Population justification: It is described as fairly common but usually localised and confined to large forests (V. Chartendrault in litt. 2008, Dutson 2011), being frequent in the south of Grande Terre but rarer in the north (Chartendrault and Barré 2005, 2006). A population also occurs on the Ile des Pins. The population size has not been formally estimated, though has previously been suspected to number between 10,000-20,000 birds (Chartendrault and Barré 2005, 2006, V. Chartendrault in litt. 2008). Assuming only a proportion of this estimate refers to mature individuals, the global population size is tentatively placed here in the range 8,000-15,000 mature individuals, although a direct quantification of the population size is required.

Trend justification: As an inhabitant of large fragments of primary forest, it is presumably sensitive to habitat modification and may be affected by habitat loss and degradation caused by fire, logging and mining. Mining of nickel, chromium, cobalt and iron has been suspected of causing habitat loss and degradation in some areas, and although core areas of habitat in the species' stronghold in the south of Grande Terre may be currently unaffected there is an increasing potential threat to these sites in the medium and longer term, especially as population density of the species appears to be twice as high on soils suitable for mining (V. Chartendrault in litt. 2008, G. Dutson in litt. 2009, C. Meresse in litt. 2009). Fire is an additional threat to primary forest on Grande Terre (G. Dutson in litt. 2009). Forest loss detected by remote sensing data is relatively low within the range, currently ongoing at a rate equivalent to 1% in three generations (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein). This however does not take into account additional impacts of degradation and, precautionarily, the species suspected to be declining slowly overall, though the rate of decline has not been quantified.
