Population justification: The global population size has not been quantified, but the species is described as generally fairly scarce, although common on Tanahjampea, Timor, Tanimbar, Wetar and Karimunjawa islands (Gibbs et al. 2001, Trainor et al. 2009, Susanto 2012, B. van Balen in litt. 2016), 'uncommon' on Babar and 'fairly frequent' at secondary forest edges on Sermata (Trainor and Verbelen 2013).

Trend justification: Hunting and habitat degradation are suspected to be driving a moderate decline, with forest loss potential causing more rapid declines in some areas (e.g. Vetter 2009).
