Population justification: The global population size has not been quantified, but the species is reported to be the commonest large parrot within its range (del Hoyo et al. 1997). The species is still relatively abundant in forest habitat, at least on Guadalcanal (J. Wood in litt. 2019) and on Malaita (Callaghan et al. 2019), although it is rare on Rennell (Collar et al. 2020).

Trend justification: This species is inferred to be declining owing to ongoing forest loss and capture for trade. Data from Global Forest Watch (2021) suggest that between 2001-2020, the species's range experienced a loss of forest cover with at least 50% canopy cover of 6.8%, equivalent to a rate of 7.7% over three generations (23 years [Bird et al. 2020]). Extrapolating forwards, it is projected that between 8% (based on the 2000-2020 rate) and 14% (based on the 2016-2020 rate) of tree cover will be lost from the species's range.

The species does not seem to occur in agricultural land or urban environments (J. Wood in litt. 2019), suggesting that the population size is likely to decline as forest is lost, although it does occur within the Honiara urban area (M. O'Brien in litt. 2021), so its population may not be directly tied to the area of remaining tree cover.

The species is traded internationally for the caged bird trade, and data from CITES (2021) suggests that the level of trade has increased in recent years. It is also traded domestically in huge numbers (J. Wood in litt. 2019). However, the species remains common, and there is no indication that trapping is having a large effect on the species's population size at present (G. Dutson in litt. 2021, M. O'Brien pers. comm. 2021). The population is therefore suspected to be declining at a rate of less than 20% over three generations.
