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 population trend is difficult to determine. The species is able to thrive in secondary and disturbed habitats (del Hoyo et al. 2004); therefore it is tentatively assessed as being stable.
