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. In the "Llama Llama" picture-book series by Anna Dewdney, an anthropomorphized wildebeest named Nelly Gnu is the main character, Llama Llama's best friend, and is also featured in a title
Wildebeest mortality of calves may be as high as 50%. However, in larger aggregations, or small groups living near large herds, survival rates may be over 80%. Groups of wildebeest females and young live in the small areas established by the male. When groups of wildebeest join together, the female to male ratio is higher because the females choose to move to the areas held by a smaller number of males. This female-dominated sex ratio may be due to illegal hunting and human disturbance, with higher male mortality having been attributed to hunting. Today, many wildebeest populations are experiencing rapid declines.
