This species is suspected to be declining within its small range. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened. If it is found to be declining moderately rapidly, the species may qualify for uplisting to Vulnerable.

Previously published Red List assessments:
2008 Near Threatened (NT)
2004 Near Threatened (NT)
2000 Lower Risk/near threatened (LR/nt)
1994 Lower Risk/near threatened (LR/nt)
1988 Near Threatened (NT)

Population [top]

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

Trend Justification:  The population is suspected to be in decline owing to ongoing habitat degradation.

Habitat and Ecology [top]

Habitat and Ecology: It is fairly common in the lower and middle growth of montane humid forest and forest edge at elevations of 850-1,400 m (Ridgely and Tudor 1994, Stattersfield et al. 1998).

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 3.6
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Although there is still extensive forest cover in parts of its limited range, deforestation has been severe around Caracas, and many other areas have also been degraded (Huber and Alarcón 1988, Stattersfield et al. 1998).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It occurs in San Esteban, Henri Pittier, Macarao, El Avila and Guatopo National Parks, Pico Codazzi Nature Monument and several other protected areas.

Conservation Actions Proposed
Effectively protect areas where the species occurs. Study its ecology and its ability to persist in degraded and fragmented habitats. Use GIS habitat loss data to produce estimate of declines.
