Population justification: The population size may not exceed 1,000 birds. It is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: The population is suspected to be in decline owing to the effects of fire, grazing by livestock and human disturbance (in the form of military actions against residual terrorist groups; R. Cheke in litt. 2007). However, there is no evidence to support the suspicion of a decline (R. Cheke in litt. 2007), and there is no estimate for the likely rate.
