Overview

Wildebeest, also called gnus, are large African antelopes of the genus Connochaetes. With a heavy head, sloping back, and shaggy mane, they look almost cattle-like, but they belong firmly to the antelope group. The animal shown here is the blue wildebeest (Connochaetes taurinus).

Wildebeest are best known for forming enormous herds, and in some regions for long seasonal migrations that move with the rains. As abundant grazers and prey, they are a keystone presence in the savanna food web.

Conservation note: wildebeest are widespread, but individual populations depend on intact, connected grasslands and migration routes. Verify current species and population status at iucnredlist.org.

Wildebeest are bovids, the same family as cattle, buffalo, sheep, goats, and other antelopes. The two species are the blue wildebeest and the black wildebeest (Connochaetes gnou).

Habitat & Range

Blue wildebeest inhabit open grassland and savanna across eastern and southern Africa, favouring short-grass plains and lightly wooded country near water. Black wildebeest are associated with open grassland and shrubland in southern Africa.

Migration & Movement

In some ecosystems, blue wildebeest undertake large-scale seasonal movements, tracking rainfall and the flush of new grass and crossing rivers where predators and other hazards await. These migrations involve very large numbers of animals and are among the most striking wildlife spectacles on land. Not all wildebeest populations migrate; some are more sedentary.

Diet & Feeding

Wildebeest are specialised grazers of short grasses. Because their grazing depends on grass condition and water, herd movements and migrations are closely tied to seasonal patterns of rainfall and plant growth.

Behavior & Social Life

Wildebeest are highly social and gregarious, gathering in herds that can be immense during migrations. Calving is often synchronised, with many young born in a short window — a strategy thought to improve calf survival by overwhelming predators. Males may hold temporary territories during the breeding season.

Appearance & Recognition

The blue wildebeest is grey-brown with faint darker vertical stripes on the forequarters, a dark mane and beard, and curved horns in both sexes. The large head set low on a robust body and the sloping back give it a characteristic silhouette, especially when seen in the long lines of a moving herd.

Human Interaction & Conservation

Wildebeest are central to tourism and to the ecology of famous protected areas, but migratory populations are sensitive to fences, land conversion, and barriers that cut migration routes. Conservation focuses on keeping large landscapes connected. Consult authoritative sources for current status.

Frequently Asked Questions — Wildebeest

Is a wildebeest an antelope?
Yes. Wildebeest (also called gnus) are large antelopes in the family Bovidae. Two species are recognised: the blue wildebeest (Connochaetes taurinus) and the black wildebeest (Connochaetes gnou). Despite a cattle-like, heavy-headed appearance, they belong to the antelope group.
Why are wildebeest famous for migration?
Blue wildebeest in parts of East Africa take part in large seasonal movements following rainfall and fresh grazing, forming some of the largest herds of any land mammal. These migrations, often alongside zebras and gazelles, are a defining feature of certain savanna ecosystems.
What do wildebeest eat?
Wildebeest are grazers that feed mainly on short grasses. Their movements are closely tied to grass growth and water, which is one reason migratory populations travel so far in search of suitable grazing through the year.
What is the difference between blue and black wildebeest?
The blue wildebeest is larger, grey-brown with darker vertical stripes, and includes the famous migratory populations of East Africa. The black wildebeest is smaller, dark-bodied with a distinctive forward-curving horn shape and an upright pale tail, and is native to southern Africa. This profile uses the blue wildebeest as the reference.
