White crests are symbols of different stripes among antelopes

The nyala and springboks are southern African bovids both possessing white, erectile dorsal crests. However, the functions of these crests could hardly differ more. In the nyala, the crest is restricted to the male and crowns the display of male rivalry. By contrast, in springboks the crest is never erected to show masculinity but is the main feature displayed in a different type of competition: display of fitness to predators. Accordingly, the crest is raised mainly by mature males of the nyala compared to juveniles of springboks.
