Justification 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). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, 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.

Range & population This species is endemic to the Foya Mountains north of the Idenburg River in northern Irian Jaya, Indonesia.

Ecology: The species occurs between 1,000 and 2,000 m (Diamond 1982, Beehler et al. 1986, Stattersfield et al. 1998).

Threats The Foya Mountains are uninhabited, and with no record of any human encroachment before 1979 (Diamond 1982, Diamond 1985), they are presumed to be largely secure. In addition, they are entirely encompassed within the huge (10,000 km2) Foya Nature Reserve (Sujatnika et al. 1995).
