To elaborate our model we produced four pseudoreplicas of the only known sighting we found for this species in the country in Hilty & Brown (1986). The new points were located at approximate 1.5-3 km west, northwest, north and east from the original locality.
The habitat suitability model generated in Maxent showed a few small areas suitable in climatic terms for this species in eastern Norte de Santander, southern Cesar, central Antioquia, southern Huila and central Nariño. Areas off the 'Trapecio Amazonico' were excluded from the potential distribution map of this hummingbird. Might be possible that the whole Trapecio has areas suitable for this species, however, further areas where not highlighted.
This species is distributed in central South America and its geographical range has been estimated in 4,040,000 km2. Colombia represents the outskirts of its distribution to the north. There are no collected skins and its presence in the country is hypothetical. It is not known if it is present in the country seasonally or as a vagrant and its general ecology in the country is poorly known. It needs further research to know better is distribution in Colombia and ecology.
Regularized training gain is 5.516, training AUC is 1.000, unregularized training gain is 6.768.
