Phaethornis ruber

NOTES

To elaborate our model we removed uncertain localities such as 'Bogota skins' and all records with coordinates laying down in sites with estimated elevations above 636 m. Also eight records in BioMap and one in DatAves from Valle del Cauca, which clearly represent corrupted data, were removed previously to modelling.

The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this species extensively west of the Andes in the biogeographic Choco and the mid to mid-high Magdalena Valley. These areas are not known to be occupied by the species and were excluded from the potential distribution map.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 463,601 km², which corresponds to a loss of 9 % of its potential original distribution due to deforestation just in the Amazonian Region of Colombia.
