Population justification: The population was estimated at between 400-500 pairs in 1988 (Robinson 1988 cited in Garnett et al. 2011). This is anticipated to have declined subsequently, hence the population is considered to presently be below 1,000 mature individuals, all in a single subpopulation.
Trend justification: While the population has been mentioned as appearing ‘secure’ since 1997, and this may be the case that inside the national park there has been little change since that time, there also have not been sufficient monitoring efforts anywhere to reliable gauge the trend. The anecdotal evidence provided in Garnett et al. (2011) in fact suggests that there may be an ongoing decline outside the park and the population was classified on a precautionary basis to be declining.
