Population justification: The population size of this species has not been quantified, but it is described as locally common and eBird (2023) indicate that it is often frequently encountered in relatively large numbers throughout its range. Given the area of forest within its range totals c.25,000 km2 (per Global Forest Watch 2023), it is unlikely to have a small population, even if only a small percentage of this is occupied.
Trend justification: The only identified threat to this species is habitat degradation and clearance, which has been minimal in the last ten years. Between 2011 and 2021, forest extent (>50% canopy cover) reduced by only c.2% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein), and there is little indication that this rate will accelerate in the future. Menon et al. (2009) considered that the species might lose 40-50% of habitat to 2055 based on climate change impacts. However, this ecological niche modelling approach does not address uncertainties in the adaptability and plasticity of this species' ecology and it is treated with caution in the absence of monitoring data. In any instance, the overall rate of decline in this species is not thought to exceed 10% over ten years, and is suspected here to be declining at an ongoing rate of 1-9%.
