Brilliantly-colored hummingbird with dark tail and mostly red bill. Primarily a Mexican species, but occurs locally in the southwestern U.S. Can appear all dark at a distance, but in the right light, look for beautiful iridescent blues and greens on male's body. Females are less colorful than males, dusky grayish below with prominent white stripe behind the eye. Compare especially with female White-eared Hummingbird, which is more spotted below and has a broader white eyestripe and darker cheek. Occurs in scrubby riparian woodland, canyons, and thorn forest. Often visits hummingbird feeders.
