Population justification: Line transects were surveyed for the species in lowland forest and mahogany plantations at Colo-I-Suva (Viti Levu) in 2003. If the species occurs at similar densities elsewhere on Viti Levu, extrapolation would give a total population of 130,000 calling birds for the whole island (D. Jackson in litt. 2005). Two other recent surveys, based on triangulated point-counts and estimates of territory size respectively, gave extrapolated figures of 25,000 pairs and 50,000 pairs for Viti Levu (White in litt. 2005).
Trend justification: A slow to moderate and on-going population decline is suspected, based on continuing habitat loss, although the species shows a degree of tolerance of degraded forest.
