|Scientific Name:||Eriocnemis isabellae|

|Taxonomic Source(s):||del Hoyo, J., Collar, N.J., Christie, D.A., Elliott, A. and Fishpool, L.D.C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Lynx Edicions BirdLife International.|
|Identification information:||The male is blackish-green, with iridescent blue-green rump and blue-black tail, bluish-violet undertail, and white leg puffs, and differs from other Eriocnemis in having a bicoloured blue-violet and green gorget. Females are similar to E. nigrivestis and E. vestitus but underparts are more intensively fringed rufous with turquoise reflections on the belly centre (Cortés-Diago et al. 2007).|
|Red List Category & Criteria:||Critically Endangered B1ab(iii)+2ab(iii) ver 3.1|

|Facilitator/Compiler(s):||Sharpe, C J, Symes, A. & Ashpole, J|
This recently described species qualifies as Critically Endangered because it is known from a single location and has an extremely small area of occupancy within which habitat quality is continuing to decline owing to conversion for agriculture (particularly coca cultivation).
|Previously published Red List assessments:|
|Range Description:||Eriocnemis isabellae has been recently described from Cauca Department, south-west Colombia, where it occurs in a tiny area of the Serranía del Pinche (Cortés-Diago et al. 2007). Three birds (one male and two females) were mist-netted in 2005 and a total of six further males were caught in 2006 (Cortés-Diago et al. 2007). The global population has not been quantified but is presumably very small given that the area of suitable habitat is thought to be less than 10 km2, and it is suspected to be decreasing as elfin forest habitat is converted for agriculture and illegal coca plantations.|

|Population:||The population has not been quantified, but it is presumably very small given that the area of suitable habitat is thought to be less than 10 km2.|
Trend Justification: The population is suspected to be decreasing owing to habitat loss and degradation, however the rate of decline has not been quantified.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits the cloud and temperate forest zone, within which the species appears to be associated with elfin forest on steep slopes along mountain ridges (Cortés-Diago et al. 2007). Elfin forest at the type locality averages 6-8 m in height with frequent natural clearings and is found at around 2,600-2,900 m (Cortés-Diago et al. 2007).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||4.2|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The primary threat is the shifting of the agricultural border towards remaining primary forests, causing a loss of vegetation cover, contamination of watersheds and soil degradation (Cortés-Diago et al. 2007). Illegal coca cultivation is a major threat due to the lack of governmental presence, with 8.3 % of potentially suitable habitat reportedly damaged annually by coca cultivation. The potential completion of a road from El Estrecho in the Patía Valley to Guapi on the Pacific coast would hold serious implications for Serraníadel Pinche (Cortés-Diago et al. 2007).|
Conservation Actions Underway
CITES Appendix II. There is an ongoing conservation plan involving local authorities, community leaders, Ministry of Environment, The Hummingbird Conservancy, Ecohabitats foundation and local residents.
Conservation Actions Proposed
Carry out further studies to determine status and population size. Develop a Species Action Plan. Continue and extend local conservation and education initiatives. Work towards the creation of a protected area in the Serraníadel Pinche.
