stotting

n. a stiff-legged jumping display, shown by many species of ungulates, in which all four legs are off the ground at the same time. Stotting appears to communicate to predators that the individual has detected them and has enough vigor to make capture difficult. Studies show that predators are more likely to give up a hunt when an animal stots.
