Population justification: The global population size has not been quantified, but the species is reported to be uncommon in most of its range. However it is reported to be locally common in places (del Hoyo et al. 1997).
Trend justification:
The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016).
