Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Ekstrom, J., Butchart, S., Benstead, P., Harding, M.
Justification:
Although this species may have a restricted range, it is not believed to 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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 [top]

Population: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species is fairly common on the edge of elfin forest and in semihumid/humid montane scrub, preferring areas such as clearings and treefalls with scattered, very dense vegetation, at elevations of 1,280-1,800 m (Stotz et al. 1996, Cleere and Nurney 1998).
Systems: Terrestrial

Threats [top]

Major Threat(s): The tepuis are largely inaccessible and remain relatively undisturbed (Huber and Alarcón 1988). However, many of the endemic plants of the tepuis harbour flammable secondary compounds which help to spread fire and this could affect available habitat. Any such habitat loss would be absolute as montane forests on the tepuis tend not to regrow but are replaced by bracken Pteridium (Stattersfield et al. 1998).
