Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2014-07-24
Assessor(s): BirdLife International
Reviewer(s): Butchart, S.
Contributor(s): Navarro, A. & Valdez Gómez, H.
Facilitator/Compiler(s): Benstead, P., Isherwood, I., Sharpe, C J, Symes, A. & Taylor, J.
Justification:
This species has been downlisted from Near Threatened because its range is larger than previously estimated, although its population, which may be moderately small to large, is nevertheless suspected to be in slow to moderate decline owing to on-going habitat loss and degradation. It is listed as Least Concern on the basis that it is not thought to approach the thresholds for Vulnerable under any of the Red List criteria.

History:
2012 Near Threatened

Geographic Range [top]

Range Description: Megascops seductus has a moderately small range in west-central Mexico, where it is a fairly common resident in Jalisco, Colima, Michoacán, Morelas and Guerrero (Howell and Webb 1995a, A. G. Navarro in litt. 1998).

Population [top]

Population: Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band for 20,000-49,999 individuals. This is assumed to equate to c.13,300-32,700 mature individuals. The population density in the Sierra de Huautla Biosphere Reserve was estimated to be 6.7/km2 during the dry season, suggesting that this species is moderately common there (Alba-Zúñiga et al. 2009).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits thorn-forest and arid open to semi-open areas with scattered trees, as well as secondary growth, at elevations of 600-1,500 m (Howell and Webb 1995a, del Hoyo et al. 1999). In a study in Sierra de Huautla Biosphere Reserve, conserved dry forest was the preferred habitat, followed by thorn forest, disturbed forest and agricultural systems, with fewest records in Gliricidia-Caesalpina forest (Alba-Zúñiga et al. 2009). Its diet is little known, but insects and small vertebrates have been recorded (del Hoyo et al. 1999). Breeding has been noted in June (del Hoyo et al. 1999).

Systems: Terrestrial

Threats [top]

Major Threat(s): Available habitat appears to be in decline (del Hoyo et al. 1999). Agriculture is expanding in this species's range, especially for citrus plantations and cattle-ranching (Stattersfield et al. 1998).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II. Although some recent studies have collected data on this species (e.g. Alba-Zúñiga et al. 2009, Nova-Muñoz et al. 2011), further research and conservation actions are hindered by the current security situation in this region of Mexico (H. E. Valdez Gómez in litt. 2013).

Conservation Actions Proposed
Conduct surveys to assess the species's local abundance, distribution and total population size. Research population trends in various parts of its range (Alba-Zúñiga et al. 2009). Monitor population trends through regular surveys. Monitor rates of habitat loss and degradation. Protect areas of suitable habitat. Study the species's ecology.
