Justification of Red List Category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The global population size has not been quantified, but the species is described as common in many areas (del Hoyo et al. 2001).
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)
