Population justification: Currently there are probably c.300-350 pairs (C. Jones in litt. 2000), which is interpreted as indicating a population of 600-700 mature individuals, roughly equating to 900-1,100 individuals in total. However, caution may be necessary as the number of pairs is based on counts of singing males, and doubling these numbers may be misleading (R. Safford in litt. 2007). It is possible that the species exhibits a skewed sex ratio, in which case the effective breeding population would be lower than presently assumed (R. Safford in litt. 2007).

Trend justification: The population has increased since 1975, through expansion into lowland areas and an increase in density in traditional areas (Safford 1997; C. Jones in litt. 2000). Though there have been increases in some regions, declines are suspected in others (V. Tatayah in litt. 2012), therefore the current population trend is uncertain but suspected to be stable in the absence of further data.
