Justification This scarce and poorly known species has a highly restricted range, and is likely to have a moderately small global population size. Habitat loss is suspected to be causing slight population declines in parts of the range. It is therefore currently considered Near Threatened.

Range & population Oriolus hosii is apparently endemic to Sarawak, Malaysia, where it is restricted to montane forest at 900-2,000 m, with records from Murud, Derian, Dulit, Batu Patap, Mt Kalulong and Mt Mulu. It is rarely recorded and little known.

Ecology: This species is apparently restricted to mossy transitional forest around 1,100-1,200 m on the sandy north side of the Dulit range.

Threats Habitat clearance through logging and agricultural development is now encroaching into montane areas within the range.

Conservation measures proposed Conduct repeated surveys within the range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Protect significant areas of suitable forest, in both strictly protected areas and community-led multiple use areas.
