Glaucis hirsutus
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 1,500 m.
The habitat suitability model generated in Maxent showed a very few areas that are suitable in climatic terms for this species in the Alta Guajira. 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 92,619 km2, which corresponds to a loss of 70 % of its potential original distribution due to deforestation in the region west of the Andes and about 472,918 km2, which corresponds to a loss of 10 % in the Amazonia. However, it is important to note that this species favours borders, secondary growth and semi-open areas and in this sense it might have been favoured by deforestation to certain extent.
