Justification: 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). |

Geographic Range [top]
| Range Description: | Eriocnemis isabellae has been recently described from Cauca Department, south-west Colombia, where it occurs in a tiny area of the Serraníadel Pinche1. Three birds (one male and two females) were mist-netted in 2005 and a total of six further males were caught in 20061. 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. |

Habitat and Ecology [top]
| 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 ridges1. 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 m1. |

Threats [top]
| 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 degradation1. 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 PatíaValley to Guapi on the Pacific coast would hold serious implications for Serraníadel Pinche1. |
Conservation Actions [top]
| Conservation Actions: |
Conservation Actions Underway 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. |
