The evolution of movement-based signals is constrained by the successful segmentation of relevant movements from motion noise by the visual system of receivers. We tested five Jacky dragons, Amphibolurus muricatus, a species characterized by stereotyped movement-based social signals, for their ability to discriminate the direction of drifting dots against simulated background motion noise of varying angular speeds. Results from trials with artificial (dot) backgrounds suggested that Jacky...[Show more]
