Population justification: The global population size has not been quantified, but the species is described as common in many areas (del Hoyo et al. 2001).

Trend justification: The population is suspected to be declining locally owing to ongoing habitat destruction (del Hoyo et al. 2001, but an analysis of the impacts of deforestation on endemic birds in New Britain suggests that rates of forest loss within this species’s elevation range are unlikely to cause a population decline that approaches 30% over three generations (c.13 years)
