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 'fairly common but patchily distributed' (Stotz et al. 1996).

Trend justification: The population is undergoing a small decline (Partners in Flight 2019), which is thought to be caused by intense persecution for the cagebird trade in parts of its range.
