Does signal deterioration compromise eavesdropping on other species' alarm calls?
Individuals gain valuable information by eavesdropping on others species' signals, but there are potentially greater constraints on eavesdropping than reception of signals from conspecifics. Eavesdroppers rely on signals addressed to others, which may come from unpredictable directions and distances. Furthermore, eavesdroppers might lack familiarity with other species' calls or perceptual adaptations to detect and recognize them, and these difficulties may be exacerbated by signal changes...[Show more]
