Ecological studies of the Ground Parrot have been on a state by state basis as each state in Australia has responsibility for its own wildlife.
Victoria was the first state to undertake a detailed study of the Ground Parrot, well ahead of such work in other states. At that time (1980) the Western Ground Parrot was considered to be a subspecies of the more widespread 'Eastern' Ground Parrot. The Victorian study was of the 'Eastern' Ground Parrot, but of interest to all who wanted to know more about these intriguing parrots.
