Population justification: The global population is estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019). The species is described as 'common' (Stotz et al. 1996).

Trend justification: The species is tolerant of moderate levels of habitat disturbance (del Hoyo et al. 2003). Therefore, in the absence of evidence for any declines or substantial threats, the population is assessed as being stable.
