Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AVES PASSERIFORMES PITYRIASEIDAE

Scientific Name: Pityriasis gymnocephala
Species Authority: Temminck, 1835
Common Name(s):
English Bornean Bristlehead

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Benstead, P., Gilroy, J., Taylor, J.
Justification:
This unusual species is likely to be declining moderately rapidly throughout much of its range as a result of forest loss and degradation. It is currently considered Near Threatened, and should be carefully monitored.

Geographic Range [top]

Range Description: Pityriasis gymnocephala is restricted to Borneo, where it occurs patchily in lowland forests of Sabah and Sarawak, East Malaysia, Brunei and Kalimantan, Indonesia (BirdLife International 2001).

Population [top]

Population: The population size of this species has not been quantified, but it is described as uncommon.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is found principally in peatswamp forest, but is also recorded from primary evergreen forest, logged forest and tall secondary forest up to 1,000 m. It is a noisy and social species, moving in small groups through the canopy and feeding on invertebrates, small reptiles and amphibians.

Systems: Terrestrial

Threats [top]

Major Threat(s): Rates of forest loss in the lowlands of Borneo have been rapid, particularly in Kalimantan, where the forests have suffered a recent escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect (particularly in 1997-1998), with peatswap forests being particularly affected. The magnitude of these threats may be allayed by this species's tolerance of logged, secondary and hill forest, although more research is required to determine the full habitat requirements of this unique species.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species, although it occurs in a number of protected areas.

Conservation Actions Proposed
Conduct repeated surveys in areas within and surrounding the species's range to measure rates of population decline or range contraction. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Campaign for the protection of remaining tracts of peatswamp forest on Borneo.
