Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022). The species is described as common to very common (Collar 2020).

Trend justification: The population is undergoing a moderate decline (Partners in Flight 2022). Tree cover within the range is lost at a rate of 4% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests the species occupies a variety of habitats, including woodland, scrub and brushland, secondary growth and plantations (Collar 2020) and as such, low levels of tree cover loss may not impact on the population size. In the absence of evidence of substantial threats, the population is suspected to be stable.
