Population justification: The global population size has not been quantified.

Trend justification: There are no data on the population trend, but declines are suspected owing to ongoing habitat destruction and degradation (del Hoyo et al. 2003).Within the range, 6% of tree cover has been lost over the past ten years; this has been accelerating to a rate equivalent to 8% over ten years since 2017 (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). These values refer to tree cover loss alone and do not account for forest degradation and fragmentation; consequently, the overall rate of habitat loss is likely higher. A projection of deforestation and habitat loss based on several predictor values found a similar pattern of accelerating habitat loss between 2015 and 2040, to a rate equivalent to 31% over ten years (Negret et al. 2021).
The species has specialised habitat requirements and is considered highly susceptible to forest loss and degradation. Therefore, while the rate of decline has not been quantified and there is considerable uncertainty about the overall rate of habitat loss across the range, declines are here tentatively placed in the band 20-29% over ten years.
