From the IUCN Red List Species Account:


Range Description

This species has been recorded from localities in central and southern Luzon, Bohol, and Mindanao in the Philippines. It has also been recorded from Samar, Leyte, Polillo, Dinagat and Catanduanes Islands (Philippines Red List Assessment Workshop May 2017). It probably occurs more widely than current records suggest, especially in areas between known sites.

Habitat and Ecology

This species inhabits arboreal microhabitats, usually beside water (streams, ponds, rivers) in undisturbed lower montane and lowland forests. Individuals have been observed among leaves, on leaves of trees and shrubs and procket ferns and on rocks near rivers (Plaza and Sanguila 2015). It builds foam nests on vegetation above stagnant pools of water (Siler et al. 2011).


It is locally common, but patchily distributed. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend


Major Threats

The major threat is the destruction and conversion of both lowland and lower montane rainforest habitat due to small-scale shifting agriculture, large-scale oil palm plantations, expanding human settlements, wood collection for firewood and charcoal production, and illegal logging by commercial entities (Philippines Red List Assessment Workshop May 2017). There is also nickel, chromite, and gold mining, and limestone and marble quarrying in eastern Mindanao. In addition, the quality of its stream habitat is subject to pollution due to agricultural effluents, soil erosion, and mine-tailings (Philippines Red List Assessment Workshop May 2017).

Conservation Actions

Conservation Actions
This species range includes a few protected areas, including Pasonanca Natural Park (Luzon), Mount Malindang National Park and Mount Apo Natural Park. 

Conservation Needed
There is a need for improved protection of remaining tracts of intact lowland and montane rainforest in the islands where this species occurs.

Research Needed
Further research on this species' distribution, population size and trends is recommended.

Red List Status

Vulnerable (VU)


Listed as Least Concern in view of its wide distribution and presumed large population.

Taxonomic Notes

This may be a complex of several cryptic species (Philippines Red List Assessment Workshop May 2017).
