Taxonomy and systematics

The Wallace's fairywren is the only member of the monotypic genus Sipodotus.

Wallace's fairywren was originally described in the genus Todopsis as Todopsis wallacii by G. R. Gray in 1862 on the basis of specimens collected by Charles Allen on Misool Island. Specimens from the Aru Islands were described as Todopsis coronata by John Gould in 1878. Mathews established the monotypic genus Sipodotus for the Wallace's fairywren in 1928 on the basis of the shape of the bill and the nearly identical plumages of the male and female of the species. The species has also been placed in the genus Malurus. When the species is placed in the genus Malurus, the subspecific name coronatus is preoccupied and is replaced with capillatus, coined by Mayr in 1986. [2]

The species' specific epithet is named after Alfred Russel Wallace, a British naturalist, explorer, geographer, and biologist. [3] the generic name Sipodotus is an anagram of Todopsis. [4] Alternate names for Wallace's fairywren include the blue-capped fairywren, Wallace's wren, and Wallace's wren-warbler.

Like other Australasian wrens, Wallace's fairywren is not related to the true wrens. The fairywrens were initially thought to be related to Muscicapidae (old-world flycatchers) or Sylviidae (warblers), before being placed in the Maluridae in 1975. Recently, DNA analysis has shown the Maluridae to be a part of the superfamily Meliphagoidea with the Pardalotidae (pardalotes) and the Meliphagidae (honeyeaters). [5]

Subspecies

There are two recognized subspecies:

Description

Wallace's fairywren is a small species of fairywren, 11–12.5 cm (4.3–4.9 in) in length and weighing 7–8 g (0.25–0.28 oz). Adult males have a black crown and nape with blue feather tips and a black face with an incomplete white eye-ring and white ear-tufts. The scapulars and back are rusty brown, with brownish-grey upperwings, white underparts, and brown tails. The black beak is long, broad, straight, and bluntly pointed, with a white tip. The iris is red-brown, with short, flesh-brown legs. Females are similar to males, but have a pale yellowish wash to the throat and a duller crown. Subspecies coronatus has a creamy wash to the underparts. Immatures are duller than the adults, with shorter bills and ear-coverts, along with having the crown be speckled buff instead of blue. [6]

Little is known about its vocalisations, but hissing see see see see calls are given by foraging parties. [6]

Distribution and habitat

Wallace's fairywren is endemic to New Guinea. It is common throughout New Guinea, except on the Huon Peninsula, eastern Sepik-Ramu, and most of the northern parts of the southeastern peninsula. [7] The species inhabits foothill rainforest and secondary growth between elevations of 100–800 m (330–2,620 ft), although they can be found up to elevations of 1,200 m (3,900 ft) and in lowland plains where there is suitable vegetation. [8]

It is typically found more in trees than in the undergrowth, most commonly from 2–10 m (6.6–32.8 ft) above the ground, but can be found from ground level to 40 m (130 ft) in the canopy. They most commonly inhabit trees with tangles of vines and climbing bamboo at forest edges. [8]

Behaviour and ecology

Breeding

Breeding occurs throughout the year, with a peak in September-December. Out of three observed nests, two were attended by three adults each. Nests are domed structures, with a hooded side entrance near the top, and are made out of fine grass, cobwebs, and strips of palm frond, lined with finer fibres and sometimes covered with bits of moss and epiphytes. Nests are placed in vines at a height of 5–10 m (16–33 ft) above the ground, although one nest was built in a 1–5 m (3.3–16.4 ft) tall shrub at the top of a 30 m (98 ft) tall cliff face. Eggs are thought to be laid in clutches of two. Chicks are fed by both parents once they hatch. [6]

Diet

Wallace's fairywrens are thought to be mainly insectivorous, feeding on insects and spiders. They forage by gleaning and probing in forest tangles and thickets. It has been known to forage with mixed species flocks, typically in family groups of 4-8 individuals. [8] [7]

Status

Wallace's fairywren is listed as least concern by the IUCN due to its large range and lack of significant population declines. They are common throughout foothill rainforest in their range. However, large-scale clearing of rainforest may be a potential threat. [1]

<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">Variegated fairywren</span> Species of bird

The variegated fairywren is a fairywren that lives in eastern Australia. As 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.

<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.
