Heliothryx auritus

NOTES

To elaborate our model we removed uncertain localities such as 'Bogota skins' and all records with no coordinates.

The habitat suitability model generated in Maxent showed extensively areas suitable in climatic terms for this species west of the Andes. 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 in the Amazon Region is about 474,138 km2, which corresponds to a loss of 9 % of its potential original distribution due to deforestation in that region.
