Population justification: The population in the Riverland Biosphere Reserve is estimated to contain c1,000 mature individuals, with 100-200 pairs in the Ngarkat / Big Desert / Wyperfield complex and 100 pairs in the Murray-Sunset / Hattah complex. Given that there are thought to be only small numbers in Scotia and central New South Wales, the total population is estimated to be no greater than 2,000 mature individuals (Garnett et al. 2011).
Trend justification: The species is suspected to be declining at a rate of 20-29% over three generations (19 years) owing to deteriorating habitat quality (Garnett et al. 2011).
