This species has been uplisted to Vulnerable because its range (extent of occurrence - EOO) has been more accurately calculated using new field data (Eisermann 2011); the bird is now known to have a small (9,780 km2) range, within which its pine-oak montane forest habitat is rapidly disappearing (Cayuela et al. 2006). As a consequence, its EOO, area of occupancy (AOO) and quality of habitat are inferred to be declining, and its habitat is now highly fragmented (Eisermann 2011). It is thus considered Vulnerable.
|Previously published Red List assessments:||
Megascops barbarus is endemic to the highlands of Chiapas, south-east Mexico, and west Guatemala (Howell and Webb 1995a, del Hoyo et al. 1999).

|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 20,000-49,999 individuals here.
Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction. Montane forests in Chiapas have been reduced to less than 25% of their original area with an annual deforestation rate of at least 2.7% over the last 30 years (Cayuela et al. 2006).
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is found in montane evergreen and humid pine-oak forest at elevations of 1,800-2,500 m (Howell and Webb 1995a). In Guatemala is also occurs in ten year old pine plantations (Eisermann 2011). Its diet consists mainly of large insects, particularly beetles, which are captured in the understorey by a sit-and-wait strategy (Enríquez & Cheng 2008). Breeding likely takes place between March and June (Enríquez & Cheng 2008). The only known nest was found in June 2001 2.45 m above ground in a natural cavity of a large living oak Quercus laurina; inside was an adult red-morph female brooding a single grey-morph nestling estimated to be 3 weeks old (Enríquez & Cheng 2008). Birds moult in the rainy season, from July to October (Enríquez & Cheng 2008).
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||7|
|Movement patterns:||Not a Migrant|
Pine-oak forest is disappearing rapidly through logging for firewood and charcoal, agricultural expansion, urbanization and bark-beetle epidemics that are exacerbated by habitat degradation (Stattersfield et al. 1998, Ochoa-Gaona and González-Espinosa 2000). Civil war in Chiapas, Mexico, accelerated deforestation (P. J. Bubb in litt. 1997).
Conservation Actions Underway
CITES Appendix II. No other targeted conservation action is known for this species. Conservation Actions Proposed
Carry out surveys to assess the species's population size. Monitor population trends through regular surveys. Monitor rates of habitat loss and degradation. Study the species's ecology (del Hoyo et al. 1999). Protect suitable habitat. Future research should focus on the breeding ecology, life history strategies, demography, and population trends to evaluate the conservation status of this species; this work will be essential for a better understanding of how habitat degradation may be
affecting this species’ survival (Enríquez & Cheng 2008).
