The splendid fairywren (''Malurus splendens''), also known simply as the splendid wren or more colloquially in Western Australia as the blue wren, is a passerine bird of the Maluridae family. It 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. Like other fairywrens, the splendid fairywren is notable for several peculiar behavioural characteristics; birds 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 trysts.〔 Male wrens pluck pink or purple petals and display them to females as part of a courtship display.〔 The habitat of the splendid fairywren ranges from forest to dry scrub, generally with ample vegetation for shelter. Unlike the eastern superb fairywren, it has not adapted well to human occupation of the landscape and has disappeared from some urbanised areas. The splendid fairywren mainly eats insects and supplements its diet with seeds. ==Taxonomy== The splendid fairywren is one of 12 species of the genus ''Malurus'', commonly known as fairywrens, found in Australia and lowland New Guinea.〔.〕 Within the genus it is most closely related to the superb fairywren. These two "blue wrens" are closely related to the purple-crowned fairywren of north-western Australia.〔.〕 Specimens were initially collected at King George Sound, and the splendid fairywren then described as ''Saxicola splendens'' by the French naturalists Jean René Constant Quoy and Joseph Paul Gaimard in 1830,〔Quoy, J.R.C. and Gaimard, J.P. in Dumont-d'Urville, J. (1830). ''Voyage de découvertes de l'Astrolabe exécuté par ordre du Roi, pendant les anneés 1826–1827–1828–1829, sous le commandement de M.J. Dumont-d'Urville''. Zoologie. Paris: J. Tastu Vol. 1 i p197〕 three years before John Gould gave it the scientific name of ''Malurus pectoralis'' and vernacular name of ''banded superb-warbler''.〔Gould, J. (1833). Untitled. ''Proc. Zool. Soc. Lond.'' 1:pp106–107〕 Though he correctly placed it in the genus ''Malurus'', the specific name of the former authors took priority. The specific epithet is derived from the Latin ''splendens'', which means "shining". Like other fairywrens, the splendid fairywren is unrelated to the true wren. It was first classified as a member of the Old World flycatcher family Muscicapidae by Richard Bowdler Sharpe, though it was later placed in the warbler family Sylviidae by the same author, before being placed in the newly recognised Maluridae in 1975. More recently, DNA analysis has shown the family to be related to Meliphagidae (honeyeaters), and the Pardalotidae in a large superfamily Meliphagoidea. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Splendid fairywren」の詳細全文を読む スポンサード リンク
