Population justification: The population size of this taxon has not been quantified, but it is described as uncommon (Eaton et al. 2021). In recent surveys on Peleng by Burung Indonesia, this species was found at only five sites (of eleven surveyed) and was absent from highly disturbed agricultural/scrubby landscapes (J. S. Udin in litt. 2023); nonetheless, within its total range lies approximately 4,500 km² of forest at a suitable elevation, thus even if only a relatively small proportion of this is occupied, the total population size is probably not very small.

Trend justification: The only identified threat to this species is habitat loss and degradation, particularly caused by slash and burn agriculture. Because this species is absent from agricultural areas (which it presumably once formerly occupied when forested), a continuing decline caused by habitat loss is inferred. No direct data are available to estimate the rate of decline, however in the 11 years to 2022, forest cover in the species' range declined by c. 7% (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). Its exact habitat tolerances are poorly known, but it is at least somewhat forest dependent (del Hoyo et al. 2020, J. S. Udin in litt. 2023) and rates of forest loss are considered a reasonable proxy for population reduction; accordingly it is suspected of declining at an ongoing rate of 5-15% over three generations.
