This species occurs on Buka and Bougainville Islands, Papua New Guinea, up to 500m asl.
Habitat and Ecology
It inhabits the floor of tropical rainforest, and also degraded habitats, such as rural gardens, forest regrowth, and plantations. It is a species that breeds by direct development and lays its eggs on the ground.
It is a reasonably common species.
The war in Bougainville has probably minimised impacts of logging, but it is doubtful that this species would be adversely affected by logging.
It is not known from any protected areas.
