We tend to think of antelope as living in big groups, but not all species form large herds. Some antelope are famous for their massive herds, like the thousands of wildebeest making their annual migration across the African plains. Others, like duikers, bongos, dik-diks, and sitatungas, live alone, in pairs, or in small groups of between 3 and 10 animals. The social life of antelope depends a lot on the type of habitat they live in and how much food and water is available.

Some antelope species, like impalas, springbok, and saigas form very large herds during migratory seasons when they are on the move to find the best food. The males are not usually territorial at these times, but they may separate out during the breeding season and stake out a territory where they compete for females. They may also use size or strength displays or threaten with their horns to determine which male is dominant and to keep females.

Many antelope that live in large groups at least part of the year also have special scent glands on their hooves, so they leave the herd’s scent on the ground for any stray members to find.

In territorial species like sable antelope, oryx, waterbuck, bontebok, and gazelles, the males choose a particular piece of habitat and defend it from other adult males. Herds of females and their young can come and go freely, although in the breeding season the male tries to keep them in his territory. If he has a stream or shady tree in his area, he’s more likely to keep the females around.

The territorial males of these species also mark their territory with secretions from special scent glands and with urine and dung piles. Males that are not quite full grown or that have not established a territory form bachelor herds.

Antelope are herbivores, with an odd exception: some duiker species have been known to kill and eat insects, small mammals, and birds. Otherwise, antelope tend to be either browsers or grazers. Some species switch back and forth, eating whatever is most nutritious or what’s available during dry or cold times of the year.

Some antelope have special feeding adaptations for their environments. Addaxes know to follow the rains, traveling great distances to eat the new plant growth. Thomson’s gazelles follow herds of migrating wildebeest and zebras, which eat the tougher layer of grasses and leave the shorter, more tender shoots behind. Perhaps two of the oddest-looking antelope are the gerenuk and the dibatag, both of which have slender bodies, long thin legs, and very long necks. They can stand upright on their hind legs and stretch up with those long necks to eat leaves that other species can’t reach!

Antelope calves have two survival strategies: either they hide out to avoid predators or they start traveling right after birth so they can join the protection of the herd.

The majority of antelope use the hiding approach, like elands, greater kudu, roan antelope, waterbucks, klipspringers, and duikers. In some species that live in groups, the mother, called a dam, goes away from the herd to give birth, and when the calf is strong enough, she moves it to another location where there are bushes, long grasses, rocks, or a thicket to hide the youngster from predators. The dam then rejoins the herd, and the calf remains hidden and quiet. She comes back periodically to feed the calf, calling softly to it and listening for the bleat.

Between a week and a month or more, depending on the species, the calf then joins the herd and may be put with the other calves in what’s known as a nursery group. In more solitary species, the dam hides her calf and then stays nearby to guard it as she feeds, returning to nurse it when needed. When the calf is strong enough, it joins her, and they stay together until the calf is mature and heads out on its own.

In species that migrate or live in large ranges, like the hartebeest, topi, bontebok, and wildebeest, the calves are up and on their feet within a few minutes to a day or so after they are born, and they immediately start traveling with the herd. They often stick together as a group and are protected by adults surrounding them. This way they don’t get left behind and can nurse from their mothers. If danger approaches, the adults can face the challenge with their strength and their horns.
