Thornbills (Acanthizidae)

Chestnut-rumped Thornbill (Acanthiza uropygialis) - HBW 12, p. 605

French: Acanthize à croupion roux German: Braunbürzel-Dornschnabel Spanish: Acantiza Culirroja
Other common names: Chestnut-backed/Chestnut-tailed Thornbill, Chestnut-backed/Chestnut-rumped/Chestnut-tailed Tit, Chestnut-backed/Chestnut-rumped/Chestnut-tailed Tit-warbler

Taxonomy: Acanthiza uropygialis Gould, 1838, inland New South Wales, Australia.
Recent analysis of mitochondrial DNA suggests that this species may be close to A. iredalei; more study needed. Variation clinal, plumage becoming darker from N & W to S & E, and palest inland. Naming of geographical races moora (in SW Australia) and augusta (arid interior of S, E to Flinders Ranges, in South Australia) considered unwarranted. Monotypic.

Distribution: Semi-arid and arid zones of S Australia; absent from tropical N and from E seaboard.
