The guanacaste hummingbird or Alfero's hummingbird [2] (Amazilia alfaroana) is a possible species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica. 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. [3] It is possibly extinct, but the stability of the area where the specimen was found indicates a possible undiscovered population still existing. [4] The IUCN classifies it as critically endangered. [5]
