This medium-sized hummingbird is common in gardens and forest edges across southeastern South America and readily visits feeders and flowering shrubs. It fiercely defends nectar sources, chasing off rivals with rapid aerial pursuits. Its cup-shaped nest is made of plant down and spider silk, often placed on a horizontal branch under sheltering leaves. By visiting a wide range of flowers, it acts as an important pollinator in the Atlantic Forest biome.
Temperament
territorial and energetic
Flight Pattern
short rapid wingbeats with sustained hovering and swift darting chases
Social Behavior
Typically solitary at flowers, with males aggressively defending feeding territories. During breeding, the female builds a small cup nest of plant fibers and spider silk and alone incubates and feeds the young. Courtship involves chases and display flights around nectar sources.
Migratory Pattern
Partial migrant
Song Description
Vocalizations are a series of thin, high-pitched chips and squeaky notes given while foraging or during chases. Wing hum is audible at close range and intensifies during aggressive interactions.
