The blue wildebeest (Connochaetes taurinus), also known as blue gnu, brindled gnu, white-bearded gnu, white-bearded wildebeest, or common wildebeest, is a giant antelope of the family Bovidae. William John Burchell, an English naturalist, first described the blue wildebeest in 1824. These species share the genus Connochaetes with black wildebeest (Connochaetes gnu). A study found that these two species have a close polygenetic relationship and diverged as two species a million years ago. The genus has two Greek words, konnos, which means 'beard,' and khaite means 'flowing hair' or 'mane.' The specific scientific name 'taurinus' means bullock or bull is Greek (tauros). These wildebeests are named blue wildebeest due to their silvery-blue sheen coat. Also, the name gnu has its origins in Khoekhoe name of these species 't'gnu.' Originally, the blue wildebeest was placed in the Gorgon genus, and the black wildebeest or white-tailed gnu was in Connochaetes. There are five recognized subspecies of the Connochaetes taurinus, Nyasaland wildebeest (C. t. johnstoni), common wildebeest (C. t. taurinus), western white-bearded wildebeest (C.t. mearnsi), eastern white-bearded wildebeest (C.t. albojubatus), and Cookson's wildebeest (C. t. cooksoni).

The population of this wildebeest is now extinct in Malawi. Around 100 years ago, there were a lot of migratory populations of the wildebeest but now there are only three, Tarangire, Serengeti, and Kafue. The southern African habitat range extends till the Orange river, and the western range till mount Kenya and lake victoria. The habitats occupied by the subspecies are:

The common wildebeest (Connochaetes taurinus taurinus) is found in the regions extending from South Africa and Namibia through Mozambique and from southwest Zambia through south Angola.

How do they reproduce?

The female blue wildebeests can become sexually mature to produce young in 16 months with proper nutrition and the males become mature at two years. However, females breed after the first year of their life. The mating season coincides with the end of the rainy season and it lasts for three weeks. Rut or mating season begins on a full moon night, which shows that the lunar cycle influences reproduction. Also, the testosterone production in males is high at this time making them highly territorial. Males display for females includes rivalry, snorting, digging their horns into the ground against another male. After a male dominates he then tries to lure the female into his territory. Some activities like low-stretch and urination are common during courtship. A receptive female holds still and puts her tail to one side for the copulation process. She can mate with many males. The gestation period lasts for eight and a half months and 80-90% of calves are born within three weeks time. Calves are born or females give birth in the middle of the day and in the middle of their herd. The calves stay closer to their mothers to escape predators and the male calves leave around eight months of age. The survival of these calves in larger herds is more compared to smaller ones.

What is their conservation status?

The conservation status of the blue wildebeests is the Least Concern. The main cause of the death of these species is predation. Other threats they face are diseases, poaching, expansion of land, and fenced areas. The current population in the Serengeti National park, Hange national park, and Etosha national park is stable.
