Population justification: The population size of this species has never been quantified. Its relative abundance is hampered by its secretive nature, although knowledge of the call led Diamond and Bishop (2015) to assert that, in the Kumawa Mountains at least, the species is quite common.

Trend justification: The population is precautionarily suspected to be declining because of very local forest degradation impacts and perhaps some localised hunting. Remote sensing data indicate that forest cover loss in the species' range in the three generations (12.9 years; Bird et al. 2020) to 2022 was minimal, equal to only 1-2% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). The rate of decline is not estimated, although is likely to be very slow.
