Crypturellus variegatus

NOTES

The habitat suitability model generated in Maxent showed extensive areas that are suitable in climatic terms for this species west of the Andes. It is well known these areas are not occupied by this species and they were excluded from its potential distribution map. Interestingly, the model also predicted more areas than expected in the Orinoco region, some of them may be in fact occupied by this tinamou, particularly in the centre, south and east of the region.

Assuming the distribution of the species may have filled the complete climatic model generated in the Amazon region of Colombia, its distribution today in remnants of forest is potentially about 469,891 km², which corresponds to a loss of 9 % of its potential original distribution in the region due to deforestation.
