(Underwood, 1896)

The guanacaste hummingbird or Alfero's hummingbird[2] (Amazilia alfaroana) 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.[3]

## Conservation

It is possibly extinct, but the ecological 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]
