This species is found in the Sierra Madres, on north-eastern Luzon Island in the Philippines in Cagayan, Isabela, and Aurora Provinces. It has been recorded from sea level to 400 m asl. Its extent of occurrence (EOO) is 18,130 km2 and all individuals are considered to occur in one threat-defined location.
Habitat and Ecology
This species inhabits the forest floor stratum in lowland forests, breeding takes place by direct development and it makes its nests in leaf litter.
Intensive surveys took place during 2004-2006 which confirmed that the population is dense and common across its range, typical of the pattern of forest-obligate species in Philippines (Philippines Red List Assessment Workshop May 2017). Surveys during 2011-2013 also recorded the species within its known range (Philippines Red List Assessment Workshop May 2017). Prior to these surveys, the species was known only from the type locality (Palanan), Isabela Province.
The major threat is habitat loss due to small-scale shifting agriculture, expanding human settlements, wood collection for firewood and charcoal production, and illegal logging by commercial entities (Philippines Red List Assessment Workshop May 2017). In addition, the construction of a major east-west road was completed in 2016 through the western part of Isabela Province and the presence of the road is anticipated to intensify illegal logging activities (Philippines Red List Assessment Workshop May 2017).
This species range includes a few vast protected areas in the Sierra Madres. Since the 2004 assessment, in collaboration with various regional academic institutions, NGO-led awareness campaigns have been taking place to educate the public regarding the need to protect remaining forests on Luzon Island, resulting in positive responses by local communities and improved protection for priority species.
Enforcement of protected area boundaries and appropriate management practices are required to safeguard the remaining habitat, as well as ongoing awareness campaigns to raise public support.
Further work is required to improve the understanding of the species' population size, distribution, and trends.
Red List Status
Listed as Vulnerable because its extent of occurrence (EOO) is 18,130 km2, all individuals are in a single threat-defined locations, and there is continuing decline in the extent and quality of its habitat on Luzon in the Philippines.
