White-eared Hummingbird

Distribution / Range

The White-eared Hummingbirds have a wide range that includes Canada, United States, Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Belize and Costa Rica.

They breed in southeastern Arizona (Huachuca Mountains: Miller Canyon, Ramsey Canyon - stray to White Mountains, the Mogollon Rim, and the Madrean sky islands), western and southwestern New Mexico, and west Texas in the USA ; Sierra Madre Oriental (northwestern Mexico), Sierra Madre Occidental (western Mexico), Cordillera Neovolcanica (a mountain range across central Mexico), southern Mexico to southern Nicaragua.

White-eared Hummingbirds occurred as vagrants eastward to Mississippi and Michigan. They could conceivably have reached Massachusetts as well.

Resident (non-migratory) populations exist in central Sonora (a state located in northwest Mexico) south to southern Central America.
