Population justification: This species is described as uncommon and very patchily distributed (Watling 2001, Dutson 2011, O'Brien and Masibalavu 2017), though locally fairly abundant (Morley 2018). In Vanuatu, Tongoa and Emae are thought to be strongholds for the species (Parr 2007). Elsewhere in Vanuatu it appears to be uncommon or rare however and may number only a few thousand in the country overall (G. Dutson in litt. 2024). Based on point count data from 2016, the Samoan population was estimated to number 3,660-5,500 individuals (O'Brien and Masibalavu 2017), suggesting the largest subpopulation exceeds 1,000 mature individuals if it is assumed that each island population corresponds to a distinct subpopulation. The global population has not been directly quantified, though given a large proportion of its range lies outside of Samoa it may exceed 10,000 mature individuals. Considering this species’ apparent rarity and that much of its range is poorly studied, it is here tentatively suspected to fall within the band 7,000-19,999 mature individuals. An accurate quantification is urgently required.

Trend justification: In Vanuatu there have been no recent records from several islands where the species was recorded in the past suggesting it has become locally extinct or very scarce, perhaps owing to extensive logging and forest clearance (Bregulla 1992, Birchenough 2003, Dutson 2011). The current population trend has not been quantified directly, though the species may be affected by ongoing habitat loss in part of its range. Remote sensing data are not available to estimate the rate of tree cover loss within Samoa, though forest loss across the species' range in Vanuatu remains low, equivalent to c.2% in ten years (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein). Although this does not account for additional impacts of degradation, this species occurs in secondary forest and open habitat and is considered to have a low forest dependency overall (Watling 2001, Dutson 2011, O'Brien and Masibalavu 2017). Opportunistic slingshot hunting of parrotfinches for food has been reported locally (Pratt and Mittermeier 2016, Morley 2018). It is also reportedly captured illegally for the caged bird trade, though numbers are likely small (Birchenough 2003, Golden 2014, Morley 2018). Precautionarily, the species is suspected to be declining slowly.
