Population justification: The global population size has not been quantified, but the species is described as common to abundant. The population on Yap has not been quantified but the species's population in the rest of its range is estimated to be 83,500 individuals (del Hoyo et al. 1999).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
