Palawan Striped-babbler Stachyris hypogrammica

Justification
This species has a highly restricted range, although it remains relatively common within occupied sites. Its montane habitats are relatively safe from the threat of conversion at present, but the situation should be monitored carefully. It is currently listed as Near Threatened.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Stachyris hypogrammica is endemic to Palawan, Philippines, where it is known from Mt Victoria, Mt Mataling, Mt Borangbato, Mt Mantalingajan (at the peak) and at Magtaguimbong, although it is expected to occur in other areas of suitable habitat within its elevational range (R. Hutchinson in litt. 2013). Various reports have suggested that it remains common within its limited distribution.

Population justification
The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2007).

Trend justification
Data on trends are unavailable, but populations are suspected to be stable as key habitats remain intact.

Ecology
This species occurs in primary montane forest above 1,000 m in the south of the island. Observations on Mount Mantalingahan and Mount Victoria suggest it is not uncommon above 1,300 m (R. Hutchinson in litt. 2013).


Threats
The montane habitats occupied by this species appear to remain relatively secure and are unlikely to be at imminent threat from logging, conversion and development (Collar et al. 1999, R. Hutchinson in litt. 2013), although rates of deforestation in general are increasing on Palawan.


Conservation Actions Underway
No targeted conservation actions are known for this species.

Conservation Actions Proposed
Monitor populations at known sites and survey surrounding suitable areas to determine the full extent of the species's range. Monitor rates of habitat conversion within the altitudinal limits of the species. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
