Population justification: The global population size has not been quantified, but it is believed to be large as the species is described as common in at least parts of its range (Hall and Moreau 1970, Roberts 1993, Zimmerman et al. 1996, Borrow and Demey 2001, Stevenson and Fanshawe 2002). The subspecies modestus (previously recognised as a separate species), was considered Near Threatened, although its population size is unknown numbers are assumed to be small.

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