Population justification: The global population size has not been quantified, but the species has been described as common in logged and unlogged forest edges throughout its range (F. Lambert in litt. 2010; D. Edwards in litt. 2020).
Trend justification: The population is suspected to be in moderately rapid decline overall as a result of the widespread wholesale clearance of lowland forests in the species's range. Over the past three generations (11.7 years; Bird et al. 2020), 20% of tree cover within the range has been lost (Global Forest Watch 2021). However, due to its occurrence in secondary and logged forests (del Hoyo et al. 2020), rates of population decline are not thought to be as steep as rates of forest loss, in any case unlikely to exceed 20% over three generations. The population decline is therefore tentatively placed in the band of 10-19% over three generations.
