Many species approach, inspect, and signal toward their predators. These behaviours are often interpreted as predator-deterrent signals—honest signals that indicate to predators that continued hunting
There are many factors that affect signal design, including the need for rapid signal detection and the ability to identify the signal as conspecific. Understanding these different sources of selectio
Behavioural responses to communicative signals combine input from multiple sensory modalities and signal compensation theory predicts that evolutionary shifts in one sensory modality could impact resp
