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 1,864 m.
The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this species in the high Cauca Valley, east of the Magdalena river particularly in the mid Magdalena Valley, the slopes above the inter-Andean valley and in the eastern slope of the Eastern Andes. These areas are not known to be occupied by the species and were excluded from the potential distribution map of this hummingbird.
Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 79,046 km2, which corresponds to a loss of 42 % of its potential original distribution due to deforestation.
Regularized training gain is 2.085, training AUC is 0.965, unregularized training gain is 2.375.
Algorithm converged after 740 iterations (20 seconds).
The follow settings were used during the run:
42 presence records used for training.
10041 points used to determine the Maxent distribution (background points and presence points).
