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]
