The Ontogeny of "Twitter" Calls in White-Faced Capuchins (Cebus imitator): Usage, Context, and Acoustic Structure.

ABSTRACT: In stark contrast to our own highly plastic communicative abilities, nonhuman primate vocalizations were historically considered fixed and innate, with very little ability to learn or modify vocal signals. However, recent studies indicate that primate vocalizations do show evidence of developmental plasticity, most notably in their context and usage. We build on these studies by investigating developmental changes in one of the most common calls of white-faced capuchins (Cebus imitator), the twitter. Specifically, we examined the behavioral context around twitter vocalizations in a wild population of white-faced capuchins in the Taboga Forest Reserve, Costa Rica. We analyzed the use of twitters in relation to behavioral state (social, foraging, travel, or resting), immediate context (appro
