Typical Environment
Occurs in humid montane and elfin forests, forest edges, and shrubby clearings with abundant flowering plants. It frequents ravines, streamside thickets, and forest borders where ericaceous shrubs, bromeliads, and melastomes are common. The species is most often seen at mid to upper elevations, where it forages from midstory to canopy level. It also visits flowering gardens and roadside vegetation near forest.

This medium-sized hummingbird is restricted to the isolated Sierra Nevada de Santa Marta massif of northern Colombia. Males are notably striking with bold white in the tail that flashes in flight, a key field mark even in dim cloud-forest light. It patrols flowering shrubs aggressively, often defending rich nectar sources from other hummingbirds. Like many high-Andean hummingbirds, it also supplements its diet with small arthropods for protein.
Temperament
territorial and active
Flight Pattern
short rapid wingbeats with agile hovering
Social Behavior
Typically solitary when foraging and strongly territorial at rich flower patches, where males chase intruders. Courtship involves aerial chases and display flights near favored blossoms. Nests are small, cup-shaped structures placed on sheltered branches or in shrubs, often near streams.
Migratory Pattern
Resident
Song Description
Vocalizations are high, thin chips and short twitters delivered from perches or while foraging. The rapid wing hum is audible at close range, especially during aggressive chases.
