To elaborate our models we removed uncertain localities such as those with no coordinates and all records with coordinates laying down in sites with estimated elevations above 540 m.
The habitat suitability model generated in Maxent showed areas suitable in climatic terms for this hummingbird in most of the lowlands of the country suggesting a very low specificity. Sensu lato the species must occupy most of the Amazonia and therefore its final potential range was circumscribed to that region.
Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 478,393 km2, which corresponds to a loss of 9 % of its potential original distribution due to deforestation.
Regularized training gain is 0.079, training AUC is 0.611, unregularized training gain is 0.161.
Algorithm converged after 60 iterations (0 seconds).
