Lucifer Hummingbird

The Lucifer Hummingbird (Calothorax lucifer), historically referred to as the Lucifer Sheartail, is a captivating desert specialist of the southwestern United States and Mexico. Known for its dramatically curved bill and the male's striking magenta throat, this species thrives in dry, rugged terrains that would challenge other hummingbirds. While they are common residents across the Mexican Plateau, select populations migrate north each spring to breed in the arid canyons of west Texas, southern New Mexico, and southeastern Arizona, making them a highly sought-after prize for North American birdwatchers.

Identifying the Lucifer Hummingbird relies heavily on their unique silhouette and vibrant plumage features.

Key Field Marks

• The Bill: Both sexes possess a long, slender, and distinctly downward-curved (decurved) bill. This is a primary differentiator from most other North American hummingbirds.
• Adult Male: Features an iridescent, deeply flared magenta-purple gorget (throat patch) that extends into elongated feathers at the sides. They have a brilliant green back, whitish chest, and a deeply forked, dark, narrow tail.
• Adult Female: Lacks the brilliant gorget, showing a pale buff-colored throat and underparts instead. The female's tail is rounded (unlike the male's deeply forked tail) and features white outer tips.

Similar Species

• Costa's Hummingbird: Also has a flared purple gorget, but its bill is straight, its crown is also purple (unlike the green crown of the Lucifer), and its tail is much shorter and not deeply forked.
• Black-chinned Hummingbird: Females can look similar, but Black-chinned females have a straight bill and lack the rich buffy throat and breast wash of the female Lucifer.

Lucifer Hummingbirds are specialized inhabitants of arid and semi-arid landscapes.

Habitat Preferred

They are primarily found in dry desert scrub, rocky canyons, and steep hillsides dominated by desert vegetation like agave, ocotillo, cholla, and desert willow. They are especially tied to Chihuahuan Desert habitats.

Range and Migration

• Breeding Range: Central and northern Mexico, extending into the bootheel of New Mexico, southeastern Arizona (primarily the Portal area), and western Texas (especially Big Bend National Park).
• Wintering Range: They migrate south to spend the winter in central and southern Mexico.
• Migration Timing: Arrive in the southwestern US in late March or April, and depart by September or October.

Diet and Feeding

Their diet revolves around floral nectar and small insects. They are crucial pollinators for several desert plants, especially Havard's agave (Agave havardiana). They also capture small insects mid-air (hawking) or glean them from foliage to obtain necessary protein.

Breeding and Nesting

Females construct small cup nests made of plant down, spider webs, and lichen, typically placed on thorny shrubs, cacti, or directly on steep canyon rock faces. They lay a clutch of two tiny white eggs.

Courtship and Vocalizations

• Courtship Display: The male performs a dramatic 'shuttle' display. He flies back and forth in front of a perched female, flaring his magenta gorget, followed by a steep vertical dive accompanied by a sharp, mechanical snapping sound produced by his outer tail feathers.
• Vocalizations: Their call is a dry, rapid chipping, often heard when defending feeding territories. Their wings also produce a distinctive dry, high-pitched whirring sound during flight.
