This species is known only from two islands in the D'Entrecasteaux Islands, Papua New Guinea: the eastern slopes of Goodenough Island, at 1,600m asl, and from 980-1,830m asl on Fergusson Island.
Habitat and Ecology
This species is found in trees and on the ground in open lower montane tropical rainforest and lowland hill forest, as well as in bamboo groves. It is not known whether or not it can tolerate secondary habitats, since it occurs above the altitude at which rural gardening takes place. It is a direct developer and egg clutches have been observed in the hollowed centres of standing, dead bamboo stems.
It appears to be very common, at least on Fergusson Island.
No threats are known at the higher elevations where the species occurs. The habitat on Goodenough Island is heavily impacted by gardening and fires, as well as expanding human populations, up to 300m asl, but is still intact at higher altitudes. On Fergusson Island, the habitat is impacted by gardening up to 300-400m asl in the east, and up to 700m asl in the west.
The species' distribution on nearby islands needs to be documented and an assessment of the population status at the type locality is needed. Its range probably includes Oia Mada Wara Wildlife Management Area.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although its Extent of Occurrence is much less than 5,000 km2, it is common and occurs in habitats that are not under significant threat.
