Thornbills (Acanthizidae)

Western Thornbill (Acanthiza inornata) - HBW 12, p. 606

French: Acanthize sobre German: Walddornschnabel Spanish: Acantiza Sencilla
Other common names: Western Tit-warbler, Bark/Master’s/Plain-coloured Tit

Taxonomy: Acanthiza inornata Gould, 1841, Swan River, Western Australia.
Genetically closest to A. reguloides, perhaps forming a superspecies with it. Proposed race mastersi (wettest portion of S coast of SW Australia, E to Albany) may be worthy of recognition, as sharp gradation occurs between darker population in extreme S and paler one to the N; further study required. Tentatively treated as monotypic.

Distribution: SW Western Australia; single record from E of Kalbarri, farther N in central subcoastal zone.
