Southern Whiteface

The southern whiteface (Aphelocephala leucopsis) is a small passerine found in arid regions across most of the southern half of the Australian 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). The generic name derives from the Ancient Greek apheles 'simple' and kephale 'head'. The specific epithet derives from Ancient Greek leukos 'white' and opsis 'face'. 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 the whiteface beak compared with that of the scrubtit has been attributed to an increased dietary intake of seeds, requiring a more robust bill. == Description == The southern whiteface is a stocky thornbill-like bird with…
