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 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.

Range & population This species is endemic to Bougainville and the small islands of Buka (Papua New Guinea) and the Shortlands (Solomon Islands).

Ecology: The species is found in forest bird up to 1,300 m. It is not known how well it tolerates secondary habitats but it is probably common in degraded forest like the closely-related Chestnut-bellied Monarch M. castaneiventris (Schodde 1977, Coates 1990).

Threats All the lowlands of Bougainville are susceptible to logging when the island opens up to commerce (G. Dutson in litt. 1999).
