Population justification: The global population size has not been quantified, but the species is described as generally fairly scarce, although common on Tanahjampea, Tanimbar, Wetar and Karimunjawa islands (Gibbs et al. 2001, Trainor et al. 2009, Susanto 2012, B. van Balen in litt. 2016, C. Trainor & J. P. Lopez in litt. 2020), 'uncommon' on Babar and 'fairly frequent' at secondary forest edges on Sermata (Trainor and Verbelen 2013). Across Timor it appears to have declined sharply due to intensive hunting (C. Trainor & J. P. Lopez in litt. 2020).

In West Timor there are now only very low numbers at Bipolo and Camplong, where previously large flocks could be easily observed. Similarly, in Timor-Leste numbers encountered in Nino Konis Santana National Park in 2019 were far lower than previously, with the decline ascribed to hunting occurring throughout Timor (C. Trainor & J. P. Lopez 2020). The species is now locally absent from many formerly occupied sites in the country, and is even greatly reduced in the Oecusse enclave (C. Trainor & J. P. Lopez in litt. 2020).

Trend justification: Hunting and habitat degradation are suspected to be driving a moderate decline overall, but rapid declines have occurred due solely to hunting in Timor-Leste and West Timor in recent years (C. Trainor & J. P. Lopez in litt. 2020). The species has declined from being common in forested sites (Bipolo and Camplong in West Timor, Nino Konis Santana National Park in Timor-Leste) at the start of the 2000s to only being recording in ones and twos in 2019 (C. Trainor & J. P. Lopez in litt. 2020). Should the impact of hunting be mitigated, there is the potential for considerable future recovery in the depleted parts of the range.

On many of the small islands on which the species occurs numbers remain good. The stronghold of the species may now be Wetar where there continue to be counts of large flocks and a large proportion of forest remains including favoured riparian Canarium groves (Trainor et al. 2009, C. Trainor & J. P. Lopez in litt. 2020).
