Impact of predator model presentation paradigms on titi monkey alarm sequences.

ABSTRACT:

Abstract

Predator presentation experiments are widely used to investigate animal alarm vocalizations. They usually involve presentations of predator models or playbacks of predator calls, but it remains unclear whether the two paradigms provide similar results, a major limitation when investigating animal syntactic and semantic capacities. Here, we investigate whether visual and acoustic predator cues elicit different vocal reactions in black-fronted titi monkeys (Callicebus nigrifrons). We exposed six groups of wild titi monkeys to visual models or playbacks of vocalizations of raptor or felid. We characterized each group's vocal reactions using sequence parameters known to reliably encode predatory events in this species. We found that titi monkeys' vocal reactions varied
