Two prominent forms of display among these animals is whistling and bounding. Instead of scent-marking its territory, the reedbuck will give a shrill whistle to make the boundaries of its territory be known. As it whistles, it expels air through its nose with such a force that the whole of its body vibrates. These whistles, usually one to three in number, are followed by a few stotting bounds. This behavior is also used to raise alarm in herds. In this, the reedbuck raises its neck, exposing the white patch on its throat, but keeping the tail down, and leaps in a way similar to the impala's jumps, landing on its forelegs. This is accompanied by the popping of the inguinal glands in the legs. Fights begin with both opponents holding their horns low, in a combat stance; followed by the locking of horns and pushing one another. These fights can even lead to deaths.
