The long-tailed finch (Poephila acuticauda)
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.
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.[4] Further support was given in a genetic study published in 2005 showed that the two subspecies of the long-tailed finch were separated from each other by the Kimberley Plateau–Arnhem Land Barrier around 340,000 years ago, and their ancestors diverged from the black-throated finch (P. cincta) across the Carpentarian Barrier 600 thousand years ago.
The species maintain a simple pair bond, with some records of extended family groups or in small flocks; the pairs remain in close proximity when engaged in their activities. Individuals use song to identify themselves to a partner, and they maintain contact with a 'distance call'[4] Male P. acuticauda approach unfamiliar members of the species and engage in a courtship display, holding themselves in an upright posture and singing, before attempting to mate with the newcomer. Male newcomers will sometimes not declare their sex when confronted by a group of birds. The authors of the study propose this is a survival mechanism to reduce harassment, increase chances of acceptance into the group and hence chances of future reproduction.
