This species is known from a number of localities in the eastern mountains of Papua New Guinea, and it is probably widespread in suitable habitats in the region. It occurs at 1,200-1,800m asl and is likely to be restricted by the availability of suitable habitat.
Habitat and Ecology
It is not found in forest, but lives in deep, permanent swamps in grasslands, and in gardens in and near the swamps in which it breeds.
It is common, but occurs very patchily.
There are few current threats, but it could potentially be at risk from drainage of swamps for agricultural use in the future.
The distribution and population status of this species need to be better documented. It has not been found in any protected areas.
