Synonyms

Amazilia alfaroana

The Guanacaste hummingbird, also known as the Alfaro's hummingbird or Miravalles hummingbird[2] (Saucerottia alfaroana), is a possibly extinct species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica.

## Taxonomy

[edit]

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

[edit]

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.[1]
