Antelope are herbivores, which means they eat only plants. Although there is 1 odd exception: some duiker species have been known to kill and eat insects, small mammals, and birds. The majority of antelope tend to be content to munch on bushes and smaller trees or graze on grass.
All antelope have horns; in some species they are only found on the males, whereas in others, such as gazelles, both males and females have them. The horns are made of a bony core encased in a hard material made largely of keratin (the same substance our fingernails are made of!).
Antelopes are in the family Bovidae. A group of antelope is called a herd. Both the male and female antelope have horns, but those of males tend to be larger.
