Population justification: The population size of this species is unknown. Within its mapped range, there was approximately 24,000 km2 of forest in 2015, but a large proportion of this was degraded, and only 7,800 km2 of closed-canopy forest, from which most observations are made (eBird 2023), remained at that time (NAMRIA 2023). While habitat loss has reduced this since 2015 (Global Forest Watch 2023) and only a proportion of this area is likely to be occupied, the population probably still numbers tens of thousands of individuals.
Trend justification: Suspected to be declining because of forest loss and degradation. No population data for this forest-dependent species are available and remote sensed forest cover data are used as a proxy to predict rates of decline. In the past three generations (13 years: 2010–2023), forest extent in its mapped range was reduced by c. 6.5% (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). However, there are two factors to consider when interpreting the extent to which this value reflects population reduction. First, it does not account for forest degradation and the remote sensing data used are relatively insensitive to, for example, selective logging. The extent to which this species is impacted by forest degradation is poorly known; while it has on occasion been found in disturbed forest (Collar et al. 1999, Allen 2020), the majority of available records (eBird 2023) are from closed-canopy forest and it is likely that forest degradation is causing additive declines in places. The second thing to consider is that the species' mapped range contains areas down to 100–200 m (based on extreme records made at these elevations). At low elevations A. hombroni is evidently scarce, and is commonest above 1,000 m, where forest loss on Mindanao over the past three generations has been much lower (approximately 1–3%). The method used to derive the value of 6.5% therefore has the potential to have both under- and overestimated population declines. To account for these uncertainties, the population is suspected of having declined by 1–15% over the past three generations; in the absence of data to suggest otherwise, the same rate of reduction is suspected to occur in the next three generations (13 years: 2023–2036), although rates could slow with an increasing proportion of birds in more secure, montane forests.
