Taxonomic note
Psittinus cyanurus and P. abbotti (del Hoyo and Collar 2014) were previously lumped as P. cyanurus following Sibley and Monroe (1990, 1993).

Population justification: The population size of this species has not been formally quantified but is described as common by Eaton et al. (2021). Juniper and Parr (1998) suspected it to number more than 100,000 individuals and, given the immense size of its range, it may well be many times this. It remains commonly observed in suitable habitat, including isolated blocks of forest in Singapore, but is absent from areas where there is not even scattered native vegetation (eBird 2022). This is congruent with reporting in del Hoyo et al. (1997), which described the species as common in primary habitat and uncommon in secondary habitats and plantations.
Trend justification: The overall population is inferred to be declining in response to habitat loss and degradation, but locally some populations may be increasing.
In the majority of the species' range, the widespread conversion of native forest into plantations is thought to be causing a decline. Although Psittinus cyanurus readily feeds in these plantations and is tolerant of degradation (Juniper and Parr 1998, Peh et al. 2006, Eaton et al. 2021), it is thought to require nearby forest for breeding (del Hoyo et al. 1997), and citizen science data (eBird 2022) support this. In the 10 years to 2022, forest cover in its range reduced by 17-22% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and this is thought to have caused concomitant declines of 15-25%. Additionally, the species may be impacted by trapping for the pet trade (Symes et al. 2018), although no robust data exist to quantify this. In Singapore, where forest cover is stable, the population was reportedly increasing, or at least remaining stable (Lim and Yong 2011).
Combining these threats, the species is suspected to have declined globally by 15-29% over the past ten years, and the same rate is thought likely to occur in the future. This is congruent with Symes et al. (2018), who predicted the species had declined by 27% over 11.4 years to 2018 (adjusted to c.23-24% over ten years), although the latter authors considered trapping to be causing a greater contribution to this than habitat loss.
