Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² or Area of Occupancy <2,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
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.
This species is endemic to the eastern Solomon Islands. It occurs on Savo, Guadalcanal, Malaita, Makira (San Cristobal), Ulawa, Ugi, Santa Ana, Santa Catalina and Rennell.
This species inhabits primary and secondary forest (Collar et al. 2020), but is more common in primary habitats and does not appear to utilise agricultural environments (Davies et al. 2015, J. Wood in litt. 2019), although it is seen fairly commonly within the limits of Honiara city (M. O'Brien in litt. 2021). It is common or fairly common at all altitudes (Danielsen et al. 2010, Callaghan et al. 2019).
This species is threatened by the loss of its forest habitat. Logging in the Solomon Islands is increasing, and the species does not seem to utilise agricultural or urban environments (J. Wood in litt. 2019). This species is also threatened by the domestic and international caged bird trade. Between 1998-2013, 4,930 wild-caught individuals were traded internationally (CITES 2021), roughly equivalent to c.380 individuals per year. Between 2014-2019, 4,163 individuals were traded internationally (CITES 2021), roughly equivalent to c.830 individuals per year, indicating that the demand for this species, and subsequent trade, has increased dramatically in recent years. 14,164 individuals labelled as captive bred birds were also traded between 1998-2013, and 50 were recorded between 2014-2019 (CITES 2021), however the Solomon Islands do not have any captive-breeding facilities or functioning registered breeders (Shepherd et al. 2012), suggesting that these birds were actually mislabelled wild-caught individuals, and therefore the true number of traded wild birds may be much higher. Between 2005-2014, this species made up 3.5% of birds imported into Singapore (Poole and Shepherd 2017).
Conservation Actions Underway
This species is listed under CITES Appendix II.
Conservation Actions Proposed
Reduce the level of domestic and international trade. Conduct population surveys to obtain a baseline population estimate. Ascertain the exact effects of trade and habitat loss on the species. Monitor population trends.
