Population justification: The population has been conservatively estimated to be fewer than 2,500 mature individuals at the start of the breeding season, however more optimistic estimates have placed the total population as closer to c.10,000 mature individuals (J. Woinarski in litt. 2007).  A large proportion of flocks are however juveniles, there is a strong male biased sex ratio and genetic incompatibility between colour morphs (S. Pryke in litt. 2012) making a precautionary estimate important. The results of an expert panel review process concluded that the most plausible population size was c2,400 mature individuals in 2010, which potentially falls to an annual minimum close to 1,000 individuals during the wet season (Garnett et al. 2011).

Trend justification: Past declines appear to have ceased and, despite potential ongoing threats to its habitat from from grazing and fire management, the population is estimated to be stable (Garnett et al. 2011).
