Resumen

This study presents the diet of the Andean fox (Pseudalopex culpaeus) in the Rio Abiseo National Park situated in the high Andes of Peru. Results of the 74 scats analyzed showed a total of 180 prey consumed. This consisted primarily of rodents (48 %), followed by berries of Vaccinium (Ericaceae, 29 %), birds (12 %), frogs (6 %) and insects (5 %). Eighty two percent of the total vertebrate prey weighted less than 55 g. A comparison with other studies on Andean fox diet in Argentina, Chile and Peru, confirm its omnivorous opportunistic diet from almost totally carnivorous to highly omnivorous. Comparisons of the Andean fox diet with that of other large predators present at Rio Abiseo N.P. suggest their differences in prey preference
