Population justification: The population size of this species has not been estimated. It is described as rather scarce and localised (del Hoyo et al. 2007) and citizen science data (eBird 2023) indicate generally low abundance; however, the area of highly suitable habitat was estimated by Li et al. (2023) to be very large (although with some uncertainty over the accuracy, since the total value exceeded that of the EOO used here), such that even if only a tiny percentage of this area is occupied, the total population size is probably large.
Trend justification: Historically, deforestation and habitat degradation were suspected of causing declines, however there is little evidence to uphold that this is ongoing, nor evidence to suggest that threats are likely to be operating at a scale any larger than negligible. Remote sensing data also indicate very little change in the majority of this species' vast and remote range. In the future, modelling by Li et al. (2023) found that the area of suitable habitat is unlikely to change in response to climate change between now and 2050. Accordingly, in the absence of any known threats the population is suspected to be stable.
