Wildebeest "The Great Space Coaster" (newscaster Gary Gnu), and "The Lion King" (the wildebeest stampede that resulted in Mufasa's death). Michael Flanders wrote a humorous song called "The Gnu", which was very popular when he performed it, with Donald Swann, in a revue called "At the Drop of a Hat", which opened in London on 31 December 1956. The wildebeest is the mascot of the GNU Project and GNU operating system.

Wildebeest recorded when a dispute between two males occurred. Wildebeest do not form permanent pair bonds and during the mating season, or rut, the males establish temporary territories and try to attract females into them. These small territories are about 3000 m, with up to 300 territories per km. The males defend these territories from other males while competing for females that are coming into oestrus. The males use grunts and distinctive behaviour to entice females into their territories. Wildebeest usually breed at the end of the rainy season when the animals are well fed and at their peak of fitness.
