Phaethornis bourcieri


To elaborate our model we removed uncertain localities such as all records with coordinates laying down in sites with estimated elevations above 800 m. Also five records in ProAves, three from Antioquia and two from Magdalena, and a further two records in BioMap and DatAves from Choco, which represent corrupted data were removed previously to modelling.

The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this species west of the Andes, particularly in the Pacific Region. These areas are not known to be occupied by the species and were excluded from the potential distribution map. Otherwise, a few areas east of the Andes that potentially are occupied by the species were not predicted by our model, these were highlighted as such in our maps.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 419,447 km2, which corresponds to a loss of 11 % of its potential original distribution due to deforestation.
