Population justification: The global population size has not been quantified, but the species is described as usually scarce, although locally common (del Hoyo et al. 2004). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
