Population justification: The global population size has not been quantified. Based on its very small range the population is unlikely to be large; it is here tentatively placed in the band 2,500-9,999 mature individuals, though this number requires confirmation. A precise population estimate is urgently needed.

Trend justification: The population trend has not been assessed directly. Large areas of forests persist within the range and tree cover loss is currently low (2% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species occupies a variety of habitats, including forests, edge and bushy areas (Jaramillo et al. 2020). Therefore, despite the low level of tree cover loss within the range, this is not thought to impact on the population size. In the absence of evidence for any declines or substantial threats, the population is assessed as stable.
