Currently, the Berylline Hummingbird has a rating of Least Concern. This is downgraded from a Lowe Risk rating in 2004.
Some sources list them as an accidental species, since its members apparently do not breed regularly in the US.

They are most likely to be seen at hummingbird feeders in wooded mountain canyons, such as Madera Canyon or in the Huachuca or Chiricahua mountains.
