Magnificent Hummingbirds

The Magnificent or Refulgent Hummingbirds (Eugenes fulgens) were named for their spectacular iridescent plumage. Until the mid-1980s, they were referred to as Rivoli’s Hummingbirds.

They are the second largest hummingbirds north of Mexico. Only the Blue-throated Hummingbirds are larger.

They occur in mountains from the southwestern United States to western Panama.

These birds are known to be very friendly, often remaining close to humans within their feeding habitat.

Subspecies and Ranges

Magnificent Hummingbirds (Eugenes fulgens fulgens, Swainson, 1827) – Nominate race

  • Found in southwestern USA (mostly southeastern Arizona; to a lesser degree southwestern New Mexico, Colorado, southwestern Texas and Arkansas). Some occur as far west as California and as far east as Alabama and Florida. They range south through most of Mexico to Guatemala, El Salvador, Honduras and northeastern Nicaragua.

Eugenes fulgens spectabilis (Lawrence, 1867) – sometimes separated from the larger nominate race as Rivoli’s Hummingbird, E. spectabilis.

  • Found in the highlands of Costa Rica and western Panama.

Distribution / Range

In the United States, the Magnificent Hummingbirds are found in highest concentrations in southeastern Arizona and southwestern New Mexico. They are only rare vagrants elsewhere in the United States.

Specifically they have been observed in the following U.S. states: Alabama, Arizona, Arkansas, California, Colorado, Georgia, Kansas, Minnesota, Nevada, New Mexico, Texas, Utah and Wyoming.

They breed in mountainous areas in the southwestern United States and winter in Mexico through to western Panama. They are common residents in the higher elevation mountains of Costa Rica.

Their habitat includes humid montane oak forest from about 2000 m (~ 6 560 feet) to the timberline. They are typically found along the edge and in clearings, but also occur on pastures, open woodland, and scrubby areas.

Magnificent Hummingbird (Eugenes fulgens)


Size: Its length ranges from 4.3–5.5 inches (11–14 cm), with an average weight of 0.2–0.3 oz (7–8 g). Their wingspan is about 7.1 inches (18 cm).

Common Physical Traits: The upper plumage is blackish-green. Both sexes look very dark unless the sun catches the iridescence of the plumage. They have a distinctive white spot behind each eye. The black bill is long, thin and slightly curved.

The male can easily be identified by his iridescent bright blue-green gorget (throat patch). His upper plumage is glossy bronze-green above, turning more bronzed towards his tail. He has a green-bronze chest, greyish abdomen and undertail feathers. His head is black, except for the violet crown (top of head) and white stripes behind the eyes. His black tail is forked.

The male’s iridescent crown and throat patch are only visible at certain angles and in bright light; in poor light, he may appear to have a drab, blackish head.

The female’s upper plumage is bronze-green and her under parts a dull grey. She has a grey throat with faint streaking. Her dark rounded tail has greyish-white tips. Like the male, she has white stripes behind the eyes.

Juveniles look like females, except their plumage is duller and more brown.

Similar species: The female resembles the female Blue-throated Hummingbird; except she lacks the large white tail tips and white cheek streak. She can be differentiated from other hummingbird species by her larger size.

Nesting / Breeding

Hummingbirds are solitary in all aspects of life other than breeding; and the male’s only involvement in the reproductive process is the actual mating with the female. They neither live nor migrate in flocks; and there is no pair bond for this species. Males court females by flying in a u-shaped pattern in front of them. He will separate from the female immediately after copulation. One male may mate with several females. In all likelihood, the female will also mate with several males. The males do not participate in choosing the nest location, building the nest or raising the chicks.

The female is responsible for building the cup-shaped nest out of plant fibers woven together and green moss on the outside for camouflage in a protected location in a shrub, bush or tree about 3m above ground often near the tip of a descending bamboo stem.

She lines the nest with soft plant fibers, animal hair and feather down, and strengthens the structure with spider webbing and other sticky material, giving it an elastic quality to allow it to stretch to double its size as the chicks grow and need more room. The nest is typically found on a low, thin horizontal branch.

The average clutch consists of two to three white eggs, which she incubates alone for about 15 – 19 days, while the male defends his territory and the flowers he feeds on.

The young are born blind, immobile and without any down.

The female alone protects and feeds the chicks with regurgitated food (mostly partially-digested insects since nectar is an insufficient source of protein for the growing chicks). The female pushes the food down the chicks’ throats with her long bill directly into their stomachs.

As is the case with other hummingbird species, the chicks are brooded only the first week or two, and left alone even on cooler nights after about 12 days – probably due to the small nest size. The chicks leave the nest when they are about 20 – 26 days old.

Diet / Feeding

They primarily feed on nectar taken from a variety of brightly colored, scented small flowers of trees, herbs, shrubs and epiphytes.
