Typical Environment
Occurs on tepui slopes and summits, in montane evergreen forest, elfin forest, and scrubby edges. It frequents forest margins, clearings with flowering shrubs, rocky outcrops, and streamside thickets. The species often forages along ecotones where sunlit patches promote prolific flowering. Locally common around abundant nectar sources but patchy elsewhere.

800–1800 m

A large hummingbird of the Guiana Highlands, the rufous-breasted sabrewing specializes on nectar from tubular flowers and also takes tiny insects for protein. Males defend rich flower patches aggressively, often chasing other hummingbirds. The name “sabrewing” refers to the male’s broadened outer primaries that resemble a sabre. It is an important pollinator of highland flora on the tepuis.
Temperament
territorial and active
Flight Pattern
short rapid wingbeats with agile hovering
Social Behavior
Generally solitary while feeding and strongly territorial at rich flower patches; males chase intruders vigorously. Nest is a small cup of plant fibers and spider silk placed on a horizontal branch or overhanging stream. The female alone incubates and tends the young. Breeding likely coincides with peak flowering in the wet season.
Migratory Pattern
Resident
Song Description
Mostly a series of thin, high-pitched chips and twitters, interspersed with buzzy trills. Wing hum is loud at close range, and vocalizations intensify during territorial interactions.
