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

Trend justification: The species is undergoing a small decline (Partners in Flight 2019). Although it is generally common, it is negatively affected by the siltation of watercourses in some areas (del Hoyo et al. 2004).
