Population justification: The global population is suspected to number 5,000,000-49,999,999 mature individuals (Partners in Flight 2022). The species is described as 'fairly common' (Stotz et al. 1996).

Trend justification:

The population trend has not been investigated. Tree cover within the range is lost at a rate of 5% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is however not restricted to forest; it is commonly found along borders, in secondary growth and in plantations (Hilty 2020). Consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
