Population justification: Recent surveys have found this species to be widespread but patchy and at low population densities on the larger Fijian islands. Surveys recorded an average of 0.11 birds / hour (a total of 54 birds). Estimating an average pace 1 km / hour and an effective detection distance of 50 m each side of the trail suggests that about 1 bird was detected per km2, mostly calling males. There are a number of likely errors in this estimate, especially the number of silent birds overlooked. The species was recorded at about 50% of the sites surveyed (16/34 sites) which were pre-selected to be the densest old-growth rainforest. If it assumed to occur in 50% of the forest, which covers about 40% of the species' Fijian EOO of about 17,500 km2, the total population is estimated to be 2,500-9,999 birds (G. Dutson in litt. 2005). This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: On Fiji the species is declining in line with habitat loss, and probably the affects of introduced mongooses; elsewhere hunting is an additional threat. The species's global population is suspected to be declining at a moderate rate.
