Black wildebeest
Black wildebeest act as hosts to a number of external and internal parasites. A study of the animal in Karroid Mountainveld (Eastern Cape Province, South Africa) revealed the presence of all the larval stages of the nasal bot flies "Oestrus variolosus" and "Gedoelstia hässleri". The first instar larvae of "G. hässleri" were found in large numbers on the dura mater of wildebeest calves, specially between June and August, and these later migrated to the nasal passages. Repeated outbreaks of mange (scab) have led to large-scale extinctions. The first study of the protozoa in blue and black wildebeest showed the presence of 23 protozoan species in the rumen, with "Diplodinium bubalidis" and "Ostracodinium damaliscus" common in all the animals.
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.
