Assessment Information [top]

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

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species is found at elevations up to 900 m (Ridgely and Tudor 1994, Stotz et al. 1996) in a wide variety of habitats, including forest edge, plantations, gardens, low restinga and degraded second growth (R. Parrini and J. Minns in litt. 1999), mostly in foothills (Ridgely and Tudor 1994).
Systems: Terrestrial

Threats [top]

Major Threat(s): Agricultural conversion and deforestation for mining and plantation production historically threatened its lowland forests; current threats are urbanization, industrialization, agricultural expansion, colonization and associated road-building (Dinerstein et al. 1995, Fearnside 1996).
