Bluish-slate Antshrike
Thamnomanes schistogynus |
Predator information networks exist across prey species where they share predators, but to what extent does predator-specific vulnerability determine which alarm signals are valued across species? Antshrikes and Primates live in shared habitats in neotropical forests. Both of these species are hunted by similar predators and both species produce alarms to warn conspecifics of threats. |
Sadde-backed Tamarin
Saguinus fuscicollis |
Tamarins responded significantly to antshrike alarms and vice versa. We conclude that signals are highly valued even across broad taxa when predators are shared. These data support the hypothesis that overlap in shared predators can drive the mutual recognition and use of alarm calls across widely distinct taxonomic groups.
