Currently, there are computer tools that, combined with biological knowledge, allow us to identify optimal occupation areas based on ecological requirements that are key to species conservation. However, for many species this baseline is non-existent, especially in the department of Loreto, Peru. The present work generated ecological niche models for H. harpyja and S. papa, to infer environmental suitability, estimate potential distribution and identify bioclimatic requirements, in which occurrence data and bioclimatic variables were used, the models were generated through the “Kuenm” package using the Maxent algorithm. Our models indicated that for H. harpyja the ideal conditions of occurrence were in the north and east of the region, in the provinces of Putumayo, Mariscal Ramon Castilla, Maynas and small patches in Ucayali, with an approximate potential distribution of 355565.75 km...

The use of computational tools combined with biological knowledge allows the identification of optimal areas of occupancy based on ecological requirements, which are key for species conservation. However, for many species, this baseline is lacking, especially in the department of Loreto, Peru. This study generated geographical distribution models for two Amazonian bird species: Harpia harpyja “harpy Eagle” and Sarcoramphus papa “King Vulture”. Using a combination of geographic occurrence data and bioclimatic variables, the modeling was conducted with the Maxent algorithm. Our models indicated that for H. harpyja, the optimal conditions of occurrence were located in the north and east of the department, in the provinces of Putumayo, Mariscal Ramón Castilla, and Maynas, with the most important bioclimatic variables being the mean diurnal temperature range and annual precipitation....
