-brown tail and wings and pale underparts. Non-breeding males, females and juveniles have predominantly grey-brown plumage, though males may bear isolated blue and black feathers. No separate subspecies are recognised. Similar in appearance and closely related to the variegated fairywren and the blue-breasted fairywren, it is regarded as a separate species as no intermediate forms have been recorded where their ranges overlap. Though the red-winged fairywren is locally common, there is evidence of a decline in numbers.

<span class="mw-page-title-main">White-winged fairywren</span> Australian species of bird

The white-winged fairywren is a species of passerine bird in the Australasian wren family, Maluridae. It lives in the drier parts of Central Australia; from central Queensland and South Australia across to Western Australia. Like other fairywrens, this species displays marked sexual dimorphism and one or more males of a social group grow brightly coloured plumage during the breeding season. The female is sandy-brown with light-blue tail feathers; it is smaller than the male, which, in breeding plumage, has a bright-blue body, black bill, and white wings. Younger sexually mature males are almost indistinguishable from females and are often the breeding males. In spring and summer, a troop of white-winged fairywrens has a brightly coloured older male accompanied by small, inconspicuous brown birds, many of which are also male. Three subspecies are recognised. Apart from the mainland subspecies, one is found on Dirk Hartog Island, and another on Barrow Island off the coast of Western Australia. Males from these islands have black rather than blue breeding plumage.
