Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2013
Date Assessed: 2013-11-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S.
Contributor(s): Fjeldså, J.
Facilitator/Compiler(s): O'Brien, A., Sharpe, C J, Symes, A.
Justification:
This species is believe to have a very small range and is therefore highly susceptible to any future threats to its habitat. It is consequently classified as Near Threatened.

History:
2012 Near Threatened

Geographic Range [top]

Range Description: Megascops marshalli is known from six localities from Pasco department, Peru, south to Cochabamba department, Bolivia (Herzog et al. 2009). It has a disjunct distribution with four subpopulations: from the Cordillera Yanachaga, Pasco (Weske and Terborgh 1981, Fjeldså and Krabbe 1990), south into north-central Junin, Peru; Cordillera Vilcabamba, north-west Cusco and adjacent Junin, Peru which includes the type locality and Campamento Segakiato, the source of a recent specimen; Madidi National Park, La Paz, Bolivia, from Inciensal Sauce west to just across the Peruvian border, Puno; and Cochabamba and immediately adjacent La Paz, encompassing the Cordillera Cocapata, the adjacent unnamed mountain range, and Serranía de Callejas (Herzog et al. 2009). The overall extent of occurrence is calculated as 12,700 km2 (Herzog et al. 2009).

Population [top]

Population: The global population size has not been quantified, but the species is described as locally rather abundant (Konig et al. 1999).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Its preferred habitat is pristine to at most slightly disturbed wet montane forest with high structural complexity, dense understory, and abundant epiphytes. It has been recorded at altitudes of 1,550–2,580 m, but locally its altitudinal range is 500 m (Herzog et al. 2009).

Systems: Terrestrial

Threats [top]

Major Threat(s): The north Cordillera Vilcabamba is the most intact area of montane habitat in Peru (J. Fjeldså verbally 2000), and this sub-population is considered secure. Cloud-forest in the Cordillera Yanachaga was largely undisturbed when the species was recorded, but threats are unquantified and require clarification.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II.

Conservation Actions Proposed
Clarify extent of threat to cloud-forest in the Cordillera Yanachaga. Survey ridges in the Gran Pajonal area. Protect areas of suitable habitat and safeguard against future threats. Estimate population size (Herzog et al. 2009). Quantify deforestation rates within the species' range (Herzog et al. 2009).
