Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species has a small range which is suspected to be decreasing owing to habitat loss and a moderately small, declining population. However, this is not yet severely fragmented or restricted to few locations. The species is consequently classified as Near Threatened.

Geographic Range [top]

Range Description: Megascops colombianus is known from the Pacific slope of the West Andes in Colombia and north-west Ecuador (Chocó to Cotapaxi) ( Fitzpatrick and O'Neill 1986, Fjeldså and Krabbe 1990, Sibley and Monroe 1990, Parker et al. 1996, Freile and Chaves 1999). It is common at La Planada Nature Reserve (Salaman 1994), but is usually considered uncommon (Ridgely et al. 1998).

Population [top]

Population: The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to 6,700 mature individuals. This requires confirmation.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It was thought to inhabit montane evergreen forest, but apparently occurs in tall secondary forest, forest edge and open pasture, at 1,250-2,200 m (Parker et al. 1996, Freile and Chaves 1999). Its overall dependence on forest within its life-cycle is unknown.

Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation is accelerating within its range, primarily owing to intensive logging, human settlement, cattle-grazing, coca cultivation and gold-mining (Salaman 1994, Dinerstein et al. 1995, Salaman and Stiles 1996). 

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II. It occurs in a number of small protected areas, and probably in Munchique National Park, Cauca, Colombia and Cotacachi-Cayapas Ecological Reserve, Esmeraldas, Ecuador (Salaman 1994, Freile and Chaves 1999).

Conservation Actions Proposed
Clarify its ecological and habitat requirements, particularly its dependence on forest. Clarify its presence in Munchique National Park and Cotacachi-Cayapas Ecological Reserve, and search in other potentially suitable areas. Effectively protect core areas of remaining suitable habitat
