In the Ecuadorian Andes, the Black-breasted puffleg (Eriocnemis nigrivestis), a tiny hummingbird measuring just 9 centimetres, is clinging to survival within its last sanctuary, the Yanacocha Reserve. This ancient forest, established 25 years ago by the Jocotoco Foundation, has become a vital centrepiece for Andean biodiversity.
The International Union for Conservation of Nature reports that the global population of this emblematic bird, which is native to Quito, has plummeted to a critical 150 to 200 individuals. The bird is easily identified by the striking white “trousers” of feathers around its legs, contrasting with its deep, metallic black chest and bronze-green wings.
“We realised we were conserving an entire ecosystem, not just one species,” conservationist Paola Villalba told The Associated Press. Despite its beauty, the puffleg’s survival is threatened as high-altitude forests are cleared for grazing and agriculture.
Shirley Farinango, of the Birds and Conservation Foundation, noted that the pressure is most intense because the puffleg occupies a narrow ecological niche between 3,000 and 3,500 metres above sea level. This specific elevation, she said, is “prime territory” to be converted to agricultural land.
On the slopes of the Pichincha volcano, 45 kilometres northwest of Quito, conservationists are now racing to restore this cloud-shrouded forest. For the “smallest fairies” of the Andes, these dense trees are more than just a habitat — they are their last stand.
