Long-tailed Finch

The long-tailed finch (Poephila acuticauda) is a common species of estrildid finch found in northern Australia, from the Kimberley region to the Gulf of Carpentaria. It is a predominantly fawn-coloured bird with a pale grey head and prominent black bib and eyes. It inhabits dry savannah habitats in Australia and adapts readily to aviculture. It is known as the Hex finch in the United Kingdom, and Heck's finch in other parts of the world. == Taxonomy == The species Poephila acuticauda was first described by ornithologist John Gould in 1840, placing the new taxon as Amadina acuticauda. The specimen was collected by Benjamin Bynoe, the surgeon aboard HMS Beagle, at Derby on the north-west coast of Australia. It is one of three species in the genus Poephila. It is placed in the Australo-papuan finch family Estrildidae, although this family itself was previously placed in the sparrow family Passeridae. A variety of subspecific arrangements had been regarded as colour variation across an east to west cline, although the geographically distinct morphology came to be acknowledged in the late twentieth century. Further support was given in a genetic study published in 2005 showed that the two subspecies of the long-tailed finch were…
