To elaborate our model we removed uncertain localities such as 'Bogota skins', those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations above 300 m.
The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this species in the whole biogeographic Choco, the interandean valleys and the low Cauca and Magdalena and some areas in western Amazon and Orinoco regions. These areas are not known to be occupied by the species and were excluded from the potential distribution map of this hummingbird.
Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 428,175 km2, which corresponds to a loss of 3 % of its potential original distribution due to deforestation.
Recent studies suggest that this species may be better placed within genus Amazilia (HBW Alive, 2017).
Regularized training gain is 0.335, training AUC is 0.809, unregularized training gain is 0.534.
