Thornbills (Acanthizidae)

Yellow-rumped Thornbill (Acanthiza chrysorrhoa) - HBW 12, p. 608

French: Acanthize à croupion jaune German: Gelbbürzel-Dornschnabel Spanish: Acantiza Culigualda
Other common names: Yellow-tailed Thornbill, Pallid/Yellow-rumped/Yellow-tailed Acanthiza, Pallid/Yellow-rumped/Yellow-tailed Tit, Pallid/Yellow-rumped/Yellow-tailed Tit-warbler, Yellowtail; Leigh’s Acanthiza, Leigh’s Tit/Tit-warbler (leighi)

Taxonomy: Saxicola chrysorrhoa Quoy and Gaimard, 1830, King George Sound, Western Australia.
Absence from Bass Strait islands suggests that Tasmanian race leachi may now be isolated. Geographical variation to some extent clinal, and all three mainland races appear to intergrade. Additional proposed races are ferdinandi (WC Australia, also Great Victoria Desert), which evidently relates to intergrading populations; sandlandi (coastal SC & SE Australia) and addenda (NW Victoria), both considered synonyms of leighi; and pallida (arid parts of Western Australia) and multi (humid SW Western Australia), both synonymized with nominate.
