Taxonomic note

Population justification: The global population size has not been quantified, but this species is described as 'fairly common to abundant over much of range' (del Hoyo et al. 1999).

Trend justification: The population is suspected to be stable in the absence of evidence for any current declines or substantial threats, although there have been historical declines in parts of the range eg. in Vanuatu (del Hoyo et al. 1999).
