Anti-predator behaviors of free-ranging groups of equatorial saki monkeys (Pithecia aequatorialis) were recorded in the Área de Conservación Regional Comunal Tamshiyacu Tahuayo in the Peruvian Amazon to determine whether individuals responded in predator-specific ways to calls of aerial and terrestrial predators. Previous studies have shown that several species of Old World monkeys possess these discriminative abilities, but few have explored this question in New World monkeys. The ability to recognize predators and to respond appropriately is important for survival. Thus, we predicted that equatorial saki monkeys should respond in predator-specific ways, both vocally and behaviorally, to aerial and terrestrial predators. …
