Quick answer
Key facts about wildebeest — size, diet, habitat, and conservation in one place.
The great migration
Over a million blue wildebeest circle the Serengeti–Mara ecosystem annually, tracking rain and grass growth. River crossings at the Grumeti and Mara expose them to crocodiles — one of nature's most dramatic wildlife spectacles.
Calving synchrony
Most calves are born within a few weeks at the start of the rains, overwhelming predators with sheer numbers. Calves stand within minutes and join the herd within days, essential for survival on open plains.
Gnu behaviour
Wildebeest form mixed herds with zebra and topi, combining grazing styles to use different grass layers. Their snorting, gnu-like calls and shaggy manes give them a distinctive silhouette on African savannas.
Threats and fencing
While Least Concern globally, migratory populations depend on open corridors. Fences, farmland expansion, and drought disrupt ancient routes. The Serengeti–Mara system remains the migration stronghold.
