Wallace's Fairywren

Identificazione

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.<p>Little is known about its vocalisations, but hissing see see see see calls are given by foraging parties.

Tassonomia

The Wallace's fairywren is the only member of the monotypic genus Sipodotus.<p>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.<p>The species' specific epithet is named after Alfred Russel Wallace, a British naturalist, explorer, geographer, and biologist. the generic name Sipodotus is an anagram of Todopsis. Alternate names for Wallace's fairywren include the blue-capped fairywren, Wallace's wren, and Wallace's wren-warbler.<p>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).<p>There are two recognized subspecies:

Areale e 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. 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.<p>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.
