Yellow-rumped Thornbill - Taxonomy

Taxonomy

The Yellow-rumped Thornbill was described as Saxicola chrysorrhoa by the French naturalists Jean René Constant Quoy and Joseph Paul Gaimard in 1830, from a specimen collected in King George Sound. Its specific epithet is derived from the Ancient Greek chryso- "golden", and orrhos "rump" or "sacral region". Four subspecies are recognised; the nominate chrysorrhoa of Western Australia, leachi of Tasmania, leighi of eastern Australia, and normantoni of central and northern Australia. Butterbum is a colloquial name used by Australian birdwatchers.
