Giant Hummingbird

Overview

The Giant Hummingbird is the largest species of hummingbird in the world, found along the Andes and adjacent lowlands of western South America. Unlike many of its dazzling relatives, its plumage is relatively subdued, and it is often first noticed by its size and unusually slow wingbeat rather than by bright iridescent color.

Its larger body size changes its flight style noticeably compared to smaller hummingbirds, with slower, more powerful wingbeats that can even be visible to the naked eye rather than appearing as a blur.

Feather ID Notes

Feathers lack the intense, saturated iridescence typical of many hummingbirds, instead showing brownish-gray to bronze-green upperparts and buffy-cinnamon underparts with a somewhat matte appearance. The tail is dark and can show a scaled pattern on the breast in some individuals.

• Upperpart feathers: brownish-gray to bronze-green, subdued
• Underpart feathers: buffy-cinnamon, sometimes lightly scaled or streaked
• Tail feathers: dark, moderately long
• Overall size: much larger than any other hummingbird, an immediate clue The combination of large size and relatively dull, non-iridescent plumage separates this species from all other hummingbirds sharing its range.

Plumage Details

Sexes are similar in the Giant Hummingbird, both showing the same subdued brownish-gray and buffy coloring, with little sexual dimorphism compared to most hummingbird species. Juveniles show finer feather scaling on the underparts. There is no strong seasonal plumage change, with an annual molt maintaining feather condition.

Habitat & Range

This species occupies arid to semi-arid Andean valleys, scrubland, agricultural areas, and gardens from Ecuador south through Peru, Bolivia, Chile, and Argentina, generally at moderate to high elevations. Some populations undertake seasonal elevational movements, descending to lower valleys outside the breeding season, while others are more sedentary.

Behavior & Field Notes

Giant Hummingbirds feed on nectar from a variety of Andean flowering plants, including cacti and agave-like species, and also take small insects. Their larger body size allows for a distinctive hovering flight with slower, deeper wingbeats than smaller hummingbirds, sometimes even appearing to glide briefly between beats. Nests are cup-shaped structures built in shrubs or on rock ledges. Calls include a range of chattering and squeaky notes.
