This endemic is known only from western Sabah, in Borneo, Malaysia, at elevations of 750-1,800m asl.
Habitat and Ecology
It has been found in primary and selectively logged forests, where it calls from shrubs and small trees 2-4m above the ground. Breeding takes place by direct development.
It is locally abundant in suitable habitat.
The major threat is habitat loss in lowland areas due to clear-cutting, and the forests at one locality, Mount Trus Madi, have already been severely damaged.
It is present in Gunung Kinabalu National Park and the Crocker Range. Strengthened and expanded protection of submontane and montane forests is essential for the long-term survival of this species.
Red List Status
Listed as Endangered because its Area of Occupancy is probably less than 500km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
