New publication on non-vocal communication in howler monkeys On a recent publication of an article in Mammalogy Notes, titled "Observation of an apparently human-directed agonistic throat display in two adult males of Alouatta caraya (Atelidae: Primates) in Pilar, Paraguay", our PhD student Mikel Redin presents the first documented record of an unusual throat display behaviour in black-and-gold howler monkeys. 24 de març 2025 Recerca i transferència Publicacions
In this study, the authors describe how two adult males living in urban environments performed a non-vocal, low-energy throat display apparently directed at human observers. This ritualized behaviour may function as a low-cost threat display, replacing loud vocalizations, and offers new perspectives on how primates adapt their communication strategies in urban environments. The research highlights the importance of studying animal behaviour in anthropogenic habitats and raises new questions about the implications of multimodal forms of communication in a vocal primate species.
