Calliphlox amethystina


To elaborate our model we removed uncertain localities such as those localities with no coordinates, 'Bogota skins' and all records with coordinates laying down in sites with estimated elevations above 420 m.

The habitat suitability model generated in Maxent showed some areas suitable in climatic terms for this species west of the Andes including areas along the Pacific slope of the Western Andes, the northern Choco and few sections of the Central Andes and the western slope of the Eastern Andes. Those areas are not known to be occupied by this species and were deleted from our final potential distribution map. It is important to highlight that an extensive area in the northwestern and southern Amazonia were not predicted as suitable by our model and this was noted in our maps.

Assuming that the distribution of the species may have filled the complete climatic model generated plus the areas not predicted but likely suitable, its distribution today in remnants of forest is about 425,753 km2, which corresponds to a loss of 8 % of its potential original distribution due to deforestation.

Apparently in Colombia is very local and very poorly known (HBW Alive 2017).
