The white-browed scrubwren (''Sericornis frontalis'') is a passerine bird found in coastal areas of Australia. Placed in the family Pardalotidae in the Sibley-Ahlquist taxonomy, this has met with opposition and indeed is now known to be wrong; they rather belong to the independent family Acanthizidae. It is insectivorous and inhabits undergrowth, from which it rarely ventures, though can be found close to urban areas. It is long and predominantly brown in colour with prominent white brows and pale eyes, though the three individual subspecies vary widely. Found in small groups, it is sedentary and engages in cooperative breeding. The larger Tasmanian scrubwren is sometimes considered a subspecies of this species. ==Taxonomy== The white-browed scrubwren was originally described by naturalists Nicholas Aylward Vigors and Thomas Horsfield in 1827. The specific epithet ''frontalis'' derived from the Latin ''frons'' "eyebrow". It is now divided into three subspecies: *''S. f. frontalis'', known as the white-browed scrubwren, is found in coastal eastern Australia from the New South Wales-Queensland border round to Adelaide in South Australia. *''S. f. laevigaster'', known as the buff-breasted scrubwren, is found in coastal Queensland from the New South Wales border north to the Atherton Tableland. *''S. f. maculatus'', known as the spotted scrubwren, occurs in coastal southern Australia, from Kangaroo Island and Adelaide westwards to Shark Bay in Western Australia. It is known to intergrade with the nominate subspecies where their ranges overlap. ''S. humilis'', the Tasmanian scrubwren, is found in Tasmania and Bass Strait islands and sometimes considered a subspecies of the white-browed scrubwren. It is larger at 13.5 cm long and lays larger eggs. 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「White-browed scrubwren」の詳細全文を読む スポンサード リンク
