The Guanacaste hummingbird, also known as the Alfaro's hummingbird or Miravalles hummingbird, is a possibly extinct species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica.
Taxonomy
It is usually treated as a subspecies of the Indigo-capped hummingbird or a hybrid between two unknown hummingbird species, but analysis of the holotype suggests it is its own species. ==Conservation==
Conservation
It is possibly extinct, but the ecological stability of the area where the specimen was found indicates a possible undiscovered population still existing. The IUCN classifies it as critically endangered. == References ==
