About the Yellow Thornbill

The yellow thornbill (Acanthiza nana), formerly known as the little thornbill, is a tiny passerine bird endemic to the eastern coast of Australia. While currently listed as Least Concern by the IUCN, the general consensus is that the population is decreasing.

Acanthiza nana was named by Irish zoologist N. A. Vigors and American naturalist Dr Thomas Horsfield in 1827, with the bird noted in the Sydney Cove area. However, the earliest field notes with type description record the yellow thornbill in 1803, with records sent at the time to the Linnean Society of London. The generic name Acanthiza derives from Ancient Greek akantheōn 'thorn-brake' and zaō 'live, inhabit'. The specific epithet nana is Latin for a 'female dwarf'. The yellow thornbill is one of 13 currently recognised species of thornbill within the genus Acanthiza. There are five species groups recognised within this genus, with the yellow thornbill (Acanthiza nana) most closely related to the striated thornbill (Acanthiza lineata). The only Acanthiza species which occurs outside Australia, the New Guinea thornbill (Acanthiza murina), also bears close molecular similarities to both the yellow and striated thornbills...
