NOTES
To elaborate our model we removed uncertain localities such as those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations above 749 m.
The habitat suitability model generated in Maxent showed a few pixels suitable in climatic terms for this species in far east Amazon region in the Rio Negro valley. These areas are not known to be occupied by the species and were excluded from the potential distribution map of this hummingbird. The model predicted a few pixels south of 'Cienaga Grande de Santa Marta' that were left to inform, although it is unlikely the species reaches that area.
