The Masai Mara National Park in Kenya is located about two hundred and ninety kilometres away from the capital city of Nairobi. It is at this time that the annual wildebeest migration takes place among Kenya Masai Mara and Tanzania Serengeti National Park. This great passage involves over a million animals, chiefly the wildebeest also recognized as Gnu, zebra and gazelle. This voyage is necessitated by the hunt for fresh grazing lands and water by the animals. The shift into Kenya more often than not occurs during the months of June and October. This is because; throughout this period the area experiences rains which causes the grass that is rich in proteins and energy to nurture. The animals then come back to the south in October after the rains move towards south to Serengeti national park once the animals have bushed the grass in the Masai Mara.
The migration of wildebeest in Kenya is more often than not a very lethal period for the animals. It is throughout this move that a considerable number of animals meet their demise. The deaths more often than not occur as a result of marauders such as lion, hyena and the leopard that hunt on the little, old as well as sick animals. The poisonous Nile crocodiles with their colossal jaws attack the animals at the same time as crossing the river. There are also quite a lot of deaths as a result of sinking caused by the wild currents of the Nile River. One more common cause of casualty is the rush caused by the huge number of animals. Nevertheless, this does not lessen their numbers for the reason that between the months of January and March almost similar amount of animals are born to substitute those lost at some point in the migration.
