Population justification: The population was previously (in 2003) estimated preliminarily to fall in the band 2,500-9,999 mature individuals, however no species-specific density is known, and the species is now known to be considerably more widespread than formerly thought. It is described as locally common (Berryman and Eaton 2020, Eaton et al. 2021) and four birds heard calling along a 1-km transect on a forest track in the Mekongga mountains in south-east Sulawesi indicate the species may, at least locally, be capable of occurring at a relatively high density (A. Berryman in litt. 2021). Consequently, although the population is unknown, it is not suspected to approach the thresholds for listing as threatened.

Trend justification: Given this species' occurrence in montane forests, encroachment by agriculture and timber extraction has been minimal in its range. Global Forest Watch (2021) data, using Hansen et al. (2013) methods and data disclosed therein, suggest that forest loss in its range has been minimal (c.2.5% over three generations: 12.7 years, Bird et al. 2020) and is not necessarily above the rate of natural flux. The population is therefore suspected to be stable, but may decline if forest loss begins to encroach on higher elevation forest.
