Population justification: The global population is estimated to number fewer than 50,000 mature individuals (Partners in Flight 2019); thus it is here placed in the band 20,000-49,999 mature individuals. The species is described as 'common' (Stotz et al. 1996).
Trend justification: The population is undergoing a small decline (Partners in Flight 2019).
