Coeligena conradii


To elaborate our model we removed uncertain localities such as 'Bogota skins', those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations below 1,500 m and above 3,650 m.

The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this species in the high Cauca Valley, the Central Andes, the low Magdalena Valley and the 'Alta Guajira'. Those areas are not known to be occupied by this species and were deleted from our final potential distribution map. Areas south of approximately Santander were left in our potential map as part of a possible extended range in case it is proven specimens from near Bogota are correctly identified as conradii.

Distribution of specimens according to BioMap suggest the species possibly goes south as far as Bogota. Nevertheless, this requires further studies to confirm it and clarify better the distribution of the species in Colombia.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 3,077 km2, which corresponds to a loss of 68 % of its potential original distribution due to deforestation.

Further taxonomic studies needed to clarify relationships between C. torquata, C. conradii, C. eisenmanni and C. inca.

C. conradii usually considered a subspecies of C. torquata.

The distribution of the species is small in Colombia and it needs some conservation attention if it is intended to conserve it in the country.
