Population justification: Described as scarce and local (Allen 2020). The population size of this species has not previously been estimated formally. In its range approximately 650 km2 of forest remains (at 700-2,000 m elevation), although only 270 km2 of this is at its favoured elevation (<1,000 m) (data from Jung et al. [2020], analysed using sRedList [2023]). On Mt Halcon it evidently remains quite common, with up to 25 being observed in a single day (eBird 2024) but in other forests, including some at suitable altitude, scant survey effort has found it to be comparatively scarce (Dutson et al. 1992, eBird 2024). In the absence of any other data, a precautionary population size of 800-3,000 mature individuals is suspected, although this represents little more than an arbitrary range based on plausible densities generated from survey effort and the density of congeners.

Trend justification: The only plausible threats to this species are habitat loss and degradation, and hunting. Remote sensing data over the past three generations (21 years: 2002-2023) indicate almost no loss (<1%) in the extent of closed-canopy forest within its range; indeed, in this time period there has been a slight increase in canopy extent of c.3%, although this is unlikely to have increased the species' abundance (Jung et al. 2020, and Global Forest Watch 2024 based on data from Hansen et al. [2013] and methods therein). Moreover, forest in its range looks to be intact with little evidence of degradation (Grantham et al. 2020). Consequently habitat loss and degradation are not thought to be causing any declines in this species presently. Hunting is an entirely unknown and unquantified threat, although it is noted that visits to suitable habitat in 1991 (Dutson et al. 1992) and 2015 (eBird 2024) appeared to find it similarly common. Given uncertainty on the extent and acuity of hunting as a threat, the overall global trend of this species is considered Unknown, although it is probably unlikely to be declining rapidly.
