To elaborate our models 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 below 290 m and above 2,200 m.
The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this hummingbird extensively west of the Andes. Thus we retained areas in the East Andes and the east slope of the Central Andes including serrania de San Lucas, as well as a few areas in the border with Panama. Otherwise, most areas were deleted from our final potential distribution map for this species. Areas in the southern portion of the eastern slope of the Eastern Andes were left in our map since they are climatically suitable although there are no known records from them.
Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 71,358 km2, which corresponds to a loss of 58 % of its potential original distribution due to deforestation.
Regularized training gain is 0.774, training AUC is 0.893, unregularized training gain is 1.117.
