This species is thought to have a moderately small range and population which are decreasing in size owing to habitat loss. It is consequently classified as Near Threatened, but further information on its status may lead to its uplisting to a higher category of threat.

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)

Geographic Range [top]

Range Description: Campylopterus villaviscensio occurs on the east slope of the Andes in Ecuador, at three sites in north-east Peru (San Martín, Amazonas) (Sibley and Monroe 1990, Schulenberg and Awbrey 1997, J. Hornbuckle in litt. 1999) and in southern Colombia (Nariño and Putumayo). It is relatively common but is presumably declining due to habitat loss.

Countries occurrence:
Colombia; Ecuador; Peru
Continuing decline in area of occupancy (AOO): Yes
Extreme fluctuations in area of occupancy (AOO): No
Estimated extent of occurrence (EOO) - km2: 22900
Continuing decline in extent of occurrence (EOO): Yes
Extreme fluctuations in extent of occurrence (EOO): No
Continuing decline in number of locations: Yes
Extreme fluctuations in the number of locations: No
Lower elevation limit (metres): 1050
Upper elevation limit (metres): 1500

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:  This species is suspected to lose 23.7-25.7% of suitable habitat within its distribution over three generations (12 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: Unknown Continuing decline of mature individuals: Yes
Extreme fluctuations: No Population severely fragmented: No
Continuing decline in subpopulations: Unknown
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No

Habitat and Ecology [top]

Habitat and Ecology: It occurs in foothill evergreen and elfin forest, and second-growth woodland at 1,050-1,500 m (Parker et al. 1996)

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 4.2
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Much of its montane forests are under intense pressure from conversion for agriculture and cattle pasture, mining operations and logging, with widespread destruction of its habitat also caused by peasant farmers, and tea and coffee growers (Dinerstein et al. 1995).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II.

Conservation Actions Proposed
Effectively protect and manage core areas of remaining habitat. Monitor population at strongholds and search for the species in potentially suitable habitat at new sites. Study its ecology and its ability to persist in degraded and fragmented habitats. Attempt to obtain an accurate estimate of its population size and trends. Quantify extent of habitat losses.
