Black wildebeest
Where it lives alongside the blue wildebeest, the two species can hybridise, and this is regarded as a potential threat to the maintenance of the species. The black wildebeest was once very numerous and was present in Southern Africa in vast herds, but by the end of the 19th century, it had nearly been hunted to extinction and fewer than 600 animals remained. A small number of individuals was still present in game reserves and at zoos, and from these, the population was rescued.
Kenya
The "Big Five" game animals of Africa, that is the lion, leopard, buffalo, rhinoceros, and elephant, can be found in Kenya and in the Masai Mara in particular. A significant population of other wild animals, reptiles and birds can be found in the national parks and game reserves in the country. The annual animal migration occurs between June and September with millions of animals taking part, attracting valuable foreign tourism. Two million wildebeest migrate a distance of from the Serengeti in neighbouring Tanzania to the Masai Mara in Kenya, in a constant clockwise fashion, searching for food and water supplies. This Serengeti Migration of the wildebeest is a curious spectacle listed among the Seven Natural Wonders of Africa.
