The blue wildebeest (Connochaetes taurinus), sometimes known as the gnu, is an antelope species. Their heads are huge and boxy, with curved horns. Their forequarters are bulky, but their hindquarters are small with spindly legs. They have a gray coat and a black mane, as well as a black or white beard. Wildebeest come in a variety of races. The western white-bearded wildebeest inhabits the Serengeti-Mara habitat of Kenya and Tanzania, whereas the eastern white-bearded subspecies occupy Kenya and Tanzania east of the Gregory Rift. The blue or brindled race exists south of the Zambezi River. The intimidating look of the ungainly gnu (pronounced “g-new” or simply “new”) gained it the Afrikaans moniker wildebeest, or “wild beast,” because to its huge head, shaggy mane, pointed beard, and sharp, curving horns. In truth, the wildebeest is best regarded as a dependable supply of food for the African savanna’s true predators: lions, cheetahs, wild dogs, and hyenas.
Every year, up to 500,000 calves are born in February and March, at the start of the rainy season. Calves learn to walk within minutes of birth and can keep up with the herd within days. Wildebeests can live for up to 20 years.

There are five known subspecies of Blue Wildebeest in Africa:

C. t. taurinus – Blue wildebeest or bridled gnu

C. t. albojubatus – Eastern white-bearded wildebeest

C. t. cooksoni – Cookson’s wildebeest

C. t. johnstoni – Nyassaland wildebeest

C. t. mearnsi – Western white-bearded wildebeest
