Crypturellus duidae


The habitat suitability model generated in Maxent showed extensive areas that might be possibly occupied by this species west of the Andes. Nevertheless, it is well known the species is just present east of the Andes and therefore these were removed from the potential distribution map of this species.

It is necessary to bear in mind that this model was elaborated using just three point localities, from where this species is known in Colombia. The model is useful in the sense that can give an indication of the potential areas where the species may be looked for in the country. The distribution of this rare and local species is extremely unknown in Colombia. Additionally, we added four other points from where the species is known in Venezuela and Ecuador (EBIRD) and produce a minimum convex polygon as a general guidance of the most likely areas where the species may be in Colombia within our model.
