Population justification: The global population size has not been quantified, but this species is described as 'fairly common but patchily distributed' (Stotz et al. 1996).
Trend justification: Slow to moderate declines are suspected to be occurring, owing to on-going habitat loss, as well as persecution in the wild bird trade.
