Population justification: The eastern subspecies ruficauda may be extinct, and surveys of clarescens (confined to Cape York) estimated the population to number c.3,500 individuals (Garnett et al. 2011), however subclarescens is very common at Kununurra in association with the Ord River Irrigation Scheme and moderately common in the Victoria River District of the Northern Territory (Garnett and Crowley 2000). Therefore, the global population has been crudely estimated at c. 200,000 individuals.

Trend justification: On-going declines are thought to have slowed (and may have stabilised). Subspecies ruficauda is possibly extinct following historic declines but recent surveys suggest clarescens is stable in Cape York. Subspecies subclarescens is thought to be relatively stable as its habitat is protected by seasonal rains (S. Garnett in litt. 2006), but may be declining in the east of its range. Based on this information, the species is estimated to be declining slowly.
