Amadina acuticauda

King Sound, Western Australia

.

Race hecki sometimes treated as a separate species on basis of morphology (bill colour) and differences in quantitative genetics (although no genetic comparison made of races of other members of genus), and slight differences exist in songs and loud contact calls. Conversely, other authors have questioned whether two races are taxonomically recognizable, as distribution of yellow-billed and orange-billed birds is continuous across N Australia, with intergradation in W Northern Territory (and bill-colour differences do not persist in museum specimens); in addition, the two are similar in courtship behaviour, and in captivity individuals with no prior breeding experience do not mate assortatively. Further study required. Two subspecies currently recognized.
