There are six 'Bogota' skins in BioMap probably collected near Villavicencio and one sighting in Antioquia in ProAves Database, which is clearly erroneous. These accessions were removed when modelling the distribution of this species. On the other hand, to produce the model we added one more record from San Teodoro (Vichada) found in EBIRD.
The habitat suitability model generated in Maxent showed a few areas that are suitable in climatic terms for this species west of the Andes in Sierra Nevada de Santa Marta, the northern end of the three cordilleras, the high Patia valey and some areas in the mid-high Magdalena valley. These areas are known not to be occupied by the species and were excluded from the potential distribution map of this guan.
Assuming that the distribution of the species may have filled the complete climatic model generated in the Amazon region, its distribution today in remnants of forest is about 475,080 km2, which corresponds to a loss of 9 % of its potential original distribution due to deforestation in that region of Colombia.
Regularized training gain is 1.170, training AUC is 0.911, unregularized training gain is 2.279.
Algorithm converged after 980 iterations (26 seconds).
