Southern whiteface : ウィキペディア英語版 | Southern whiteface
Endemic to Australia, the southern whiteface (''Aphelocephala leucopsis'') is a small passerine found in arid regions across most of the southern half of the continent, excluding Tasmania.〔 Superficially finch-like in appearance, this insectivorous bird is relatively common throughout most of its range, however, overall populations appear to be in decline.〔 ==Taxonomy== Originally classified as genus ''Xerophila'', the whitefaces were later reclassified when it was noted that a group of molluscs had already been ascribed that name and thus, are now listed as genus ''Aphelocephala''. There are three species within the ''Aphelocephala'', including the southern whiteface, banded whiteface (''A. nigricincta'') and chestnut-breasted whiteface (''A. pectoralis'').〔 Recent phylogenetic study has found whitefaces to be most closely related to the scrubtit (''Acanthornis magnus''), a monotypic Tasmanian species similar in appearance to ''Sericornis'' scrubwrens. The marked difference in the size and shape of Whiteface beaks compared with the Scrubtit has been attributed to an increased dietary intake of seeds, requiring a more robust bill.〔
