Distribution
This species can be found in Colombia and a small part of Venezuela.Habitat
Its habitat is subtropical or tropical moist montane forests. It follows a habitual path or "trap-line" with stops at flowering plants such as ''Bomarea'', ''Cavendishia'', ''Fuchsia'', ''Macleonia'', ''Mutisia'', and ''Palicouria'', whose nectar it feeds on. It also catches insects in flight and gleans them off plants. In general its behavior is probably similar to that of the golden starfrontlet, which may be a subspecies of this species.References:
