Also known as the blue-capped hummingbird, it is restricted to a small area of the Sierra Madre del Sur in Oaxaca, Mexico. It often uses traditional shade coffee plantations, making sustainable coffee farming an important conservation ally. Habitat loss and fragmentation are the main threats, and protecting humid montane forests is critical for its survival.
