Rufous Hummingbird

Identification

The rufous hummingbird is a tiny bird, measuring 7–9 cm long with a wingspan of 11 cm and weighing just 2–5 grams. Despite its diminutive size, it is unmistakable in appearance. The adult male displays a striking white breast contrasted with rufous face, flanks, and tail, crowned by an iridescent orange-red throat patch or gorget. Some males show green on their back and crown. Females are slightly larger than males and feature green plumage with white and iridescent orange feathers in the center of the throat, a dark tail with white tips, and a rufous base. The typical notched shape of the second rectrix feather is an important field mark for distinguishing adult male rufous hummingbirds from the similar Allen's hummingbird. Females and green-backed males can be difficult to differentiate from Allen's hummingbird without close inspection.

Range & Habitat

Western rufous hummingbirds breed in open areas, mountainsides, and forest edges across western North America, ranging from southern Alaska through British Columbia and the Pacific Northwest to California—nesting farther north than any other hummingbird species. From May to September, they migrate through the Rocky Mountains and nearby lowlands to exploit the wildflower season, often staying in one region for the entire summer. The species undertakes one of nature's most remarkable migratory journeys: most individuals winter in wooded areas in the Mexican state of Guerrero, traveling over 3,200 kilometers by overland routes—an extraordinary distance for a bird weighing only 3–4 grams. Adult males tend to migrate slightly earlier than females or juveniles.

Behaviour & Diet

Rufous hummingbirds feed on flower nectar using their long, extendable tongue, and also catch insects on the wing. They require frequent feeding throughout the day and become torpid at night to conserve energy. During hovering, they support their body weight primarily through wing downstrokes, which provide 75 percent of lift, with upstrokes contributing 25 percent. Both males and females are highly territorial, but defend different types of territories. Aggressive males fight to monopolize areas dense with flowers, pushing females into sparser feeding zones. Males possess shorter wings, resulting in higher hovering metabolic costs, but this allows them to beat their wings at high frequencies for chasing rivals. Females, excluded from rich food sources, have longer wings that enable more efficient long-distance flight between scattered flowers. Females build nests in protected locations within shrubs or conifers, while males are promiscuous, mating with multiple females.

Best Time & Places to See It

To observe rufous hummingbirds during breeding season, visit open areas, mountainsides, and forest edges throughout western North America from May to September, with the best viewing opportunities in the Pacific Northwest and California. They may remain in a single region for the entire summer. Migrants are visible passing through the Rocky Mountains and nearby lowlands during these months. Winter sightings are possible in wooded areas of Guerrero, Mexico, though the species is far less accessible there. Spring and early summer offer the most reliable viewing, as adult males migrate earlier than females and juveniles.

Photography Tips

Photograph rufous hummingbirds near flowering plants, particularly areas with dense wildflowers that attract territorial males. The male's iridescent orange-red gorget is spectacular when lit correctly—position yourself to catch side-angle or backlit shots that make this throat patch gleam. Fast shutter speeds are essential to freeze their rapid wing beats and hovering flight. Early morning or late afternoon light will enhance the metallic coloration. Look for males defending flowering territories aggressively; their combative behavior provides dynamic action shots. Female plumage is more subtle, so ensure adequate lighting to capture the iridescent orange feathers in their throat center and the distinctive white-tipped dark tail.
