Resumen

In the Amazon, increasing degradation and biodiversity loss underscore the need to identify areas of high environmental suitability to preserve habitats and ensure the survival of flora and fauna. A significant challenge is the lack of baseline data for many species, particularly in Loreto, Peru. This study modeled the potential distribution of two key bird species: Harpia harpyja “Harpy eagle” and Sarcoramphus papa “King vulture”, using georeferenced records, bioclimatic variables, and the Maxent algorithm. For H. harpyja, optimal habitats were mainly found in the northern and eastern regions of Loreto, specifically in Putumayo, Mariscal Ramón Castilla, and Maynas, with mean diurnal temperature range and annual precipitation as crucial factors. In contrast, S. papa showed greater suitability in the north, southeast, and southern parts of the region, especially in Requena and Mariscal Ramón Castilla, where mean annual temperature and temperature range significantly influenced its distribution.
