Campylopterus largipennis

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 below 71 m above 1,156 m. Also three records in BioMap from Cauca and two more in DatAves from Valle del Cauca and Antioquia, which represent corrupted information in the database were deleted previous to modelling.

The habitat suitability model generated in Maxent showed 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. Also is important to note that some areas in the southern Orinoco region (south of rio Meta) were not predicted as suitable by our model, these areas were noted as such in our maps.

Assuming that the distribution of the species may have filled the complete climatic model generated in the Amazon region, its distribution today in remnants of forest is about 473,156 km2, which corresponds to a loss of 9 % of its potential original distribution due to deforestation in that region.
