Talamanca Hummingbird does not have an IUCN Red List conservation ranking, as it is considered by IUCN to be a subspecies of Rivoli's Hummingbird (Eugenes fulgens) (BirdLife International 2017); the combined (and much more broadly distributed) species is rated as Least Concern. The relative abundance of Talamanca Hummingbird is rated as "fairly common" in both Costa Rica and in Panama (Ridgely and Gywnne 1989, Stiles and Skutch 1989). Eugenes is included in Appendix II of CITES, however, as is the case with all hummingbirds, regardless of rarity (except for Hook-billed Hermit Glaucis dohrnii, which is Endangered and is on Appendix I of CITES).

Talamanca Hummingbird potentially is vulnerable to habitat loss and degradation, although ample forest remains in the Cordillera de Talamanca.
