Population justification: Its population is thought to number c.5,000 mature individuals, although this has little reliability. This equates to c.7,500 individuals in total.

Trend justification: Large-scale movements and sporadic appearances outside the western deserts make it difficult to determine whether there has been any change in distribution or numbers (Garnett and Crowley 2000). The decline in the numbers of records from the periphery of its range after 1950, however, suggests a contraction in range. This species has always been scarce, but an apparent reduction in sighting frequency from the eastern part of its range since the early 19th century suggests that there has been a decline in density over 50% of its range. The population is now considered to be fluctuating (Garnett and Crowley 2000).
