| Population justification: Recent surveys on Fiji recorded an average of 0.1 birds/hour (a total of 49 birds) equating to 1 bird/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 55% of the sites surveyed (19/34 sites) which were pre-selected to be the densest wettest old-growth forest. Very few were recorded in logged or degraded forest. If it assumed to occur in 50% of the forest, which covers about 40% of the species's Fijian EOO (c.17,500 km2), the total population is likely to be in the range of 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: Given the species's intolerance of habitat degradation, it is likely to be declining at the same rate as forest loss and degradation, which is estimated to be about 0.5-0.8% per year (Claasen 1991), equating to 6-10% over 12 years (three generations). | ||||
