Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species is listed as Near Threatened as, although it remains widespread and fairly common within its range, it is likely to be declining moderately rapidly in line with rapid deforestation rates.

Geographic Range [top]

Range Description: Pycnonotus tympanistrigus is restricted to Sumatra, Indonesia (BirdLife International 2001). In the early 1990s, it was known by few records and appeared to be very local, but it is now known to be relatively common and widespread, albeit still declining because of habitat loss.

Population [top]

Population: The global population size has not been quantified, but the species is described as occurring widely in areas of remaining forest in the Barisan range (del Hoyo et al. 2005).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits hill and lower montane forest at 600-1,400 m.

Systems: Terrestrial

Threats [top]

Major Threat(s): This species is at risk from deforestation in its lower elevation range, as most of its populations occupy areas below 900 m. In the period 1985-1997, Sumatra lost c.29% of its forest cover (Holmes 2002).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.

Conservation Actions Proposed
Conduct repeated surveys within the species's range to determine its 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. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
