Population justification: Population size not estimated, but abundance and density evidently varies across its relatively large range. Described as scarce by Allen (2020) and pattern of records eBird 2024) generally suggest that it is commoner in southern parts of its range. Interpretations of its abundance are also obfuscated by the species' generally elusive ecology, with Allen (2020) concluding that it 'may be more widespread than records suggest'.

Trend justification: No monitoring data from which to derive trends, but assumed to be declining moderately rapidly in response to forest cover loss within its range. This species is confined to lowland forest and second growth, much of which has been cleared in the Philippines. Records remain from a scattering of localities (mostly in Mindanao) but it is evidently absent from a range of sites which might otherwise be expected to host it. Within its elevational range, forest cover loss was c.20% in the three generations (12.3 years) to 2023 (Global Forest Watch 2024, based on data from Hansen et al. [2013] and methods therein) but this possibly underestimates the rate of decline in this species. First, it does not take into account selective logging and degradation which is widespread in the Philippines (Grantham et al. 2020). Second, it appears to overestimate the area of existing habitat (confusing some plantations and heavily degraded forests for forest cover), thus underestimated the percentage of decline in habitat. Moreover, sites from where most records of this species come (e.g. PICOP, Brgy Kuden and Samar Natural Park) are being cleared and degraded very rapidly, while sites such as Subic Bay (Luzon) appear to show a declining reporting rate, despite little to no change in forest extent. Overall, it is therefore considered possible that this species may be declining relatively rapidly, equivalent to 20-39% over the past three generations, with similar rates suspected in the future.
