Mitu tuberosum

NOTES

The habitat suitability model generated in Maxent showed a few areas that are suitable in climatic terms for this species east of the Andes in the Catatumbo and west of the Andes in the low Magdalena valley, the inter-Andean valleys and the Patia valley. Those areas are not known to be occupied by this curassow and were excluded from its potential distribution map. It is important to bear in mind that our model was elaborated with just three locality records and therefore in that sense it is relatively limited. Nevertheless, it gives a first good approximation of the potential distribution of this species in Colombia.

Assuming that the distribution of the species may have filled the areas predicted as suitable (i.e. marginally suitable, suitable and highly suitable) and not predicted as suitable in its most likely area of distribution south of the Caqueta river, its potential distribution today in remnants of forest is about 68,956 km², which corresponds to a loss of 2 % of its potential original distribution due to deforestation.
